Title: Population Geography


1
Population Geography
  • Migration

2
Vocabulary
  • Migration - A permanent move to a new location
  • Immigration - Migration from a location
  • Emigration - Migration to a location

3
Questions
  • Why do people migrate?
  • How have social, economic, political, and
    environmental factors influenced migration?

4
Push and Pull Factors
  • People decide to migrate because of push and pull
    factors. A push factor induces people to leave a
    location. A pull factor induces people to move
    to a new location.

5
Push Factor - Overpopulation
  • People often leave areas that are heavily
    populated.

6
Push Factor - Religious Persecution
  • When people cannot worship as they wish they
    migrate. The pilgrims that landed at Plymouth
    were fleeing religious persecution.

7
Push Factor - Lack of Jobs
  • The vast majority of people migrating from Latin
    America, Africa, and Asia are migrating because
    there are no jobs.

Push Factor - Agricultural Decline
  • Agricultural decline means a person cannot grow
    as much food on the same amount of land as they
    once could. Over time land becomes less fertile
    and people have to move.

11
Push Factor - Conflict
  • People flee from wars. These people are known as
    refugees. There are many refugee camps in Africa
    due to a long history of civil war in many
    countries.

12
Push Factor - Political Persecution
  • Political persecution means that people are
    punished when they disagree with the government.
    This happens most in dictatorships or communist
    countries. People have migrated from China and
    Cuba because of political persecution.

13
Push Factor - Natural Hazards
  • Droughts
  • Floods
  • Tsunamis
  • Earthquakes
  • Volcanoes

14
Push Factor - Limits on Freedom
  • Communist countries often limit personal freedom.
    People cannot listen to certain music, watch
    certain television shows, or even say things bad
    about the government.

15
Push Factor - Environmental Degradation
  • Deforestation
  • Desertification - An expansion of arid conditions
    into non-arid regions. This is a problem in the
    Sahel, a region near the Sahara Desert in North
    Africa.
