Key Idea: Topic 1.1 is about where people live, why, and how a country's wealth shapes its population. It pulls together two ideas: 1.1.1 — distribution & density: the physical factors (climate, relief, water, soils) and human factors (economy, history, politics) that make population spread so uneven across the world. 1.1.2 — development & fertility: how rising economic development drives the demographic transition — birth rates fall, the population ages, and for a window a country can enjoy a demographic dividend. This is core content, examined on Paper 2 — a data-response read off a population map or graph, a short structured Explain, and it can feed the extended-response essay.
🗺️ 1.1.1 — Where people live, and why
Population is spread unevenly: a few areas are densely populated, most of the land is sparsely populated. The factors split into physical (the natural environment) and human (people's decisions). The skill examiners test is reading a choropleth map or bar/line graph of density, then describing the pattern and explaining it with these factors.
Tip: For a map/graph question, describe the pattern first — name the highest and lowest areas, quote a figure with units (people/km²), and note any clustering (e.g. along coasts/rivers). Then explain it with one physical and one human factor.
📈 1.1.2 — Development, fertility & the demographic dividend
As a country develops economically, its birth and death rates fall — the demographic transition. The age structure shifts from a wide-based pyramid (many children) to a more column-shaped one (an ageing population).
When the bulge of a fast-grown population reaches working age while birth rates have already fallen, a country has many workers and few dependants for a few decades. Invested well (jobs, education, health), this powers rapid economic growth — but the window closes as that bulge later ages.

Exam Tips
- For a population map/graph: DESCRIBE first (highest, lowest, a figure with units, any clustering), THEN explain with one physical + one human factor.
- Keep density (people/km²) and distribution (the pattern) separate — examiners penalise mixing them.
- Link development to fertility through FEMALE EDUCATION and women in work — the single strongest driver of falling birth rates.
- Replacement-level fertility ≈ 2.1. Below it, a population ages and can decline without migration.
- The demographic dividend is a TEMPORARY window — many workers, few dependants — that only pays off if jobs, education and health are in place.
- On the [10] Examine/Evaluate, always weigh a counter (culture, policy, time-lag) and finish with a clear judgement.
