Demography

Population or Arithmetic Density

Ecumene or Non-Ecumene

Carrying Capacity

Population Distribution

Migration – Intercontinental, interregional, rural to urban

Crude Birth Rate – babies born per 1000 people

Crude Death Rate – babies died per 1000 people

Rate of natural Increase (NIR or RNI) = CBR-CDR/10

Doubling Time

Population Momentum

Zero Population Growth: BR + Immigration = DR + Emmigration

Population Pyramid or Age-Sex Pyramid

Dependency ratio

Total Fertility Rate

Demographic Transition Model

Stage 1 – BR & DR high

Stage 2 – BR high, DR drops (high population growth)

Stage 3 – BR falls (population growth slows)

Stage 4 – Low BR & DR (NIR is low or decreasing)
