According to research by Jesus Fernandez-Villaverde and Patrick Norrick, as of 2026, global fertility rates are projected to be below the replacement level. This unprecedented decline has not occurred due to wars or pandemics before. The most surprising aspect of this trend is that it primarily affects low- and middle-income countries, particularly among poorer and less educated women.
A single-factor model was applied to data from 236 countries since 1950, and the common factor peaked in 1978. The driving force behind the ongoing decline in fertility is attributed to country-specific trends, with 219 of them being negative and none showing signs of stabilization. Despite various commonly cited mechanisms, none can explain this pattern. The authors propose a conjecture: modernity itself, which makes a third child expensive and childlessness cheap, is the primary reason for this change.
The transition from one child to two, or two to three, requires significant shifts in economic conditions. However, once fertility rates fall below a certain point, they are unlikely to rise back to the replacement level of 2.1. The main economic consequence of this shrinking world is slow growth. While the authors briefly mention birth control, they emphasize that its actual availability and impact are more complex than superficial accounts might suggest.
