Figure 7.6:
Leading Christian denominations in the United States and Canada, shown by counties (for the United States) or census districts (for Canada). In the shaded areas, the indicated church or denomination claims 50 percent or more of the total church membership. The most striking features of the map are the Baptist dominance through the South, a Lutheran zone in the upper Midwest, Mormon dominance in the interior West, and the zone of mixing in the American heartland.
