About this data

Leader Insights collects statistics about U.S. churches from published research. Every number is checked against the wording of the original source before it is published, and each statistic links back to the study it came from. Different studies define the same topic differently, so figures from different sources are not directly comparable; each is labeled with its publisher and year.
