SAN ANTONIO - The teen birth rate in the United States has fallen for the third straight year. Mississippi has the highest rate, with 55 teen births per 1,000 girls. New Hampshire had the lowest rate at 16 per 1,000. Texas has the fourth highest teen pregnancy rate in the nation, with 52 per 1,000 thousand girls aged 15-19 giving birth.
The Centers for Disease Control and Prevention reports the 2010 rate for teenage moms was the lowest point since record keeping began in 1940.
Since 1991, the overall teen rate has dropped by 44 percent.
Researchers say the decline is partly due to the economy and pregnancy prevention efforts.
