A faith-base community is a community with members who all believe in the same religious concepts, or at least they did when it was founded. Many faith-based communities are communes, although this is not a requirement. An example of faith-based communities is Amish country in the US. Also, in 1846-1847, many Mormons migrated westward to establish a faith-based community in Utah. Some people include Israel and Iran as faith-based communities, given the importance Judaism and Shia Islam respectively, in those countries.
