From Pew’s fascinating report on the religious composition of the 113th Congress:

About one-in-five U.S. adults describe themselves as atheist, agnostic or “nothing in particular” – a group sometimes collectively called the “nones.” But only one member of the new Congress, Kyrsten Sinema (D-Ariz.), is religiously unaffiliated, according to information gathered by CQ Roll Call. Sinema is the first member of Congress to publicly describe her religion as “none,” though 10 other members of the 113th Congress (about 2%) do not specify a religious affiliation, up from six members (about 1%) of the previous Congress. This is about the same as the percentage of U.S. adults in Pew Research Center surveys who say that they don’t know, or refuse to specify, their faith (about 2%).

The numbers here caught my eye, not because of the disparity between non-believers in the general population and in Congress, but because I was surprised so many members actually admitted to it.
