Teenage pregnancy in the United States
Although there is a noticeable decline in U.S. teen pregnancy, the current rate is still 2-4 times more than in Canada, France, Great Britain, and Sweden. The biggest difference in the rate of pregnancies in the United States compared to the other countries is that in America there is a very high unintended pregnancy rate. This unintended pregnancy rate is higher than the total teenage pregnancy rate in all of the four countries.
In 2010 there was a rate of 57 pregnancies per 1,000 women aged 15–19. Most of those women reported that it was an unplanned pregnancy. This shows a 15% drop in pregnancies from 2008 to 2010. There is a huge decline in adolescent pregnancy for the nation as a whole. The cause of these declines are from abstaining from sex or better use of contraceptives. Birth rates among younger teens ages 15–17 have also fallen faster – dropping by 50%, compared with a 39% decline among older teens ages 18 and 19. Researchers have concluded that these declines stem from improvement in use of contraceptives.
