The number of babies born to girls between the ages of 10 and 14 dropped to a record low in 2016, according to data released Wednesday by the Centers for Disease Control and Prevention.

The number of births dropped to 2,253 in 2016 from 8,529 in 2000. The trend follows that of older teens, between the ages of 15 and 19, for whom birth rates have declined by 57 percent in the same period.
