The USA rates have gone down since the heydays of circumcision. But I do not think there are a truly accurate number, and it is also possible that it varies from one area to another. In a area with high hispanic population, the rates would be much lower, and white parents told the rate is down to 30% so they may leave their son intact. But in anothera rea, the rate may still be above 80%.
I read some article a couple years back about texas. They surveyed a high school in a white area and it was 85% cut. Those would have been about 12-15 year olds. ut ovrall texas would have a lower rate because of hispanic population.
Obviously, the anti circers love the incomplete statistics because it gives them a winning feeling so they happyly republish those studies.
However, what I'd like to see is a study done after 1 month of birth that shows how many are still uncut, how many were cut at hospital during the birthing, how many cut at clinic after birth, how many returned to hospital to get it done etc. This would give a better idea and also provide greater trust that the total statistic reflects the true story, just just partial counting of one type of circumcison (done at hospital as part of birth).
