So says a report in USA Today, here:
As the economy tanked, the average number of births per woman fell 12% from a peak of 2.12 in 2007. Demographic Intelligence projects the rate to hit 1.87 this year and 1.86 next year — the lowest since 1987. ... The U.S. fertility rate has been the envy of the developed world because it has remained close to the replacement rate of 2.1 (the number of children each woman must have to maintain current population) for more than 20 years.
