From the Wall Street Journal:
The number of babies born in the U.S. last year fell to a 32-year low, deepening a fertility slump that is reshaping America's future workforce.
About 3.79 million babies were born in the U.S. in 2018, according to provisional data from the Centers for Disease Control and Prevention's National Center for Health Statistics. That was a 2% decline from the previous year and marked the fourth year in a row that the number fell. The general fertility rate – the number of births per 1,000 women ages 15 to 44 – fell to 59.0, the lowest since the start of federal record-keeping.
With the latest decline, births in the U.S. have fallen in 10 of the last 11 years since peaking in 2007, just before the recession. Many demographers believed that births would rebound as the economy recovered, but that trend hasn't materialized.
