Population Structures Change Over Time
Muhtasari
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.
Malengo
- Factors influencing population structures: natural increase and net migration.
- The causes and impacts of youthful and ageing population structures, and an evaluation of their impacts.
- One detailed specific example of a named country to include: • reasons for population growth or decline • the impacts of a population policy (pro or anti-natalist).
