Understanding Population Distribution, Density, and Migration Patterns

This review explores the critical aspects of population distribution and density across the globe, identifying four major population clusters: East Asia, South Asia, Europe, and Southeast Asia. It delves into key demographic concepts such as Total Fertility Rate (TFR), Infant Mortality Rate (IMR), and the Rate of Natural Increase (RNI), which reflect population dynamics. The document also examines migration, including push and pull factors that influence human movement, and various migration streams impacting the U.S., along with interregional and intraregional migration patterns.

  1. UNIT 2 REVIEW POPULATION

  2. POPULATION DISTRIBUTION AND DENSITY

  3. DISTRIBUTION

  4. Portion of the earth’s surface that is habitable for humans. ECUMENE

  5. DENSITY

  6. FOUR MAJOR POPULATION CLUSTERS • East Asia • South Asia • Europe • Southeast Asia

  7. KEY TERMS

  8. TOTAL FERTILITY RATE (TFR) • Number of children predicted to be born to a woman as she passes through fertile years

  9. Infant Mortality Rate (IMR) • Number of deaths of children under 1 year of age per 1,000 births over a year.

  10. Natural growth rate of a population, which is CBR minus CDR expressed as a percentage. A positive RNI indicates a growing population, whereas a negative RNI indicates a population reducing in size. An RNI equal to zero indicates a stabilizing population. Rate of Natural Increase (RNI)

  11. LIFE EXPECTANCY • Average number of years a person is expected to live.

  12. DEMOGRAPHIC TRANSITION

  13. FOOD PRODUCTION

  14. POPULATION PYRAMIDS

  15. MIGRATION

  16. MIGRATION • A permanent move to a new location.

  17. Pull Factor • Factor that attracts a migrant to a region, such as good schools or nice weather.

  18. Push Factor • Factor that causes a migrant to move out of a region, such as high taxes or poor schools.

  19. IMMIGRATION BY COUNTRY

  20. MAJOR MIGRATION STREAMS

  21. MIGRATION STREAMS TO THE U.S.

  22. U.S. INTERREGIONAL MIGRATION

  23. U.S. INTRAREGIONAL MIGRATION
