In 2014, birth rates among U.S. women increased by 1 percent from the previous year. At first glance, that bump might not seem so newsworthy, but it is — this is the first time that U.S. birth rates have increased in seven years. The plateau of birth rates since 2007 coincided with the economic recession that began that very same year, so this uptick in births could offer yet another sign of the economy's improvement. The biggest boost in birth rates came from moms in their 30s and early 40s, according to the data published by the CDC's National Center for Health Statistics.
