A recent study from the National Center for Health Statistics reports that teen birth rates in the U.S. have hit a record low: “31.3 births per 1,000 girls and women” between the ages of 15 and 19. These rates have been going down for a number of years, but this represents an eight percent decline in a single year (2010 to 2011), which is pretty impressive. Overall, teen birth rates have fallen 49 percent since 1991.
While the study just looks at the numbers, and not factors that may have led to the drop, researchers have suggested several reasons that could be contributing to the decline. Teens are delaying the age at which they begin having sex, and it is becoming more common for teenagers to use contraception—including methods that were once recommended primarily for older women, such as the IUD.
