AP+Geo+Unit+2

Population
The second major unit of the test is the study of human population. This not only looks at the issue of overpopulation, but also at trends and data used in determining demographic principles. Age, sex, race, and ethnicity are examined as well as areas of population growth and decline. Reasons will be analyzed for a region or country's success or failure in controlling population growth. Different models and theories will be examined in relation to place to determine validity. Migration is also included in this unit. Migration does not affect world population growth rates, but it does affect the movement and structure of regional populations. Both push and pull factors are important in determing why people move.
