New cards
2

Cohort

Population of various age categories in an age-sex population pyramids.

New cards
3

Demographic momentum

this is the tendency for growing population to continue growing after a fertility decline because of their young age distribution.

Demographic Regions

Cape Verde is in Stage 2 (High Growth), Chile is in Stage 3 (Moderate Growth), and Denmark is in Stage 4 (Low Growth). This is important because it shows how different parts of the world are in different stages of the demographic transition.

New cards
5

Demographic Transition model

Has 4 steps. Stage 1 is low growth (low stationary), Stage 2 is High Growth (early expanding), Stage 3 is Moderate Growth (late expanding), and Stage 4 is Low Growth (low stationary), and Stage 5 although not officially a stage is a possible stage that includes zero or negative population growth. This is important because this is the way our country and others countries around the world are transformed from a less developed country to a more developed country.
