Last year marked 500 years since the Protestant Reformation, but it’s not hard to see that the impact of the most significant Church split in history is still felt today. For instance, the World Christian Encyclopedia estimates that over 30,000 Christian denominations exist worldwide. Churches of all stripes practice their own flavor of ministry in cities across the United States, all based on particular interpretations of scripture and style. But what is the denominational makeup of each city in America? What are the most Catholic cities? Which areas have the greatest percentages of Baptist, or Lutheran or Pentecostal residents?
Over the years, Barna has been tracking denominational affiliation and publishing this data in our cities reports. In the infographic below, we list the top five cities for each of the main denominational categories and a few of the largest Protestant ones (specific denominational definitions below).
