The differences in charity between secular and religious people are dramatic

Religious people are 25 percentage points more likely than secularists to donate money (91 percent to 66 percent) and 23 points more likely to volunteer time (67 percent to 44 percent).

And, consistent with the findings of other writers, these data show that practicing a religion is more important than the actual religion itself in predicting charitable behavior. For example, among those who attend worship services regularly, 92 percent of Protestants give charitably, compared with 91 percent of Catholics, 91 percent of Jews, and 89 percent from other religions.

Socioeconomically, the religious and secular groups are similar in some ways and different in others. For example, there is little difference between the groups in income (both have average household incomes around $49,000) or education level (20 percent of each group holds a college degree). On the other hand, the secular group is disproportionately male (49 percent to 32 percent), unmarried (58 percent to 40 percent), and young (42 to 49 years old, on average).

In addition, the sccbs data show that religion and secularism break down on ideological lines: Religious people are 38 percentage points more likely to say they are conservative than to say they are liberal (57 percent to 19 percent). In contrast, secular people are 13 points more likely to say they are liberal than to say they are conservative (42 percent to 29 percent).
