Mormon Americans are people from the United States who have ancestral or religious roots in the Latter-day Saints movement. Approximately 6.5 million Americans are practicing Mormons, while at least one million others have roots in the Mormon community.
Anthropologists and demographers increasingly consider Mormons to be a distinct ethnic group in America due to them meeting the general criteria of "shared cultural heritage, ancestry, origin myth, history, homeland, language or dialect, symbolic systems such as religion, mythology and ritual, cuisine, dressing style, art, and physical appearance."
These are people who consider(ed) themselves active adherents of the Mormon faith.
These are people who come from Mormon background but no longer consider themselves to be practicing Mormons.
These are people who have a parent, grandparent, or great-grandparent who was Mormon and have strong "ethnic Mormon" background.
