The birth rate for teens 15 to 19 years old decreased 9 percent. It was the largest single year decline since 1946-1947, the report states. The overall rate has decreased 44 percent from 1991.

Bill Albert, spokesman for the National Campaign to Prevent Teen and Unplanned Pregnancy, told Reuters that it was a dramatic one-year decrease. He said an increase in school sex education and the slow economy may be primary reasons for the decrease.

Albert also attributed the decline to reality television shows about teen pregnancy, saying they give teens a “sobering look at the reality of being a parent.”

Birth rates for women in their 20s and 30s dropped in 2010, also. The only age group with an increase in births was women in their 40s.

The CDC website states that teen pregnancy is a priority due to its high economic, social and health costs on teen parents and their families. U.S. teen birth rates are nearly 9 times higher than in most other developed countries.

The website also states that Hispanic and black teen girls are 2-3 times more likely to give birth than white teen girls. Approximately 50 percent of teen mothers get their high school diploma by the age of 22 compared with 90 percent of teens that aren’t mothers.
