Teenage Birthrates Drop to Record Low April 11, 2012, 2:37 pm In February, the Guttmacher Institute reported that in 2008, the pregnancy rate among teenagers dropped to its lowest point in more than 30 years: only 67.8 pregnancies per 1,000 girls 15 to 19 years old, and even fewer pregnancies for younger girls. Now, the Economix blog reports that new numbers from the Centers for Disease Control and Prevention show that births to teenage mothers are also at a record low: 34.3 births per 1,000 girls 15 to 19 years old in 2010, the lowest rate since the government began keeping track in 1940. The rates vary tremendously from state to state - Economix has a fascinating graph. Go look, and see what other graphic illustrations of the differences among states it reminds you of.
