DAAR includes data from the US Census and the religion censuses from 1890 to 2010. However, based on changes in data collection methodologies over time and changes in denominations, there are several gaps in the data. The Data Availability Matrix provides a listing of the data included in DAAR for you to easily see where there are data gaps and availability.
