- Crude birth rateRight answer
- Total fertility rate
- Crude death rate
- Natural increase rate
What this set covers
Birth, death and fertility rates come first here, along with natural increase, dependency ratio, the demographic transition model and Lee's migration ideas such as intervening obstacles, remittances and brain drain.
- Common mix-up
- Students often mix up crude birth rate and total fertility rate: one counts births per 1,000 people, the other is the average number of children per woman.
- Revision tip
- Work through the natural increase and dependency ratio calculations by hand, then say aloud which stage of the demographic transition model fits each result.
