1. Population Geography

2. Population National Geographic - 7 billion National Geographic - Are You Typical?

3. Key Terms Demography – The statistical study of human populations. Population – The total number of people living in a given area. Population Density – The average number of people living in a given area. (persons per square mile) – Arithmetic: Population/Total Land. Ex: (30 people/10 square miles of land)= 3 ppl/sq mi – Physiologic: Population/Arable Land. Ex: (30 people/5 square miles of land that is farmable)= 6 ppl/sq mi

4. Birthrate – Number of live births each year per 1,000 women. Death Rate – Number of deaths each year per 1,000 people. Immigrants – People who move into a country Emigrants – People who leave a country to live elsewhere

5. Pull Factors – Things that attract people to live in a new location. Push Factors – Things cause people to leave a location. Urbanization – the movement of people from the countryside to cities (growth of cities) Rural – Of, or relating to the countryside.

11. World Population Patterns

15. Population Pyramids Shows the age & sex distribution of a population Shows the history of a country’s population growth—Ex. Baby Boom Generation in U.S.

16. 3 Types of Growth 1.Rapid growth-wide at the base (Ex: Haiti) …looks like a true pyramid 2.Slow growth- straight up and down or a little wider at base than top (Ex: US) 3.Negative growth-broader at top than bottom (Ex: Germany)

20. Brainstorming Reasons why some countries have high birth rates? (Have lots of children?) Reasons for high death rates? Reasons why some countries have low death rates? (Have few or no children?) Reasons for low death rates?
