While updating and fixing the data set, I compiled some interesting notes about the Catholic Dioceses of the US:

• Ecclesiastical Province with the largest number of dioceses: Saint Paul and Minneapolis (10 dioceses)
• Ecclesiastical Province with the smallest number of dioceses: Tied between the Archdiocese of Washington (DC) and the Archdiocese of Anchorage–Juneau.
• Largest diocese by area: Fairbanks (area of 401,823 square miles)
• Smallest diocese by area: Brooklyn (area of 179 square miles)
