Fertility Rate by Country — 2023 World Rankings

The total fertility rate (TFR) estimates the average number of children a woman would bear over her lifetime if current age-specific fertility rates persisted. A TFR of 2.1 is considered "replacement level" — the rate needed to maintain a stable population without migration. Below that, populations shrink over time; above it, they grow. The data comes from the World Bank using UN Population Division estimates.

The global fertility transition is one of the most consequential demographic shifts in human history. In 1960, the average woman worldwide had 5 children; today the global TFR is approximately 2.3 and falling. Every major world region has experienced fertility decline, including sub-Saharan Africa where rates have dropped from 6.7 to about 4.5. The drivers are consistent across cultures: female education, urbanization, access to contraception, declining child mortality (parents need fewer births to achieve desired family size), and the economic shift from agricultural to service economies.

The most immediate consequence of below-replacement fertility is population aging. South Korea's TFR has fallen below 0.8 — the lowest ever recorded for any country — creating an acute demographic crisis with a rapidly shrinking workforce and exploding elderly dependency ratio. Japan, Italy, Spain, and much of Eastern Europe face similar trajectories. At the other extreme, Niger's TFR above 6.5 means its population will roughly triple by 2050, creating enormous pressure on education, employment, and resources. Fertility data is crucial for long-term economic planning: today's birth rates determine tomorrow's labor force, consumer markets, and pension obligations.
