A government report shows teen pregnancies fell again last year, to another historic low.
Brady Hamilton, the lead author of the new report from the Centers for Disease Control and Prevention, said "the continued decline is really quite amazing."
Last year, the birth rate for U.S. teens dropped 8 percent. Rates have been falling since 1991, and this marks yet another new low.
Experts cite a range of factors, including less sex, positive peer influence and more consistent use of birth control.
