I'd guess about half of that identify as Christian because it's socially unacceptable to be agnostic. Church communities have more uses than simple religious worship. Ask any salesman.

That's much less an issue now than 50 years ago though, which is what's important when talking about a relative decline. It was much less socially acceptable to identify as agnostic in 1960 than it is today.
My dad was a music director and assistant pastor. He worked about 5 days a week, and also had another job on the side. Choir practice, church functions and services, preparing sermons, visiting sick church members, counseling members, and doing charity work add up to a good bit of time.
