In April 2013, the Centers for Disease Control and Prevention (CDC) reported that nearly one in five teen births is a repeat birth—meaning that it's at least the second birth for the teenage mother. Although the repeat teen birth rate in the United States declined by more than 6 percent between 2007 and 2010, it remains high—especially in American Indian/Alaskan Natives (21.6 percent), Hispanics (20.9 percent), and non-Hispanic African Americans (20.4 percent). In Caucasian teens, the repeat birth rate is 14.8 percent.
