Population Structures Change Over Time
Akopọ
A single graph can tell you whether a country is young and growing fast or old and shrinking. The population pyramid plots how many people fall into each age group and sex, and its shape reveals a nation's past, present and likely future. A broad base means many children; a top heavy shape means many elderly.
This lesson teaches you to read and interpret population pyramids, to explain why structures change over time, and to weigh the consequences of youthful structures (as in Kenya) and ageing structures (as in Japan), including the population policies countries use in response.
