“Educated people have fewer kids. Few demographic laws are more strictly enforced. This law doesn’t just fit the modern United States. High-education countries are less fertile than low-education countries, and countries’ fertility erodes as education advances, at least since 1900. Fertility gaps are big: Averaging over the world, low-education women outbreed high-education women by about one-third. Nation-by-nation, disparities of a full child or more are common. In principle, education could be a mask for income, intelligence, status, democratization, or modernization. When statistically challenged, though, education stays strong.” (08/20/25)
