Today in class, we read about demographic Transition and Mirgration, on page 22.


demographic transition- A 4 stage system that tracks changes in birthrates and death rates through time as a population urbanizes. For example, if there are more birth rates then death rates, the population increases. Similarly, if there are more deaths then births, the population decreases. If they are about equal, the population stays the same, and it balances out.



Never before in history have there been so many people on the move.
People are leaving developing countries to developed countries- for money & jobs, oe to get away from famine, war, persecution, and environmental destruction.
Most migrants migrate to- Japan, Germany, France, Canada, the united states, Italy, the United Kingdom.People tend to move to cities. The UN officials estimate that 35 million should be considered refugees, people who flee their counry because of well founded fears. Over half of these are in Western Asia and Africa.

Three ways a countries population can change:
migration- people can leave or come from somewhere else
death
birth

push forces-
civil strife
environmental degration
unemployment

pull forces-
better economic opportunity
better health services

immigration- migrating into a country

emigrating- magrating into a county

net migration rate- a statistic that shows whether more people are leaving or entering the country.
