1 1 Codebook for Pew Research Center s Global Restrictions on Religion Data (published DATE TK) Background In December 2009, Pew Research Center released Global Restrictions on Religion, the first in a series of annual reports on a data-coding project that seeks to measure levels of government restrictions on religion and social hostilities involving religion around the world. The reports use two indexes to rate nearly 200 countries and self-governing territories on their levels of restrictions and hostilities. The Government Restrictions Index (GRI) is based on 20 indicators of ways that national and local governments restrict religion, including through coercion and force. The Social Hostilities Index (SHI) is based on 13 indicators of ways in which private individuals and social groups infringe upon religious beliefs and practices, including religiously biased crimes, mob violence and efforts to stop particular religious groups from growing or operating. The reports include data on the number and types of documented incidents of religionrelated violence, including terrorism and armed conflict. As of February 2015, Pew Research had published six reports on global restrictions on religion, analyzing a total of seven years worth of data (the first two reports covered a total of three years, from 2007 to 2009). Each report has included an appendix listing country-level scores on every indicator for the time period covered by the report, but until now, the data were not available in a downloadable format. In order to provide social science researchers and the general public with easier access to the data, Pew Research Center now has released the full dataset and this explanatory document ( codebook ). The codebook explains the data-coding process, sources of information and construction of the indexes. It details some methodological changes that have been made since the project began, and it briefly describes efforts by Pew Research Center to assess potential sources of measurement bias. It includes an annotated version of the questionnaire used to code data throughout the project, with definitions of key terms and scoring procedures. The data are presented as a long-format dataset, in which each row is a country-year observation (for example, Afghanistan, 2007 ). The columns contain all of the variables presented in Pew Research Center s annual reports on restrictions on religion, as well as some additional variables analyzed in separate studies. The dataset currently contains data from 2007 through 2013; as

2 2 additional years of data are coded, the dataset will be updated. 1 The data also can be explored interactively through Pew Research Center s Global Religious Futures website. To allow for reliable analysis of trends over time, Pew Research Center has tried to keep the coding procedures as consistent as possible from year to year. However, some changes have been necessary, mainly due to the availability of information sources. The changes are detailed below. The codebook proceeds in three parts. First, it explains the methodology and coding procedures used to collect the data. Second, it discusses the Government Restrictions Index and Social Hostilities Index, including what they measure and how they are calculated. Finally, it describes each of the variables included in the dataset, along with answer values and definitions of key terms. Overview of Procedures The methods used to assess and compare restrictions on religion were developed by former Pew Research Center senior researcher Brian J. Grim in consultation with other members of the center s staff, building on a methodology that Grim and Professor Roger Finke developed while at the Pennsylvania State University s Association of Religion Data Archives. 2 The goal was to devise quantifiable, objective and transparent measures of the extent to which governments and societal groups impinge on the practice of religion. The findings were used to rate countries and selfgoverning territories on two indexes that are reproducible and can be periodically updated. This research goes beyond previous efforts to assess restrictions on religion in several ways. First, Pew Research Center has coded (categorized and counted) data from a variety of sources, including reports by the U.S. State Department, the U.N. Special Rapporteur on Freedom of Religion & Belief, the Council of the European Union, the United Kingdom s Foreign & Commonwealth Office, Human Rights Watch, the International Crisis Group, Freedom House and Amnesty International, to mention just a few. Pew Research Center coders have looked to the sources only for specific, well-documented facts, not opinions or commentary. Second, Pew Research Center staff have used extensive data-verification checks that reflect generally accepted best practices for such studies, such as double-blind coding (coders do not see 1 Initially, Pew Research Center analyzed data on religious restrictions for 12-month periods from July 1-June 30 (e.g., July 1, June 30, 2010). The mid-year to mid-year time frame was used from In 2011, the time frame for the analysis shifted to calendar years, in part because most of the primary sources used in the study were then based on calendar years. For the sake of simplicity, this codebook and the accompanying dataset use calendar-year designations only. For example, the baseline year of the study (mid-2006 to mid-2007) is reported as Users should keep this in mind when working with data from years prior to See Grim, Brian J. and Roger Finke International Religion Indexes: Government Regulation, Government Favoritism, and Social Regulation of Religion.

