I took this Newsweek poll online a few days ago, and now overall results are tabulated. There was an earlier, phone version of the poll, done by Beliefnet and Newsweek, which reached far fewer people. Both show some interesting results. You can read about the earlier version here. Unfortunately, results of the earlier poll are tabulated in a more effective way so it's possible to get a little more information about who responded how -- but the statistics aren't as good.
Here are some interesting points:
When asked, "Can a good person who isn't of your religious faith go to heaven or attain salvation, or not?" 79% of people said yes, including 68% of professing evangelical protestants, 83% of professing non-evangelical protestants, 91% of Roman Catholics, and 79% of non-Christians (earlier poll). The later, online poll had significantly fewer people saying yes, and results aren't broken down by religious identification.
The polls found 85% (telephone) and 71% (online) of people identifying themselves as Christian. Yet 55% (telephone) and 51% (online) of people attend worship services once or twice a month or less. And 55% (telephone) and 52% (online) of people read "the Bible, Koran, or some other sacred text" less than once or twice a month. (On the flip side, I guess it's reassuring that 40-some percent of people do these things more than once or twice a month).
[UPDATE: It's worth also noting this comment in this Newsweek article:
Of 1,004 respondents to the NEWSWEEK/Beliefnet Poll, 45 percent said they attend worship services weekly, virtually identical to the figure (44 percent) in a Gallup poll cited by Time in 1966. Then as now, however, there is probably a fair amount of wishful thinking in those figures; researchers who have done actual head counts in churches think the figure is probably more like 20 percent.]
Most people (70-80%) also believe (according to these polls) that God created the universe.
