I'm not sure about our local private schools - my DD goes to a high achieving Charter School and we are full but at $400 annually, our fee's are extremely low.
My DS attends our local university and they didn't even open 2 full dorms that were open last year. Also he lives in off campus student housing that last year at this time had a waiting list and this year they have 50 vacancies.
We have IPFW (Indiana/Purdue University Ft Wayne) here and they are building more of the on campus housing. They aren't dorms, but apartments that the students can lease. They have 4-5 building in various stages of constrution, mostly close to completed and they have cleared out enough land that it looks like they could build another 7-9 buildings.
We have family that have kids enrolled in the catholic elem schools here. The largest school, there is no decline in enrollment. A couple of the smaller schools are hanging on by their thumb nails. There was no decline at either of the catholic high schools.
