Mississippi Home to Most Teen Births 55 out of every 1K girls ages 15 to 19 have a baby there By Kate Seamons, Newser Staff Posted Apr 10, 2012 9:07 AM CDT 50 comments Comments Mississippi teen birth rate is 55 out of every 1K girls ages 15 to 19. (?Lars Plougmann) (Newser) – Mississippi continues its No. 1 streak: It takes top honors as America's most religious and fattest state, and now it's also claimed the crown when it comes to teen births. The highest rate was once more observed in Mississippi, according to a new government report, but the good news is that teen births slipped overall from 2007 to 2010, with only three states—Montana, North Dakota, and West Virginia—staying about the same. Among girls ages 15 to 19, the rate is now 34 per 1,000, the lowest it has been since record keeping began in 1940. Mississippi occupies one extreme, with a rate of 55, while New Hampshire brings up the rear with just 16 teen births per 1,000. The rate has sunk 44% since 1991, leading to 3.4 million fewer babies born since. Experts attribute the drop to the economy and pregnancy prevention efforts, reports the AP.
