8 Understanding Society The UK Longitudinal Household Study (UKHLS) Started in with a sample of around 30,000 UK households Household survey Longitudinal survey 15 What happens when people move, households change? But what happens when individuals move? We follow them as long as they are still living in UK (including to institutions) with some exceptions we don t interview them in places it is difficult to get access to, e.g., prisons we also do not follow Temporary Sample Members 16 8

9 Who is interviewed each year? Wave 1: Understanding sampled household all Original Sample Members (OSM) Household A 17 Who is interviewed each year? Wave 1: Understanding sampled household all Original Sample Members (OSM) Household A Wave 2: One household member moves out and forms new household Household B Household C Temporary Sample Member (TSM) Interviewed because living with an OSM 18 9

10 Who is interviewed each year? Wave 1: Understanding sampled household all OSMs Household A Wave 2: One household member moves out and forms new household TSM interviewed because living with an OSM Household B Household C Wave 3: One household member separates from temporary sample member Household D Household E Household F TSM NOT interviewed because NOT living with OSM 19 Who provides the information? household & enumeration grid answered by any adult at the doorstep household questionnaire answered by an adult household member who knows about the household Individual adult questionnaires: face-to-face and selfcompletion questionnaires answered by adults (16+ years) in the household 20 10

11 Who provides the information? Proxy questionnaire answered by spouse or adult child of a respondent if respondent not available for interview shorter than the face-to-face individual questionnaire, consists of factual questions but not subjective attitudinal questions youth self-completion questionnaire answered by10-15 year olds in the household 21 Why Understanding Society for ethnicity research? It is the only longitudinal survey for ethnicity related research in UK It is a multidisciplinary multi-topic survey with Ethnicity as one of its priority areas It includes an Ethnic Minority Boost Sample (EMBS) a new Immigrant and Ethnic Minority Boost sample to be added in wave 6 An Extra Five Minutes of question time is set aside 22 11

12 Multi-disciplinary content Key Topics: significant research domains Education Employment Family and household Health, health behaviours, wellbeing Income, housing, wealth, expenditure & deprivation Attitudes, values and beliefs AND ETHNICITY 23 Ethnicity is one of the priority areas Measures of ethnicity Census ethnic group Own country of birth and year of arrival to UK Parents, grand parents countries of birth Religion Childhood language Questions related to ethnicity Ethnic Identity Britishness Social and friendship networks, their ethnic compositions 24 12

13 Ethnicity related research Are migrants more likely to be over-qualified? If so, are migrants from specific countries more vulnerable? Are income, poverty persistence and material deprivation different across ethnic groups? What explains the difference? Does social network and English language ability matter? Is there an ethnic wage penalty? Does that decrease across generations? Is it a consequence of some ethnic minorities concentrated in low paying jobs? 25 What proportion of people living in UK in 2009/10 when Understanding Society started were born outside of the UK?? 26 13

14 Sample design General population sample (GPS): nationally representative sample of 26,000 households Ethnic minority boost sample (EMBS): 4,000 households with individuals from ethnic minority backgrounds from high ethnic minority concentration areas For ethnicity related research, both samples need to be used together for complete coverage of ethnic groups 27 Screening question At the doorstep interviewer asked Does anyone living at this address come from, or have parents or grandparents from any of the following ethnic groups? The response categories were: Indian, Mixed Indian, Pakistani, Bangladeshi, Sri Lankan, Caribbean/West Indian, Mixed Caribbean/West Indian, North African, Black African, African Asian, Chinese, Far Eastern, Turkish, Middle Eastern / Iranian AND None of these Addresses at which at least one of these categories other than none of these was selected had a positive (but different) selection probability 28 14

Geographical locators are provided School codes are provided Survey data linked to the National Pupil Database (for England only) Access to these data generally require additional permissions available under special or secure license only 34 17

The large sample spread across the whole of UK allows regional level analysis and analysis of minority populations such as single parents, people with disability Health and biomarkers were collected by nurses from a sub-sample See Health Assessment and Biomarker User Guides for further details the British Household Panel Survey sample was added in 2010 (2 nd wave of Understanding Society) allowing analysis of a very long panel 35 There is more! the British Household Panel Survey Longitudinal household survey that started in 1991 with a sample 5,500 households from Great Britain In 1999 the Welsh and Scottish boost samples were added and in 2000 Northern Irish boost sample was added Annual interviews continued until

19 Understanding Society: the UK Household Longitudinal Study DATA STRUCTURE 37 Data structure Data is collected at different levels: adults, young persons and household Data is collected at every wave This is how the data is made available: each type of data based on the source is available as a separate file For each wave, there is one such set of files Linking variables are also provided to match these files 38 19

20 Naming convention to make this easy to follow Same type of data file will always have the same root name A letter wave prefix allows you to identify the wave: a_ is for wave 1, b_ for wave 2 and so on. E.g., the indresp file is called a_indresp in wave 1, b_indresp in wave 2 and so on The same naming convention applies to variables. E.g., the age variable is a_dvage in wave 1, b_dvage in wave

21 41 More about the data Missing data: these are given a negative value - 9: Missing - 8: Valid skip - 7: Proxy respondent - 2: Refuse - 1: Don t Know Imputed data: For some variables, e.g., income, missing components are imputed; Imputation flags are provided

22 More about the data Derived variables: family identifiers: father, mother, partner identifiers Summary variables: number of children in the household, household size Summary scores for question modules such as GHQ, Big Five personality traits, SF-12, SDQ, BMI Variables computed after consistency checks always preferred to the raw unchecked versions Derived Variable names generally have a suffix _dv and are placed towards the end of the data files. 43 Weights Unequal selection probability and Non-response/attrition population estimates based on this sample may be biased if the variable of interest varies across the groups Weighted estimates eliminate this bias as the weights are designed to reduce the impact of those who are overrepresented in the sample. Different weight variables are provided each is appropriate for a different analysis. See USER GUIDE 44 22

23 Clustering and stratification Understanding Society sample has a clustered and stratified sample design To correctly estimate the standard errors the design should be taken into account Variables representing the clusters and strata are provided. 45 Weights and sample design Average monthly wages in UK Estimated mean and 95% confidence interval 46 23
