The Diocese of Erie is organized into three vicariates — Northern, Eastern and Western — which together encompass seven deaneries: Erie West, Erie East, Greenville, DuBois, Oil City, Bradford and St. Marys. The map above illustrates these regions, offering a visual representation of the geographic breadth of the diocese and the expansive square mileage it serves.



The number of parishes across the Diocese of Erie reflects ongoing pastoral planning and a commitment to long-term vitality and sustainability. Since the initial round of pastoral planning began in 2017, the number of parishes has gradually decreased—from 124 in 2000 to 76 today—reflecting a thoughtful response to demographic shifts, priest availability and changing patterns of participation.

At the same time, there has been an increase in both mission and secondary churches. Mergers, partnerships and shared ministry models are helping to better align leadership and resources while supporting both parish life and the care of these spaces. Nationally, dioceses are undertaking similar efforts, recognizing that collaboration is essential to sustaining vibrant parish communities. Here in NWPA, this moment reflects a unified Church, rooted in the Eucharist and committed to serving all 13 counties.



The number of Sunday Masses has been reduced from 402 in 2000 to 353 in 2008, 319 in 2015 and 209 in 2025 — a reduction of nearly 50% over time.

This reflects clergy availability and parish restructuring, with Mass schedules thoughtfully consolidated in response to changing participation and the reality of many empty seats. These adjustments also allow priests to celebrate the liturgy with greater focus and care, balancing their time and pastoral responsibilities across multiple communities. Parishes continue to be cared for and maintained as vibrant places of worship, with Masses, ministries and services offered consistently each week, ensuring the faithful have access to the Eucharist across the diocese.