The coding also has identified how widespread and intensive the restrictions were in each country. Countries and Territories The 198 countries and self-administering territories covered by the data contain more than 99.5% of the world s population. 4 They include 192 of the 193 member states of the United Nations as of 2013, plus six self-administering territories Kosovo, Hong Kong, Macau, the Palestinian territories, Taiwan and Western Sahara. Reporting on these territories does not imply any position on what their international political status should be, only recognition that the de facto situations in these territories require separate analysis. Although the 198 countries and territories vary widely in size, population, wealth, ethnic diversity, religious makeup and form of government, the coding does not attempt to adjust for such differences. Poor (or developing) countries are not scored differently from wealthy (or developed) ones. Countries with religiously diverse populations are not expected to have more social hostilities than homogeneous ones, and democracies are not assessed differently from authoritarian regimes. The primary sources indicate that the North Korean government is among the most repressive in the world, including toward religion. But because independent observers lack regular access to North Korea, the sources are unable to provide the kind of specific, timely information that forms the basis of this data. Therefore, North Korea is not included on either index. Information Sources Pew Research Center initially identified 18 widely available, frequently cited sources of information on government restrictions on religion and social hostilities involving religion around the world. Since the inception of the project, however, some information sources have been discontinued or have not been updated; new sources have been substituted to compensate for these changes. 3 Inter-rater reliability assessments were conducted using weighted Cohen s kappa in SPSS The reports initially included Northern Cyprus as a separate territory. This was discontinued beginning in 2010, reducing the number of countries and territories included in the report to 197. After South Sudan separated from Sudan in 2011, the number of countries and territories in the report returned to 198. This dataset does not include data for Northern Cyprus.

4 4 The primary sources, which are listed below, include reports from U.S. government agencies, several independent, nongovernmental organizations and a variety of European and United Nations bodies. Although most of these organizations are based in Western countries, many of them depend on local staff to collect information across the globe. Pew Research Center does not use the commentaries, opinions or normative judgments of the sources; the sources are combed only for factual information on specific policies and actions.

5 5 Two major areas in which data sources have changed are religion-related terrorism and war. Pew Research Center initially relied on the information on terrorism and war in the U.S. State Department reports and the International Crisis Group reports. Starting in 2009, researchers added two new sources: the U.S. National Counterterrorism Center s Worldwide Incident Tracking System (WITS) for data on religion-related terrorism, and Sweden s Uppsala University Conflict Data Program s Armed Conflict Database for data on religion-related war. The U.S. government discontinued WITS in 2011, however, and, beginning in 2012, the coding project reverted to using U.S. State Department reports for data on religion-related terrorism, while continuing to use the Uppsala database to track religion-related war. In 2013, Pew Research Center also began using data from the Global Terrorism Database maintained by the University of Maryland s National Consortium for the Study of Terrorism and Responses to Terrorism. Since the University of Maryland database is also a primary source of information for the U.S. State Department s Country Reports on Terrorism, Pew Research Center staff sought to ensure that no terrorism incidents were double-counted between the two sources. Another area in which data sources have changed is human rights. The Human Rights First reports have not been updated since 2009, so annual Freedom House reports were substituted beginning in Additionally, the Hudson Institute publication Religious Freedom in the World, by Paul Marshall, has not been updated since its 2008 release. To provide more recent data, Human Rights Without Frontiers Freedom of Religion or Belief newsletters were substituted starting in Finally, Amnesty International s country reports were not available for 2013, so coding for that year occurred without them. The Coding Instrument Pew Research Center staff developed a battery of questions, similar to a survey questionnaire, about various types of government restrictions on religion and social hostilities involving religion. Each year, coders consult the primary sources to answer each question separately for each country. While the State Department s annual reports on International Religious Freedom generally contain the most comprehensive information, the other sources provide additional factual detail that is used to settle ambiguities, resolve contradictions and help in the proper scoring of each question. The questionnaire, or coding instrument, generates a set of numerical measures on restrictions in each country. These numerical measures are used as variables in the analysis done for the annual restrictions reports. The coding process requires the coders to check all the sources for each country. Coders determine whether each source provides information critical to assigning a score, provides supporting

