We generally have full masses on Sunday (about 1/3 of actual registered parishioners) and weekly masses except Tuesday, and then a Communion service on Tuesday. There are 10 churches within 10-20 miles.
With the retirement of priests, parishes are being grouped to probably share services in the future.
In the Milwaukee Archdiocese, we currently have 182 active priests for 204 parishes. Some parishes a covered by priest from another parish or a retired priest. 26% of the population is Catholic but they all do not attend Sunday Mass. It is real busy at Christmas and Easter.
As an aside, we tried to attend Christmas Mass in Connecticut with my elderly father in law and arrived 45 minutes early and the Pastor said there was no room at the inn (church) and told us to leave.
