Population is a stock; growth is a flow. Fertility, mortality, and net migration all move the total, but age structure decides how many of those people are children, workers, or of retirement age. Two countries with the same headcount can face opposite pressures if one is a youth bulge and the other is a rectangle with a heavy top.
This hub is a directory of explorers, not a single dump of every chart. Use share-of-world series for who will hold the next generation of births, the growth map for where stock is rising or falling, and the workers–retirees view for the pension arithmetic. Country profiles still carry the full national time series and UN projection variants.
Figures come from World Bank and UN World Population Prospects unless a page names a national office. Projections are scenarios — medium is the conventional reference, not a promise. Definitions: glossary.
Charts
Country shares of world people and babies — history and UN forecast.
Population
Share of world population & births
China, India, Nigeria and others as % of world people and babies, 1950–2100 — with UN medium forecast.
Population
Where the births are
Share of a region's residents, and share of its babies — country by country. A younger country can punch above its population.

What this page measures
- Total Populationpeople
- Total resident population, all ages and both sexes. Source: World Bank Open Data.
- Population Growth% annual
- Annual percentage change in total population, combining births, deaths, and net migration. A country can grow while births fall, if migration more than compensates. Source: World Bank Open Data.
- Population Ages 0–14 (% of total)% of population
- Share of the population aged 0–14. Used to anchor the current age structure for projections. Source: World Bank Open Data.
- Population Ages 15–64 (% of total)% of population
- Share of the population of working age (15–64). Used to anchor the current age structure for projections. Source: World Bank Open Data.
- Population Ages 65+ (% of total)% of population
- Share of the population aged 65 and over. Used to anchor the current age structure for projections. Source: World Bank Open Data.
- Urban Population% of total
- Share of the population living in urban areas (%). Source: World Bank Open Data.
- Rural Population (% of total)% of total
- Share of people living outside areas classified as urban — the complement of the urban share. Each country sets its own urban definition, so this reads best within a country over time rather than across borders. Source: World Bank Open Data.
- Urban Population Growth% annual
- Annual change in the population living in urban areas. Combines natural increase in cities, migration from the countryside, and places being reclassified as urban — the third can move the series without anyone moving house. Source: World Bank Open Data.
- Population Densitypeople per sq km
- People per square kilometre of land area. Land area includes desert, mountain and ice, so national density says little about how crowded the inhabited parts of a country actually are. Source: World Bank Open Data.
- Age Dependency Ratio% of working-age population
- People under 15 and over 64 per 100 people of working age. A high ratio can mean many children or many pensioners — opposite fiscal situations — so read it alongside the age-structure shares. Source: World Bank Open Data.
- Female Share of Population% of population
- Women as a share of the total population. Departures from roughly 50% reflect sex selection at birth, the gap between male and female mortality, and heavily sex-imbalanced labour migration. Source: World Bank Open Data.
- Figures beyond the current year are UN projections conditional on assumptions, not forecasts.
Definitions for every indicator are listed in the glossary, and collection methods in the methodology.
