demographic transition
a generalised description of the changing pattern of mortality, fertility and growth rates as societies move from one demographic system to another
Demographic Transition: Stage 1
high birth rate and a high death rate - no natural increase
Demographic Transition: Stage 2
rapid decrease in a country’s death rate while the birth rate remains high - very high natural increase
Demographic Transition: Stage 3
death rates are low and birth rates decrease - natural increase is low
Demographic Transition: Stage 4
mortality and birth rates are low - no natural increase

EG Ravenstein’s Laws of Migration
1) Most Migrants Go Only Short Distances
2) Migration Goes by Steps (Step-by-Step)
3) Long-Distance Migrants Prefer to Go to Big Cities
4) Migration Flows Produce Counter-Flows
5) People from Urban Areas Migrate Less than Rural People
internal migration pattern in the US
the population has moved westward and from rural to urban areas as places become increasingly industrialized
net out-migration
the number of emigrants exceeds the immigrants