6 6 information but not critical additional facts, or provides no substantive information on that particular country. Multiple sources of information are available for all countries and selfadministering territories with populations greater than 1 million. Most of the countries and territories analyzed by Pew Research Center are multisourced; only small, predominantly island, countries have a single source, namely, the U.S. State Department reports. Coding the United States presents a special problem since it is not included in the State Department s annual reports on International Religious Freedom. Accordingly, Pew Research Center coders also look at reports from the U.S. Department of Justice and the FBI on violations of religious freedom in the United States, in addition to consulting all the primary sources, including reports by the United Nations, Human Rights Watch, Freedom House, the International Crisis Group and the U.K. Foreign & Commonwealth Office, many of which contain data on the United States. The Coding Process Pew Research Center employs strict training and rigorous coding protocols to make its coding as objective and reproducible as possible. Coders work directly under an experienced researcher s supervision, with additional direction and support provided by other Pew Research Center researchers. Each year, a new group of coders undergoes an intensive training period that includes a thorough overview of the research objectives, information sources and methodology. Countries are double-blind coded by two coders (coders do not see each other s ratings), and the initial ratings are entered into an electronic document (coding instrument) that includes details on each incident. The coders begin by filling out the coding instrument for each country using the information source that has the most comprehensive information, typically the State Department s International Religious Freedom report. The protocol for each coder is to answer every question on which information is available in the initial source. Once a coder has completed that process, he or she then turns to the other sources. As new information is found, this also is coded and the source duly noted. Whenever ambiguities or contradictions arise, the source providing the most detailed, clearly documented evidence is used. After two coders have independently completed the coding instrument for a particular country, their scores are compared by a researcher. Areas of discrepancy are discussed at length with the coders and are reconciled to arrive at a single score on each question for each country. The data for each country are then combined into a master file, and the answers and substantiating evidence are logged into a database.

7 7 After all countries are completely coded and all answers and substantiating evidence are logged, the coders and supervising researchers compare the scores from the most recent year with those from the previous year. They identify scores that have changed and review the substantiating evidence for each year to determine whether the change is substantive or a result of coding error, such as information that has been overlooked. In cases in which the change is found to result from coding error, the coders change their scores accordingly. On several of the questions measuring social hostilities (SHI_Q_6, SHI_Q_7, SHI_Q_8, SHI_Q_9, SHI_Q_10, SHI_Q_11, SHI_Q_12 and SHI_Q_13), coders are instructed to look not only at the current annual coding period but also at two prior years of data to assess whether hostilities in those prior years have a continuing impact on religious tensions. For example, a major outbreak of violence between religious groups, a brutal attack on an individual who has switched religions or a highly publicized honor killing may have a chilling effect on religious activity that extends beyond a single year. Accordingly, coders are instructed to take into account up to three years worth of information in the coding for these questions. During the first years of coding, the coding instrument continually was evaluated for possible defects. The wording of the questions was designed to be precise, comprehensive and objective, so that, based on the same data sources, the coding could be reliably reproduced by others. In subsequent years, the definitions of some key terms have been elaborated in an effort to ensure consistency from year to year, resulting in annotations to the questionnaire used by the data coders. But no substantive changes have been made in the wording of the questions that constitute the Government Restrictions Index or the Social Hostilities Index since publication of the first religious restrictions report in December The sources used in the coding sometimes provide differing descriptions of the same situation or incident. Coders generally have found few cases in which one source flatly contradicts another on a critical issue of fact. When significant contradictions do arise such as when sources provide widely differing estimates of the number of people displaced due to religion-related violence the source that cites the most specific and authoritative documentation is used. The coders are instructed to disregard broad, unsubstantiated generalizations regarding abuses and to focus on reports that contain clear, precise documentation and factual details, such as names, dates and places where incidents occurred. Pew Research Center also uses inter-rater reliability tests to assess the quality of the data. These tests assess the extent to which the two coders for each country agree on the data they code. Interrater reliability scores are computed by comparing the coders independent, blind ratings. These

