  Somewhere around 5-7% of the 324 million US citizens attend catholic mass weekly:
  
  "From here on Catholics who are parish-connected and who attend Mass with some regularity come into full view. Some 36.5 million Catholics attend Mass at least once a month (i.e., this total includes those who attend more frequently) and 32.8 million are in a household that gives regularly to a parish offertory collection. We must drill down further to specifically focus only on the 17.9 million Catholic weekly Mass attenders (i.e., those attending every week. This is different from the number of Catholics attending in any given week. This total is not shown on the graph and includes approximately 23.1 million individuals on a typical weekend)."
