Pew Research Center for the People & the Press. May 7, 2013.
The public’s views of whether Islam is more likely than other religions to encourage violence have changed little in the aftermath of the Boston Marathon bombings. Currently, 42% say Islam is more likely than other religions to encourage violence among its believers, while 46% say Islam does not encourage violence more than other religions. These are similar to opinions about Islam and violence for most of the past decade. But in March 2002, six months after the 9/11 attacks, just 25% said Islam was more likely to encourage violence while 51% disagreed. [Note: contains copyrighted material].

Pew Forum on Religion and Public Life. March 13, 2013.
The percentage of U.S. Catholics who consider themselves “strong” members of the Roman Catholic Church has never been lower than it was in 2012, according to a Pew Research Center analysis of new data from the General Social Survey (GSS). About a quarter (27%) of American Catholics called themselves “strong” Catholics last year, down more than 15 points since the mid-1980s and among the lowest levels seen in the 38 years since strength of religious identity was first measured in the GSS, a long-running national survey carried out by the National Opinion Research Center at the University of Chicago.