8 8 inter-rater reliability tests are a common measure of the quality of data and coding instruments; the inter-rater reliability scores generally have been above 0.7, which is considered an acceptable level. Restriction of Religion Indexes Pew Research Center uses two 10-point indexes the Government Restrictions Index and the Social Hostilities Index to rate 198 countries and territories on their levels of restrictions. As noted above, the GRI is based on 20 indicators of ways that national and local governments restrict religion, including through coercion and force. The SHI is based on 13 indicators of ways in which private individuals and social groups infringe on religious beliefs and practices, including religiously biased crimes, mob violence and efforts to stop particular religious groups from growing or operating. In addition to measuring countries levels of restrictions and hostilities involving religion, the reports analyze changes in restrictions on an annual basis. The reports categorize the amount of change in each country s scores in two ways, numerically and by percentile. First, countries are grouped into categories depending on the size of the numeric change in their scores from year to year on the two indexes: changes of two points or more in either direction, changes of at least one point but less than two points, changes of less than one point, or no changes at all. Second, the restrictions reports categorize the levels of government restrictions and social hostilities in each country by percentiles. As a benchmark, the reports use results from the baseline year of the study (2007). Scores in the top 5% on each index in the baseline year were categorized as very high. The next highest 15% of scores were categorized as high, and the following 20% were categorized as moderate. The bottom 60% of scores were categorized as low. Pew Research Center reports all figures in the restrictions reports and dataset to one decimal place. However, the calculations of the Government Restrictions Index and Social Hostilities Index often result in numbers beyond one decimal place, which can have implications for the presentation of countries index scores and countries assignments to levels of government restrictions and social hostilities. It also could affect assessments of index score changes for a given country between years. As a result, there may be a few minor discrepancies if users of this dataset attempt to recreate the indexes from the component variables. Government Restrictions Index Coding multiple indicators makes it possible to construct a Government Restrictions Index of sufficient gradation to allow for meaningful cross-national comparisons. An additional advantage

9 9 of using multiple indicators is that it helps mitigate the effects of measurement error in any one variable, providing greater confidence in the overall measure. Pew Research Center codes 20 indicators of government restrictions on religion. These 20 items are added together to create the GRI. In two cases (GRI_Q_19 and GRI_Q_20), these items represent an aggregation of several closely related questions (for details, see discussion of variables at the end of this codebook). The GRI is a fine-grained measure created by adding the 20 items on a 0-to-10 metric, with zero indicating very low levels of government restrictions on religion and 10 indicating extremely high levels of restrictions. The 20 questions that form the GRI are coded in a standard scale from zero to one point, while gradations among the answers allow for partial points to be given for lesser degrees of the particular government restriction being measured. The overall value of the index is calculated and proportionally adjusted so that it has a maximum value of 10 and a possible range of zero to 10 by dividing the sum of the variables by two. A test of whether the 20 items are statistically reliable as a single index produced a scale reliability coefficient above 0.9 for each year from Since coefficients of 0.7 or higher are generally considered acceptable, it is appropriate to combine these 20 items into a single index. Social Hostilities Index In addition to government restrictions, violence and intimidation in societies also can limit religious beliefs and practices. Accordingly, Pew Research Center staff track more than a dozen indicators of social impediments on religion. Once again, coding multiple indicators makes it possible to construct an index that shows gradations of severity or intensity and allows for comparisons among countries. The Social Hostilities Index is constructed by adding together the 13 indicators based on a 0-to-10 metric, with zero indicating very low impediments to religious beliefs and practices and 10 indicating extremely high impediments. The various questions that form the index are coded in a standard scale from zero to one point, while gradations among the answers allow for partial points to be given for lesser degrees of the particular hostilities being measured. The indicators are added together and set to have a possible range of zero to 10 by dividing the sum of the variables by 1.3. One of these items (SHI_Q_1) represents an aggregation of several closely related questions (for details, see discussion of variables at the end of this codebook). 5 Scale reliability tests were performed using Cronbach s alpha in Stata 13.

10 10 As with the Government Restrictions Index, various types of violence and intimidation are combined on the SHI. A test of whether these 13 items are statistically reliable as a single index produced a scale reliability coefficient of 0.87 or higher each year from Since coefficients of 0.7 or higher are generally considered acceptable, it is statistically appropriate to combine these items into a single index. Overall Restrictions Pew Research Center also analyzes overall restrictions on religion, which take into account both government restrictions and social hostilities to provide a broader sense of the limits on religious belief and practice in a country. A country s overall level of restrictions for a particular year is its maximum level on either index (the Government Restrictions Index or the Social Hostilities Index) for that year. For example, if a country had high government restrictions and low social hostilities, it would have high overall restrictions; if it had low government restrictions and moderate social hostilities, it would have moderate overall restrictions. Changes in overall levels of restrictions are calculated for each country by comparing its scores on both indexes (the GRI and the SHI) from year to year. When a country s scores on the GRI and the SHI change in the same direction (both increased or both decreased), the greater amount of change determines the category. For instance, if the country s GRI score increased by 0.8 and its SHI score increased by 1.5, the country would be put into the overall 1.0 to 1.9 increase category. When a country s score increases on one index but decreases on the other, the difference between the amounts of change determines the grouping. For example, if the country s GRI score increased by 2.0 and its SHI score decreased by 1.5, the country would go into the overall 0.1 to 0.9 increase category. When a country s score on one index stays the same and its score on the other index changes, the amount of change in the latter index is used to assign the category. Regional Medians The religious restrictions reports include median index scores for five geographic regions: the Americas, Asia and the Pacific, Europe, the Middle East and North Africa and sub-saharan Africa). Replication of these median scores may result in slightly different numbers, based on the rounding procedures used in different statistical software packages. The countries included in each region are listed in the reports. How Examples Are Coded

