How many chapels get Sunday and Holy Day Mass? How many have a resident priest? How many have a school? How many would best be described as a "mission Chapel" where the entire property is pretty much a ghost town except for 3 hours on Sunday morning? How many Masses per month at these "chapels"? A chapel with 30 Masses a month (or more) is certainly a bigger deal than a (mission) chapel that gets Mass once or twice a month, or even 4 times a month.
How many of these "chapels" have a website or contact information of any kind? How many have a number where you can reach a priest for Extreme Unction? How many have a regular schedule for Confession?
