What is the demographic transition model?Show answer
The demographic transition model is a generalised model of how a country's birth rate, death rate and population growth change as it develops. It is usually shown in stages:
What are population pyramids?Show answer
A population pyramid is a back-to-back bar graph showing the proportion of males and females in each age group. Its shape reveals the population's structure and history:
What are dependency ratios?Show answer
The dependency ratio compares the dependent population (children under 15 and adults 65 and over) with the working-age population (15 to 64). A high youth dependency ratio strains education and family resources; a high aged dependency ratio strains pensions, health care and the workforce. The ratio matters because it links population structure to real economic pressure. A youthful country must invest in schooling and jobs; an ageing country faces a shrinking workforce supporting more retirees.
What is limitations of the model?Show answer
The model is a useful generalisation, not a rule. It was based on European experience and does not perfectly predict every country. Migration, government policy, disease and culture all alter the path. Some countries pass through stages faster than others, and stage five was not in the original model.