11 11 Examples of each type of government restriction or social hostility are generally counted in a single measure on the GRI or SHI. For instance, a restriction on proselytizing (sharing one s faith with the intent of persuading another to join the faith) is not also counted as a restriction on conversion (an individual changing his/her religion). In some situations, however, an individual restriction or hostility may be part of a broader set of restrictions or hostilities. For instance, a mob attack by members of one religious group on an individual of another religion may be an isolated event and counted just under question SHI_Q_2: Was there mob violence related to religion? However, if such an attack triggers repeated attacks between religious groups, it also might be an indication of sectarian or communal violence, which by definition involves two or more religious groups facing off in repeated clashes. In such a case, the mob attack also would be counted under question SHI_Q_3: Were there acts of sectarian or communal violence between religious groups? Religion-Related Terrorism and Armed Conflict Terrorism and war can have huge direct and indirect effects on religious groups, including destroying religious sites, displacing whole communities and inflaming sectarian passions. Accordingly, Pew Research Center staff tally the number, location and consequences of religionrelated terrorism and armed conflict around the world, as reported in the same primary sources used to document other forms of intimidation and violence. However, war and terrorism are sufficiently complex that it is not always possible to determine the degree to which they are religiously motivated or state sponsored. Out of an abundance of caution, the studies do not include this data in the Government Restrictions Index. They are factored instead into the index of social hostilities involving religion, which includes one question specifically about religion-related terrorism (SHI_Q_4) and one question specifically about religion-related war or armed conflict (SHI_Q_5). In addition, other measures in both indexes are likely to pick up spillover effects of war and terrorism on the level of religious tensions in society. For example, hate crimes, mob violence and sectarian fighting that occur in the aftermath of a terrorist attack or in the context of a religion-related war would be counted in the Social Hostilities Index, and laws or policies that clearly discriminate against a particular religious group would be registered on the Government Restrictions Index. For the purposes of these studies, the term religion-related terrorism is defined as premeditated, politically motivated violence perpetrated against noncombatants by subnational groups or clandestine agents that have some identifiable religious ideology or religious motivation. It also includes acts carried out by groups that have a nonreligious identity but affect religious personnel, such as clergy. Readers should note that it is the political character and motivation of the groups, not the type of violence, that is at issue here. For instance, a bombing would not be classified as

12 12 religion-related terrorism if there was no clearly discernible religious ideology or bias behind it unless it was directed at religious personnel. Religion-related war or armed conflict is defined as armed conflict (a conflict that involves sustained casualties over time or more than 1,000 battle deaths) in which religious rhetoric is commonly used to justify the use of force, or in which one or more of the combatants primarily identifies itself or the opposing side by religion. Changes in the Coding During the years Pew Research Center has been collecting data on global restrictions on religion, a few changes have been made in the coding procedures. While Pew Research Center staff have endeavored to keep the procedures as consistent as possible, some adjustments were necessary, mostly due to changes in sources or improvements in database management. Consolidating to a New Database For the first few years of data collection, information on the number, type and location of incidents of government force and social violence toward religious groups, as well as deference to religious authorities in matters of law, were coded at the province level. Each year, the province numbers were summed and put into separate country-level files. In 2010, Pew Research Center staff began creating a database that integrated all province- and country-level data on religious restrictions. During this process, Pew Research staff reviewed any discrepancies between the province files and the sums that had been transferred to the country files and made appropriate corrections. The adjustments were relatively minor and had negligible impact on countries index scores on average, less than points on the 10-point indexes. Beginning with the 2012 data (analyzed in 2013), Pew Research stopped coding data at the province level; all data are coded at the country level. Consolidating the restrictions data into the database also entailed a review of the data on harassment of religious groups. In particular, instances of harassment from 2007 had been stored as answers to open-ended questions; in a few cases, they were recoded to match the categories used in subsequent years. Changing Time Period of Analysis Initially, Pew Research staffers coded the restrictions data for 12-month periods from July 1-June 30 (e.g., July 1, 2009-June 30, 2010). Beginning in 2011, the data collection shifted to a calendar year (e.g. Jan. 1, Dec. 31, 2011). The shift to calendar years was made, in part, because most of the primary sources used in the studies are based on calendar years.

