There are about 175,000 Bahá’ís in the United States (less
than one percent of the nation’s population), residing in more than 9,000
localities. The makeup of the faith’s adherents is very diverse. The largest
communities are in California, Georgia, Illinois, South Carolina, and Texas.
There are Bahá’í communities in every state.
