The U.S. birthrate edged up slightly for the first time since the recession of 2008 led American families of childbearing age to defer having children. There were 62.9 births for every 1000 women of childbearing age in 2014, increasing from 62.5 in 2013, according to the Centers for Disease Control and Prevention. The total fertility rate also increased slightly to 1.862 children in 2014 from 1.858 in 2013. This is below the rate of 2.1 children a woman would have over her lifetime to keep population at the same level, without immigration. Kenneth Johnson, a demographer at the University of New Hampshire, estimates about 2.3 million more births if the 2008 recession had not led women to defer having babies. In 2014 U.S. births increased 1.4% to 3.99 million children from 3.93 million in 2013. Women over 30 and better educated are showing a larger increase in births.
