Maps and explorers

The charts most people come here for — regional fertility maps, census maps, where the births are, and the fertility decomposition — plus the rest of the catalogue.

  • People

    Why birthrates matter

    Age structure, pensions, schools, and coalitions — then generate a country briefing you can send to someone who has to act on it.

  • Maps

    Regional fertility maps

    Total fertility by state, province, and country — India, Pakistan, Nigeria, Brazil, Colombia, Indonesia, Iran, Europe (NUTS 2), Africa, the Caribbean, and dozens of other official maps.

  • Maps

    Census maps

    Ethnicity, ancestry, race, and country of birth from national censuses — the UK, Denmark, Germany, Russia, the United States, and the rest of Europe.

  • 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.

  • Population

    Share of world population & births

    China, India, Nigeria and others as % of world people and babies, 1950–2100 — with UN medium forecast.

  • Population

    World population growth map

    Annual % change by country on a scrubable timeline — who is growing, who is shrinking.

  • Population

    India as population dots

    WorldPop 2025 grid as glowing dots — zoom in and tiles stream from a single PMTiles archive.

  • Population

    Europe: who grew, who shrank

    GHSL 2000→2025 settlement change — green growth, pink decline, gray empty.

  • Population

    Compare regions yourself

    Paint provinces into groups, sum their populations, and download a social-ready image.

  • Population

    Population rankings

    Most populous countries, fastest growth, density, dependency, rural share, and urban growth.

  • Population

    Workers vs retirees

    Working-age and 65+ headcounts — compare countries through 2060.

  • Fertility

    Fertility by race, origin & income

    U.S. TFR by race since 1980, Austria national-origin and Kosovo ethnicity tables, Bolivian projections, and a GDP–fertility scatter.

  • Fertility

    Fertility by education and income

    DHS TFR by schooling and wealth quintile, U.S. TFR by educational attainment, and why language spoken at home has no official U.S. fertility table.

  • Fertility

    Many mothers, or large families?

    The same total fertility rate can mean most women become mothers, or that a smaller group of mothers have larger families.

  • Fertility

    Fertility since 1800

    Total fertility for most countries back to the nineteenth century — Human Fertility Database, UN WPP, and Gapminder reconstructions, then World Bank from 1960.

  • Fertility

    World fertility

    Interactive timeline, TFR since 1800, 2026 nowcast, country rankings, and the biggest movers.

  • People

    Cities

    Population, fertility, and foreign-born share for metropolitan areas worldwide.

  • Tools

    Country briefings

    A memo you can forward: fertility, neighbors, workers versus retirees, and whether family policy has moved TFR elsewhere. Every country on the site.

    Compare countries

    Side-by-side fertility, population, migration, and GDP for any pair of countries.
