Some consider it genital mutilation and some consider it to be preventative medicine, but the popularity of the procedure has its ups and downs. I don't really have a strong opinion one way or the other, but I do find this interesting from a public health policy perspective.
The rate of in-hospital circumcision rose from 48.3% in 1988-91 to 61.1% in 1997-2000, the CDC reports. To gauge current rates of circumcision, the researchers looked at numbers from three large, independent data sources, all of which collect discharge data on inpatient hospitalizations. Every data set showed a decline. For example, the 1999-2010 National Hospital Discharge Survey showed that fewer than 12 million of nearly 20 million newborn boys were circumcised over the past decade. The survey showed that the rate of in-hospital circumcisions dropped from 62.5% in 1999 to 56.9% in 2008.
