In one survey, newborn male circumcision rates fell to 56.9 percent in 2008 from 62.9 percent in 1999. In another, rates of circumcision fell to 54.7 percent in 2010 from 58.4 percent in 2001. In a third, rates fell to 56.3 percent in 2008 from 63.5 percent in 1999.
Circumcision is a ritual obligation for infant Jewish boys, and is also a common rite among Muslims, who account for the largest share of circumcised men worldwide.
The wider U.S. population adopted the practice due to potential health benefits, but those advantages have become the subject of debate, including a recent effort to ban circumcision in San Francisco.
Medicaid coverage may be one factor. A recent study found circumcision rates were 24 percentage points higher in states in which it was routinely paid for compared with hospitals in states that do not cover the procedure.
As of 2009, Medicaid paid for circumcision in 33 U.S. states.
