The First Amendment Center published the results of its 2010 survey of 1003 adult Americans and found that 53% of them agreed with the statement, "The U.S. Constitution establishes a Christian nation." The survey compared 2008 survey results with 2010 statistics and found:
|Did Not Know or Did Not Answer||7%||6%|
Source: First Amendment Center (full survey – PDF). (Note: One of the 2008 percentages may be off by 1% since the tally is 101%, but we did not change the original data to make the numbers add up.)
Only 26% strongly disagreed that the Constitution created a "Christian nation." The survey did not reveal why some "mildly" disagreed with the statement.
Ironically, 66% felt that the First Amendment created a clear separation of church and state. Further reading: Majority of Americans support expressions of faith in the public.
