Maps and explorers
Maps
- Regional fertility mapsTotal 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.
- Census mapsEthnicity, ancestry, race, and country of birth from national censuses — the UK, Denmark, Germany, Russia, the United States, and the rest of Europe.
- World in 10 millionThe whole planet as zones of about ten million people each — after Anita Chen.
Fertility
- Fertility by race, origin & incomeU.S. TFR by race since 1980, Austria national-origin and Kosovo ethnicity tables, Bolivian projections, and a GDP–fertility scatter.
- Fertility by education and incomeSchooling and wealth in every DHS survey since 1985, Europe by education, and U.S. births and completed families by degree.
- 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.
Population
- Where the births areShare of a region's residents, and share of its babies — country by country. A younger country can punch above its population.
- Share of world population & birthsChina, India, Nigeria and others as % of world people and babies, 1950–2100 — with UN medium forecast.
- World population growth mapAnnual % change by country on a scrubable timeline — who is growing, who is shrinking.
People
- Why birthrates matterAge structure, pensions, schools, and coalitions — then generate a country briefing you can send to someone who has to act on it.
- What's the solution?A pronatal culture — children treated as a public good, and said so out loud. Israel, Mongolia, Kazakhstan, and Georgia are the record.
- Crime by originNatives and immigrants in official crime figures. Rank origin groups and compare countries.
