My catholic church is packed with young people and babies. The catholic schools here in Kentucky are packed.
Increasingly that is the same in Canada, in many communities at least. Not sure about the largest cities.
I am going to assume you are in northern Kentucky and have a tradition of schools that are associated with the church. This is a good draw for the church though many in Cincinnati would like to see the church get out of the school business. The local parish with a school does well in demographics. The adjoining parishes without a school are all filled with gray and few children in attendance.