13 13 Because of the shift in time frame, the data do not include incidents that occurred during the period from July 1, 2010, to Dec. 31, While this misses some incidents that occurred during the second half of 2010, events that had an ongoing impact such as a change to a country s constitution or the outbreak of a religion-related war were captured by the coding. Researchers carefully reviewed the situation in each country and territory during this six-month period and made sure that restrictions with an ongoing impact were not overlooked. Impact of Changes in Coding Procedures or Sources Some of the year-to-year differences on the indexes could reflect minor changes in coding procedures or changes in the information sources. For example, the coding shows a decrease in GRI_Q_3 ( Taken together, how do the constitution/basic law and other national laws and policies affect religious freedom ) between the baseline year of the study and the following year that appears to have been the result of a change in the way the question was coded. During the first year coded (2007), the coders were more likely to give countries the highest possible score on this question (indicating the national government does not respect religious freedom) than in either of the two subsequent years. A post-coding review found that coders initially were more likely to code the presence of a few restrictions on religious freedom by the government as a 1. Starting in 2008, however, coders had a higher bar for coding 1 on this question: The presence of restrictions alone was not sufficient; there also had to be clear harassment or abuse of religious groups or individuals. This standard has been applied in all subsequent years. However, those who use the religious restrictions dataset should be cautious when analyzing changes in GRI_Q_3 in the initial years of the study. Among the areas where changes in the sources likely had an impact is religion-related terrorism (SHI_Q_4). Some year-to-year increases in this component of the Social Hostilities Index could reflect the use of sources that provide greater detail on terrorist activities than the sources used in the first few years of the study, as discussed above in the section on Information Sources. However, because Pew Research Center consistently used the U.S. State Department s Country Reports on Terrorism as a source in all years of data collection, the overall coding of religionrelated terrorism should generally be comparable from year to year. However, those who use the dataset should be cautious in drawing conclusions from minor changes in SHI_Q_4. Finally, there was a change in the early years of the study in the instructions for coding two variables on the Government Restrictions Index: one measuring constitutional or basic law provisions protecting religious freedom (GRI_Q_1) and one measuring constitutional qualifications or contradictions of those protections (GRI_Q_2). As a result of a review of coding procedures,

14 14 these variables were retrospectively back-coded so that the instructions to the coders for the period from 2007 to 2008 matched the protocols used starting in This resulted in small changes to the 2007 and 2008 Government Restrictions Index scores; as a result, the scores included in this dataset vary from those reported in the baseline year of the study. Potential Biases There are several potential biases in the data that Pew Research Center has identified and sought to assess, conducting various kinds of tests and sensitivity analyses, some of which have been published independently. 6 As noted earlier in the codebook, North Korea is not included on either index. The primary sources used for this study indicate that the North Korean government is among the most repressive in the world, including toward religion. But because independent observers lack regular access to North Korea, the sources are unable to provide the kind of specific, timely information that forms the basis of this study. This raises two important issues concerning potential information bias. The first is whether other countries that limit outsiders access and that may seek to obscure or distort their record on religious restrictions were adequately covered by the sources used in the coding. In the early years of the study, researchers reviewed the coding of several limited-access countries and found information on those countries in multiple primary sources. Each of the limited-access countries also was covered by other secondary quantitative datasets on religious restrictions that have used a similar coding scheme, including earlier years of coded State Department report data produced by Grim at the Pennsylvania State University s Association of Religion Data Archives (ARDA) project (four datasets); independent coding by experts at the Hudson Institute s Center for Religious Liberty using indexes also available from ARDA (one dataset); and content analysis of country constitutions conducted by the Becket Fund for Religious Liberty (one dataset). Pew Research Center staff used these datasets for cross-validation. Thus, contrary to what one might expect, even most countries that limit access to information tend to receive extensive coverage by groups that monitor religious restrictions. The second key question the flip side of the first is whether countries that provide freer access to information receive higher scores simply because more information is available on them. As described more fully in the methodology in the baseline report ( Global Restrictions on Religion, 6 Grim, Brian J. and Richard Wike Cross-Validating Measures of Global Religious Intolerance: Comparing Coded State Department Reports with Survey Data and Expert Opinion. Politics and Religion. See also, Grim, Brian J. and Roger Finke International Religion Indexes: Government Regulation, Government Favoritism, and Social Regulation of Religion. Interdisciplinary Journal of Research on Religion.

