The Secularization Of America

Frank Newport looks at polling on religion:

... older Americans are relatively more religious than younger Americans because they are old -- a standard pattern, but also it appears because the young people of today are particularly less likely to be religious than was the case for the young people of yesterday.  (This suggests, of course, that as the young people of today age, they will become more religious, but most likely will never be as religious as their parents and grandparents).
