UNIT 2: POPULATION AND SETTLEMENT

Population and settlement power point



Population pyramids show the structure of the population. A high base reflects the high birth rate, and a narrower base shows a decline in the birth rate. Here you can see the evolution of China and Europe  in their population pyramids from 1950 to 2040. Initially the base was wider but then the base becomes narrower and therefore life expectancy grows.
