This website presents an interactive visualisation of global Catholic statistics. The data is sourced from Catholic-Hierarchy.org, a comprehensive website that collates information on each diocese at the national level.
Data Coverage: Our database spans from 1950 to the present and is available at two levels of temporal resolution:
Data Quality Statement: The dataset presented here has been derived from Catholic-Hierarchy.org (https://www.catholic-hierarchy.org/sources.html), a secondary aggregator of publicly available information. This approach of relying on aggregated online sources can result in moderate and variable data quality. The reliability of the data is contingent upon regional information accessibility. Consequently, data from nations with robust digital reporting is generally more complete, whereas regions with limited data access may exhibit significant omissions. This site's primary data source is Catholic-Hierarchy.org, a privately operated and continuously updated database maintained by David M. Cheney. The site provides current and historical information on Catholic dioceses, bishops, and religious institutes worldwide, including both the Latin-rite and Eastern Catholic Churches. Catholic-Hierarchy.org explicitly states that it is not officially endorsed or approved by any Catholic Church authority and that "the data included on this site come from a variety of sources." The Vatican's Annuario Pontificio, Acta Apostolicae Sedis, Acta Sanctae Sedis, and other ecclesiastical and scholarly publications are among the sources from which this information is drawn. In preparing the visualizations on this site, the data has been adapted and, where needed, statistically processed (for example, by interpolation of missing values) in order to enable smooth trend analysis and comparison. It should be noted that there may be some discrepancies between the raw original data and the figures displayed here. We would like to express our sincere gratitude to Catholic-Hierarchy.org and David M. Cheney for their sustained efforts in compiling and publishing the global Catholic structural data.
