"The influence and significance of Catholic and Protestant faith communities is dwindling rapidly."

As per the NHS, religiosity (>10 visits to religious institution in last year) fell like a stone, on a generational basis:

Great Generation: 72%
Boomers: 41%
Gen X: 27%
Millennials: 17%

Every time I post those numbers, you see the same accounts disagreeing, but in the end all the disagreement in the world doesn't change those numbers. I used to sit on a board that discussed as a group how to deal with older church buildings going to seed, because my city has the highest concentration of churches in Canada. The religious leaders also on that board chose the 'head in sand' route, and I left in frustration because they clearly didn't want a reasonable solution to the problem.  Fast forward 9 years, and now we've got parishes begging the city to subsidize 'heritage' buildings they cannot afford to maintain themselves.
