The assumption that religion is something that people stick with is dubious, though. In the absence of coercion people will tend to abandon religion. Look at what's happening to Christianity in the US.
As a country we were over 50% secular 30 years ago, the last census tells over 90% declared to be religious (census is wrong, but how wrong?).
