  1. Population Geography Measuring people and nations

  2. Definitions Population Density How heavily an area is populated. Usually measured by number of people per square mile.

  3. Definitions Population Density Augusta County

  4. Definitions Population Density Virginia

  5. Definitions Population Density United States

  6. The World Population Density Where is worldwide population is generally concentrated? Near seacoasts and sources of fresh water (rivers).

  7. Definitions migration The movement of people from place to place. Why do people migrate?

  8. Definitions Migration: push factors Conditions that make people want to leave a place. • Conflict (war) • Natural hazards (e.g., droughts, floods, famines, volcanic eruptions) • Lack of job opportunities • Agricultural decline • Limits on personal freedom • Overpopulation • Political persecution • Religious persecution • Environmental degradation

  10. Definitions Birthrate Number of live births per 1,000 population.

  11. Definitions Fertility rate The average number of children a woman has during her lifetime.

  12. Definitions Mortality rate (Death rate) Number of deaths per 1,000 people.

  13. Definitions Infant mortality rate Number of infant deaths (in first year) per 1,000 live births.

  14. Definitions Natural increase. Birthrate – deathrate = natural increase.

  15. Definitions Natural increase. Birthrate – deathrate = natural increase.

  16. Definitions Population growth rate

  17. Definitions Life expectancy The average length of life.

  18. Definitions Age distribution The percentage of each age group in a population.

  19. Definitions Age distribution Population pyramid

  20. Definitions Age distribution An even age distribution indicates a developed nation.

  21. Definitions Age distribution An uneven age distribution indicates a developing nation.

  22. Definitions Literacy rate The percentage of adults who can read and write. What is the relationship between literacy and wealth?

  23. Definitions per capita GDP The value of goods and services produced by the average person in the economy. A measurement of how wealthy or poor people are in a nation.
