What percentage of doctors are atheist?

The proportion of atheist physicians varies, and there are differing estimates on the matter. One study conducted by the Pew Research Center in 2009 reported that about 34% of physicians in the United States identified as atheists or agnostics. Other estimates have ranged from 20% to 40%. However, it's important to note that these estimates may be influenced by a number of factors such as the geographic region, methodology used, and time frame.
