Of the 365,000 teens who gave birth in 2010, almost 67,000 (18.3%) have had at least one child before, according to the report from the Centers for Disease Control and Prevention. That’s down from 19.5% in 2007. Most were the teen mom’s second child (86%).

But more teen moms are using birth control, the report says — almost 91% used some form of contraception after having had a baby. But just 22% of those used contraceptive methods considered to be “most effective” — tubal ligation, vasectomy, hormonal implant or intrauterine device (IUD). With those, the report says, the risk of becoming pregnant is less than one pregnancy in 100 users a year. The pill, injectables, the patch and the ring are considered “moderately effective.” …

The highest percentages of repeat teen births were among American Indian/Alaska natives (21.6%), Hispanics (20.9%), and blacks (20.4%). The lowest percentage was among whites (14.8%). Texas had the highest percentage of any state (22%) and New Hampshire had the lowest (10%).
