The standard explanation for the global decline in birth rates is that as women become more educated, they have fewer children. Cross-sectional data comparing different countries supports this, but looking at a single country's progress over time tells a different story. Within individual nations, education and labor participation are often positively related to fertility as families gain more resources. The common recipe for why populations shrink is a statistical illusion created by comparing vastly different societies. Understanding local fertility requires looking at specific economic conditions rather than broad global trends.
From the abstract
Global fertility has declined from 5.4 children per woman in 1960 to 2.3 in 2023, with many major economies reaching record lows far below replacement. This decline has occurred across countries with vastly different levels of income, institutions, and cultural backgrounds, challenging explanations based on these traditional variables. Using a panel of 237 countries from 1950 to 2023, I show that widely documented cross-sectional relationships do not carry over to within-country changes over tim
