There is no particular reason to assume that attendance rates are the same across denominations of Christianity in the United States. To examine that, I divided the Christians in the GSS into three categories: Evangelical Protestant, Mainline Protestant, and Catholic. (A fourth group, Black Protestant, did not have enough members to analyze here). Here are the attendance rates by denomination, in both tabular and graphical form.
Evangelical Mainline Catholic
Weekly 47.1 28.2 35.3
Monthly 18.4 18.6 16.7
Yearly 25.3 40.2 36.5
Never 9.1 12.9 11.4
As shown, there is a lot of variation in church attendance by the type of Christian. Nearly half of all Evangelical Protestants attend church weekly while only about a quarter of Mainline Protestants do. Over a third of the Catholics attend weekly.
