Population Growth

The Issue:
Up until the Great Recession, the number of babies born per woman in the United States had been quite stable for the previous three decades. The birth rate fluctuated within a relatively narrow range, often along with economic conditions, with fewer babies born during lean times and with births recovering when economic growth was stronger. However, the U.S. birth rate has fallen precipitously since the 2007 Great Recession, with no signs of reversing. This decline cannot be explained by demographic, economic, or policy changes. It is reflective of lower childbearing rates across successive cohorts.
The U.S. birth rate has fallen by 20% since 2007. This decline cannot be explained by demographic, economic, or policy changes.
The Facts:
- The Great Recession disrupted a stable period in birth rates. For the almost three decades between 1980 and 2007, the U.S. birth rate hovered between 65 and 70 births per 1,000 women between the ages of 15 and 44. The birth rate followed a predictable pro-cyclical pattern, falling during economic downturns and recovering when the economy improves. But something changed around the time of the Great Recession; the birth rate fell precipitously, and it did not recover when the economy improved. Rather, the U.S. birth rate has continued a steady descent. As of 2020, the U.S. birth rate was 55.8 births per 1,000 women between the ages of 15 and 44, a decline of almost 20 percent from the rate of 69.3 in 2007.
- The decline in births cannot readily be explained by changing population composition. The sustained decline in U.S. births since 2007 has been driven by declining births among many demographic groups, rather than by changes in population composition. Births have fallen among women in their early 20s, late 20s, and teens (in fact, the teen birth rate in the U.S. has been falling steadily since the mid-1990s). Births have fallen among white women, Black women, and Hispanic women, with the largest declines among Hispanic women. Births have also fallen among women with and without college degrees and among both married and unmarried women. The population of U.S. women of childbearing age has actually shifted toward groups that tend to have higher birth rates, not lower birth rates, with the exception of a rising share of women of childbearing age being unmarried.
- No obvious policy or economic factor can explain much of the decline. The onset of the Great Recession clearly played a role in the early stages of the decline. Beyond that, it is difficult to identify any policy or economic factor that can statistically account for the continued decline. Casual observers have suggested that a variety of potential factors are responsible for the decline, including greater take-up of highly effective contraception, the h