15 15 published in December 2009 and covering the period from 2007 to 2008), Pew Research Center staff compared the length of State Department reports on open-access countries with those of more limited-access countries. The comparison found that the median number of words was approximately three times as large for the limited-access countries as for the open-access countries. This suggests that problems in open-access countries are generally not over-reported in the State Department reports. Only when it comes to religion-related violence and intimidation in society do the sources report more problems in the freer-access countries than in the limited-access ones. However, the Social Hostilities Index includes several measures such as SHI_Q_8 ( Did religious groups themselves attempt to prevent other religious groups from being able to operate? ) and SHI_Q_11 ( Were women harassed for violating religious dress codes? ) that are less susceptible to such reporting bias because they capture general social trends or attitudes as well as specific incidents. With these limitations in mind, it appears that the coded information on social hostilities is a fair gauge of the situation in the vast majority of countries and a valuable complement to the information on government restrictions. Data on social impediments to religious practice can more confidently be used to make comparisons among countries with sufficient openness, which includes more than nine-in-ten countries covered in the coding. A 2010 analysis by Grim and Richard Wike, Pew Research Center s director of global attitudes research, tested the reliability of the State Department reports on social impediments to religious practice by comparing public opinion data with data coded from the reports in previous years by Grim and experts at Penn State. They concluded that the understanding of social religious intolerance embodied in the State Department reports is comparable with the results of population surveys and individual expert opinion. 7 Another possible source of information bias may arise from the use of U.S. State Department reports and other English-language sources that, in turn, are often based on local media accounts. Do the sources used in the coding fairly and accurately reflect what has been reported by local media in other languages? Or is important information effectively lost in translation? To assess this albeit in a limited fashion Pew Research Center assigned native-spanishspeaking staff to analyze the content of articles with reports of government restrictions on religion and social hostilities involving religion from the Mexican daily newspaper La Jornada. The analysis covered time periods identical to two covered by this study: the baseline year (2007) and the fourth year of this study (2010). 7 See Grim, Brian J. and Richard Wike Cross-Validating Measures of Global Religious Intolerance: Comparing Coded State Department Reports with Survey Data and Expert Opinion. Politics and Religion.

16 16 La Jornada articles were initially selected for analysis if the title made some reference to religion, and then the article itself was coded using the same Government Restrictions Index questions and Social Hostilities Index questions used in the study. Specifically, the content analysis of La Jornada articles examined 18 of the 20 questions in the Government Restrictions Index and all 13 questions in the Social Hostilities Index. (The two GRI questions excluded from the analysis were GRI_Q_1 and GRI_Q_2, because they both relate only to the country s constitution, rather than to actions of the government or activities of social groups and individuals.) The expectation at the outset of this analysis was that a Mexican daily newspaper would contain many more reports of religious restrictions and hostilities than the English-language sources used by Pew Research Center in its cross-national coding. However, the analysis found that the coded news from La Jornada was largely consistent with coding using the study s primary sources. While a similar comparison for other countries might not yield the same results especially in countries where press freedom is more limited this analysis provides some confirmation of the reliability of Pew Research Center s coding across years. Additional Variables From time to time, Pew Research Center has collected information on additional questions (or variables) that are not included in determining scores on the Government Restrictions Index or Social Hostilities Index. These include a question on whether a country has a religious police force and a question on whether a country has laws banning blasphemy, apostasy or defamation of religion. 8 These questions are included in the dataset for this study and are discussed below. 8 See Pew Research Center s Fact Tank blog post on March 19, 2014, Religious Police Found in Nearly One-in-Ten Countries Worldwide, and its Nov. 21, 2012, report Laws Penalizing Blasphemy, Apostasy and Defamation of Religion are Widespread. (A slightly different version of the blasphemy and apostasy question was analyzed in Pew Research Center s August 2011 religious restrictions report, Rising Restrictions on Religion. )

