Highlights from the report include: 9% of U.S. adults say they don't believe in God up from 5% in 2007. Of the 89% who say they do believe in God or a universal spirit - only 63% do so with absolute certainty (down from 71% in 2007). The "nones" are now the largest religious group in the Democratic Party with 28% (next largest is Catholic with 21%). In 2007 the nones were 19%, which was equal to Evangelical Protestants, but behind Catholics at 24%. Nones are also gaining in the Republican party - 14% in 2014 compared to 10% in 2007. Of the nones, 61% say they believe in God (down from 70% in 2004); however, most are less than absolutely certain about this.
