All three are distinct categories from Presbyterian or Reformed (7%) in this report. The Reformed family of churches is one of the largest Christian denominations, representing 75 million believers worldwide.<ref name="adherents.com">{{cite web |url=http://www.adherents.com/adh_branches.html#Christianity |archive-url=https://web.archive.org/web/19990819112057/http://adherents.com/adh_branches.html#Christianity |url-status=usurped |archive-date=19 August 1999 |title=Major Branches of Religions}}</ref>
