The U.S. birth rate plunged last year to a record low, with the decline being led by immigrant women hit hard by the recession, according to a study released Thursday by the Pew Research Center.
The overall birth rate declined by 8 percent between 2007 and 2010, with a decrease of 6 percent among U.S.-born women and 14 percent among foreign-born women. The decline for Mexican immigrant women was more extreme, at 23 percent. The overall birth rate is now at its lowest since 1920, the earliest year with reliable records.
The decline could have far-reaching implications for U.S. economic and social policy. A continuing decline would challenge long-held assumptions that births to immigrants will help maintain the U.S. population and provide the taxpaying work force needed to support the aging baby boomer generation.
The U.S. birth rate — 63.2 births per 1,000 women of child-bearing age — has fallen to just over half of what it was at its peak in 1957. The rate among foreign-born women also had been declining in recent decades, according to the report, though more slowly.
