Global Ecclesiastical Jurisdictional Boundaries: Authoritative Data, Provenance, and Documentation
The Global Ecclesiastical Jurisdiction Data Repository is a geographic data and documentation resource for representing the territorial organization of the Catholic Church. It provides structured, geospatially referenced boundaries for ecclesiastical jurisdictions and associated administrative information, together with the provenance, sources, attribution requirements, and documentation needed to understand and responsibly use the data.
Ecclesiastical jurisdiction is used in this repository as a geographic and administrative term for the territorial and other geographically defined structures through which the Catholic Church’s temporal operations are organized and governed. At the universal level, the Church is governed by the Roman Pontiff and the College of Bishops, with the Pope as its head (CIC, can. 330 - 336). Below this level, the Church is organized geographically through particular Churches and their groupings, including dioceses, ecclesiastical provinces, and episcopal conferences.
In this repository, Administrative 0 represents episcopal conferences, Administrative 1 represents ecclesiastical provinces, and Administrative 2 represents dioceses and equivalent jurisdictions. These administrative levels describe the geographic organization represented in the repository and do not constitute a complete hierarchy of canonical authority. In canon law, the exercise of governance is described as potestas regiminis, also called the power of jurisdiction (potestas iurisdictionis) (CIC, can. 129 §1). The Code of Canon Law identifies dioceses as particular Churches and recognizes related territorial forms, including territorial prelatures, territorial abbeys, apostolic vicariates, apostolic prefectures, and certain apostolic administrations as assimilated to dioceses (CIC, can. 368). Official Vatican documentation also uses the broader term ecclesiastical circumscriptions for these and other geographically defined ecclesiastical entities.
The boundaries represented in this repository are ecclesiastical boundaries, not political boundaries. An ecclesiastical jurisdiction may cross international or subnational political borders, and its geographic extent should not be assumed to correspond to the territory of a country, state, province, or other civil government. The repository provides a geographic representation of these jurisdictions for research, cartography, and analysis; the status and territorial competence of these jurisdictions remain matters of ecclesiastical law and competent ecclesiastical authority.

The repository currently represents primarily Latin Rite Church jurisdictions (of which the Roman Rite is a subset), with a few Eastern Catholic Church jurisdictions incorporated at the diocesan and episcopal-conference scales that are bi-rite. The episcopal conference layer likewise reflects a predominantly Latin Church geographic structure and does not yet provide comprehensive coverage of all Eastern Catholic Churches and their distinct ecclesiastical organizations. Additional geographic layers representing the Eastern Catholic Churches and other ecclesial traditions are currently under development and are expected to become available in 2027, expanding the repository toward more comprehensive coverage of the Catholic Church’s diverse geographic and ecclesiastical structures.
Upper level of Catholic governance, representing episcopal conferences: assemblies of bishops responsible for shared pastoral matters within defined territories (CIC, can. 447).
The second geographic level represented in this repository, consisting of ecclesiastical provinces: groupings of neighboring particular Churches under a metropolitan see (CIC, can. 431 - 432)
The third geographic level represented in this repository, consisting of dioceses and equivalent jurisdictions, including territorial prelatures, apostolic vicariates, prefectures, territorial abbeys and other apostolic administrations (CIC, can. 368).
