According to a 2000 report on religion, which asked congregations to respond, Catholics are the largest religious group on Long Island, with non-affiliated in second place. Catholics make up 52% of the population of Nassau and Suffolk, versus 22% for the country as a whole, with Jews at 16% and 7%, respectively, versus 1.7% nationwide. Only a small percentage of Protestants responded, 7% and 8% respectively, for Nassau and Suffolk counties. This is in contrast with 23% for the entire country on the same survey, and 50% on self-identification surveys.
