What these counts cover

Affiliations are those reported in Pew’s named list for the incoming 119th Congress. They are a dated observation, not a new survey, and we do not infer religion from names or photographs. 21 serving members are not on that list and are not counted. Pew’s categories are kept as published, so “Protestant” without a denomination is its own row.
