  2. Studying Population • Study the relationships between populations and the environment. • Demography – the statistical study of human populations. • Use these numbers to forecast what the population will be like in the future.

  3. Population Density • The average number of people living in an area. • Persons per square mile. • You can tell how large a country is, or discover what areas they live in.

  4. Population Distribution • About 90% of the world’s people live in the Northern Hemisphere. • Lowland areas are heavily populated. • People tend to live in areas that are favorable for settlement.

  5. Population Change • The number of people in an area are a result of these 3 factors: • Birthrate – number of birth per 1,000 in one year. • Death rate – number of deaths per 1,000 per year. • Migration – people moving from one place to another.

  6. Migration • Geographers – study migration by analyzing push factors and pull factors. Push factors are what causes people to leave one place. • Pull factors – attracts people to a location.

  7. Natural Increase • Rate of natural population growth. Number of birth and deaths in a year. • Highest rates of increase are found in Africa and Southwest Asia. • Lowest rates of increase are in Europe and North America.

  8. World Population Trends • Number of people is increasing by 80 million per year. • Some worry about overpopulation. This exists when the number of people is too large to be supported by available resources. • No one knows for sure how many people the world can support.

  9. The Demographic Transition • A model that shows how birthrates and death rates dropped in many western countries as they developed modern economies. • Most of the world’s richest and technological advanced countries have had their birthrates drop.

  10. Future Populations • Population projections are estimates of a future population’s size, age, growth rate, or other characteristics based on current data. • All countries will face population-related challenges. Ex: caring for growing number of children or older people.
