Tough economic times may be responsible for America's declining abortion rate, which is at a 10-year low.

The Centers for Disease Control and Prevention (CDC) reported last week that the rate and number of abortions performed in the United States fell by 5 percent in 2009, the most recent year for which data is available. According to the CDC, this represents "the largest single-year decrease" for legal, induced abortions since 2000.
