From 4.5 Million to 8 Billion: How Earth’s Population Changed Over 12,000 Years

China’s Fertility Crisis: From World’s Most Populous to Demographic Collapse
China’s fertility rate has plunged to 1.0 child per woman in 2023, with dramatic provincial variations from 1.68 in Guizhou to 0.52 in Heilongjiang.

Where Europe’s 15–19-Year-Olds Have Two Native-Born Parents
The Eurostat-based map highlights how migration has reshaped Europe’s families. Many Central and Eastern European countries still have over 90% of teens with two native-born parents, while Western and Northern nations show far lower shares due to long histories of immigration and mobility.
