Here's some interesting highlights I found:
Across the 32-year period from 1979 through 2010, the national rate of newborn circumcision declined 10% overall, from 64.5% to
58.3%. During this time, the overall percentage of newborns circumcised during their birth hospitalization was highest in 1981 at 64.9%, and lowest in 2007 at 55.4%.

Between 1993 and 1999, the rate of male newborn circumcisions increased by 13 percent, from 55.3 to 62.7 percent of male newborn hospital stays. However, between 1999 and 2004, the rate of male newborn circumcisions decreased by 12 percent, from 62.7 to 54.9 percent of male newborn hospital stays. From 2004 to 2009, the rate of male newborn circumcisions remained relatively stable in the range of
55 to 56 percent of male newborns in the hospital.

There seems to be a lack of any recent data...these are a decade+ old and rates could've gone in any direction up or down! Odd that there isn't any scientific orgs measuring nowadays.
Some other trends that were noted:
- lower rates in big urban centers
- lower rates in uninsured/medicaid births
- lower rates in recent immigrant populations
- lowest rate in CA at the state level
- highest rate in upper midwest
- highest rates for non-hispanic whites (high 80%!)
