Religious Affiliation By State
The United States is an overwhelmingly Christian nation. According to Gallup's yearly estimate on national religious preferences, more than 8 in 10 Americans say they are affiliated with a Christian religion. Some individual states exceed that level, and no state falls below 76% in attachment to Christianity. Only 8 of the 48 continental states have less than 80% of their residents identifying as Christian — Massachusetts (79%), Washington (79%), New York (79%), Nevada (79%), Idaho (79%), Colorado (78%), California (76%), and Oregon (76%).
About 2% of the U.S. population is Jewish. Several northeastern states — including New York, New Jersey, Connecticut, and Massachusetts, have Jewish populations above the national average. Though based on a small sample size, the data suggest that the District of Columbia has a higher proportion of Jewish residents than any U.S. state (about 10%).
