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.
