1 Population and Demographic Population Tensions All the people living in a territory Demography The study of populations The science that provides data about the population in order to study its general characteristics, understand patterns of change, and evaluate the consequences of this change. 1 Million = 1,000,000 1 Billion = 1,000,000,000 1 Trillion = 1,000,000,000,000 There are 7 Billion (7,000,000,000) people in the world

2 Questions What is the current population of the world? What are the 10 countries with the highest population in the world? Rank the continents according to their populations. Which part of the world has the highest % of people over age 35? Since 1950, on which three continents is population increasing the fastest? Where are the areas of highest population density in the world? The lowest density? What are the main factors (physical and human) that influence population density? Answer #1-4 with predictions for 2050.

3 Answers What is the current population of the world? 7 billion What are the 10 countries with the highest population in the world? Rank the continents according to their populations. Asia, Africa, America, Europe, Oceania, Antarctica Which part of the world has the highest % of people over age 35? Europe Since 1950, on which three continents is population increasing the fastest? Africa, Asia, South America AND BEFORE 1950? WHY? Where are the areas of highest population density in the world? The lowest density? What are the main physical and human factors that influence population density? Physical factors: relief, climate, soil Human factors: ages of settlements, economy (traditional and industrial) Answer #1-4 with predictions for 2050.

4 Homework Read Chapter 1 (p ) Use Chapter 1 to finish correcting answers to questions Page 179, Activity #3

5 factors that influence population density Physical factors: relief flat areas climate temperate climate soil fertile soil water Human factors: Ages of settlements (Asia, Europe, Nile River, coastal areas in America and Oceania) Strong economies = higher population Traditional = agriculture SE Asia (India, Indonesia, Vietnam) Industrial = since

6 The world in 2050 Look at the map on page 177. Which populations of the world will grow most between now and 2050? Sub-Saharan Africa, South Asia, South-west Asia, Oceania, North Africa, North America, Central and South America Which population will shrink (decrease)? Europe

7 REFLECTION Read the box at the start of Unit 10. What consequences do you think the increase of population to 9 billion people by 2050 will have on the world? On your life? Write at least 3 for each one.

8 Partners: Birth and Death! First Answer: Activity What is the rate of natural increase? About birthrates, total fertility rate, deathrates, and infant mortality rates: What are they? Why are they different in richer and poorer countries?

9 Activity Without using a book, make a table comparing the United Kingdom and Nigeria, using the following terms: Birth rate, mortality rate, total fertility rate, infant mortality rate, life expectancy, natural rate of increase Be ready to explain why the numbers are different. Example: The birth rate is lower in the UK than in Nigeria because everyone in the UK is too busy watching football to have children.

10 Homework Find the following information about Spain and one less-developed country in the world. Make a table that compares the two. Birth rate, mortality rate, total fertility rate, infant mortality rate, life expectancy, natural rate of increase

11 Migration Emigration: act of leaving a country Immigration: foreign people coming to a country Net migration rate :

12 Migration Make a list of reasons why people would immigrate to a country, and why they would emigrate from a country. Examples: I would immigrate to Spain in order to increase my consumption of jamon. I would emigrate from the United States because jamon serrano is illegal.

13 Net Migration Rates WORLD LIST: na/menos/inmigracion

14 Homework - Read pg. 184,185 and do act. 1 - Read pg. 186,187 and do act 1,2 (186)

15 Developing countries can have bell-shaped pyramids

16 SPANISH DEMOGRAPHICS Population Density: Which parts of Spain are most densely populated? Least densely populated? WHY? (Look at your notes about factors that influence population density ). Rate of Natural Increase: Life expectancy: Number of Foreigners (two countries): % of Workers in the primary sector: Why is the labour force (number of people who can work ) increasing? What do you think this will do to the birthrate? How will this influence the shape of the population pyramid? How is the fertility rate changing for the last 20 years? WHY?
