The Roman and Eastern Catholic Churches in North America and Central America comprise 14 episcopal conferences, which together include 100 ecclesiastical provinces, each of which is headed by a metropolitan archbishop.
The provinces are in turn subdivided into 85 archdioceses, 400 non-archdiocesan dioceses and 15 territorial prelatures, each of which is headed by a bishop or an archbishop (metropolitan if he has one or more suffragans).
Some episcopal conferences include Military ordinariate (quasi dioceses), personal ordinariates and Eastern Catholic eparchies and/or exarchates that may not be part of an ecclesiastical province.
The other Eastern Catholic Churches with eparchies (dioceses) or exarchates established in the United States are not grouped into metropoliae.
All are immediately subject to the Holy See, with limited oversight by the head of their respective sui iuris church.
