Questions

location. A pull factor induces
people to move to a new location.
Push Factor - Overpopulation
 People often leave areas that are
heavily populated.

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.

people are known as refugees.
There are many refugee camps in
Africa due to a long history of civil
war in many countries.

environmental or cultural feature
that hinders someone from
migration. This means that people
don’t always go to their desired
destination.
Intervening Obstacles
In the past, intervening obstacles
were primarily environmental.
Before the invention of modern
transportation systems such as
railroads people migrated by horse
or on foot. What type of obstacles
might hinder their progress?
Where do people migrate to?

most immigrants in the world.
Countries such as the United
