Fertility rates in the United States are continuing their decades-long decline, due in large part to a steep slide in teenage pregnancies down to historic lows, according to a new government report released Thursday. The report only examined the trajectory of pregnancy rates through 2009, stopping there because more recent data on abortions is not available yet. But newer statistics on birth rates suggest the decline is continuing, though not as quickly as it did in recent years when the recession accelerated trends well underway.
