Question

Based on Document 1, which factor most strongly explains why population density is highest in Eastern China and India?



What does the broad base of the population pyramid for the Democratic Republic of the Congo indicate?



Based on the population pyramid, which age group represents the largest share of the population?

Demographic Dividend.

Answer 1

1) Why population density is highest in Eastern China and India
- The strongest factor is fertile plains with reliable water supplies (major river valleys and alluvial plains such as the Yangtze/Yellow rivers in eastern China and the Ganges/Brahmaputra plain in India). These areas support intensive agriculture, early dense settlement, transport and urbanization, and thus a much higher carrying capacity than mountainous or arid regions.

2) What the broad base of the DRC population pyramid indicates
- A very high birth rate and a large proportion of children (high youth dependency). It signals rapid population growth, a low median age, and heavy current demand for education, health care and other child-focused services.

3) Which age group represents the largest share of the population
- The youngest cohort — children (typically the 0–4 year age group, and more broadly the 0–14 age range) — represents the largest share.

Demographic dividend (brief)
- The demographic dividend is the potential for faster economic growth that can occur when the working‑age population becomes a larger share of the total population (after fertility falls). For the DRC the current broad youth base means there is potential for a future dividend, but it will only materialize if the country achieves lower fertility and invests in education, health (including family planning), job creation, and governance so the large youth cohort can be productively employed. Without those investments, the youth bulge may become an economic and social challenge rather than a payoff.
