There are approximately 80 Jesuit provinces around the world (although their number and boundaries have never been static). Each province has a superior who is simply called "the Provincial," and who, in turn, reports directly to the central Jesuit government or "curia" in Rome. Each Jesuit provincial will attend GC 36, as well as a proportionate number of Jesuits from each province who are elected by their peers in a secret ballot. More than 200 Jesuits are expected to attend GC 36, and 33 of those men will be Americans and Canadians.