17 17 Variables Used in the Government Restrictions Index and Social Hostilities Index To assess the level of religious restrictions and hostilities around the world, Pew Research Center selected 20 questions for use as variables in the Government Restrictions Index (GRI) and 13 questions for use as variables in the Social Hostilities Index (SHI). This section provides question wording, answer values and definitions of terms. The section generally follows the presentation of the questions in the Summary of Results section of the annual religious restrictions reports; where necessary, it explains how the dataset deviates from the Summary of Results. Variables for the Government Restrictions Index GRI_Q_1: Does the constitution, or law that functions in the place of a constitution (basic law), specifically provide for freedom of religion or include language used in Article 18 of the United Nations Universal Declaration of Human Rights? 0= Yes 0.50= The constitution or basic law does not specifically provide for freedom of religion but does protect some religious practices 1.0 This question measures the presence or absence of provisions protecting religious freedom in the country s constitution. This definition is based on Article 18 of the U.N. s Universal Declaration of Human Rights, which states: Everyone has the right to freedom of thought, conscience and religion; this right includes freedom to change his religion or belief, and freedom, either alone or in community with others and in public or private, to manifest his religion or belief in teaching, practice, worship and observance. GRI_Q_2: Does the constitution or basic law include stipulations that appear to qualify or substantially contradict the concept of religious freedom? 0.33= Yes, there is a qualification 0.67= Yes, there is a substantial contradiction and only some religious practices are protected 1.00= Religious freedom is not provided in the first place This question builds on GRI_Q_1, measuring whether the constitutional provisions are limited by other provisions. A qualification means that religious freedom is provided but some limit is set, such as allowing for religious freedom as long as there is public order. A contradiction means that religious

18 18 freedom is provided, but only for some people and/or in some circumstances; it also can mean that a country s laws or government actions cannot contradict the precepts of a certain religion. GRI_Q_3: Taken together, how do the constitution/basic law and other national laws and policies affect religious freedom? 0= National laws and policies provide for religious freedom, and the national government respects religious freedom in practice 0.33= National laws and policies provide for religious freedom, and the national government generally respects religious freedom in practice; but there are some instances (e.g., in certain localities) where religious freedom is not respected in practice 0.67= There are limited national legal protections for religious freedom, but the national government does not generally respect religious freedom in practice 1.00= National laws and policies do not provide for religious freedom and the national government does not respect religious freedom in practice This question is an overall measure of the state of religious restrictions in a country, based on the information sources used in the study. This includes the opening statements in the State Department s International Religious Freedom reports, which discuss the overall extent to which the country s government protects religious freedom. It also includes the coders aggregate assessment of the level of religious freedom in the country. GRI_Q_4: Does any level of government interfere with worship or other religious practices? 0.33= Yes, in a few cases 0.67= Yes, in many cases 1.00= Government prohibits worship or religious practices of one or more religious groups as a general policy This question measures whether and to what extent the government interferes with religious groups worship or religious practices. A few cases means only one or two isolated situations, while many cases means more than two situations or one situation that affects many congregations or groups, but falls short of a general government policy prohibiting the worship or religious practices of one or more religious groups. Worship or religious practices includes active worship, such as at a religious service; it also includes private religious practices, such as prayer or other daily activities that are governed by religious beliefs. GRI_Q_5: Is public preaching by religious groups limited by any level of government?

19 = Yes, for some religious groups, for all religious groups This question includes restrictions on outdoor prayer meetings and other forms of preaching that do not occur inside a church, synagogue, mosque or temple. Public preaching must involve activities in a public setting, such as houses of worship or other settings where the preacher interacts with the public. It does not include worship that is private in nature, such as prayer in a residence. GRI_Q_6: Is proselytizing limited by any level of government? 0.50= Yes, for some religious groups, for all religious groups This question includes restrictions on efforts by religious groups or individuals to persuade others to join their faith. Examples include outright bans on proselytizing by some or all groups, as well as incidents in which security forces or other government officials attempted to stop an individual or group from proselytizing. GRI_Q_7: Is converting from one religion to another limited by any level of government? This question includes outright bans on conversion, as well as government policies that effectively limit conversion, such as restrictions on changing one s religion on official identify cards. GRI_Q_8: Is religious literature or broadcasting limited by any level of government? This question includes limits on internet use. It also includes extensive restrictions on literature, broadcasting or internet use that do not exempt religious groups. GRI_Q_9: Are foreign missionaries allowed to operate? 0= Yes 0.50= Yes, but with restrictions 1.0 Foreign missionaries are representatives of religious groups engaged in proselytizing or development work. Restrictions include limits on missionaries activities, as well as things that affect their ability to enter a
