Religion of New Orleans:
New Orleans is notably absent from the Protestant Bible Belt that dominates religion in the Southern United States. In New Orleans and the surrounding Gulf Coast area, the predominant religion is Catholicism. Within the Archdiocese of New Orleans, 35.9% percent of the population is Roman Catholic. The influence of Catholicism is reflected in many of the city's French and Spanish cultural traditions, including its many parochial schools, street names, architecture, and festivals, including Mardi Gras.
New Orleans also famously has a presence of its distinctive variety of Louisiana Voodoo, due in part to syncretism with Roman Catholic beliefs, the fame of voodoo practitioner Marie Laveau, and New Orleans' distinctly Caribbean cultural influences. Although the exotic image of Voodoo within the city has been highly promoted by the tourism industry, there are only a small number of serious adherents to the religion.
New Orleans' pre-Katrina population of 10,000 Jews has now dropped to 7,000. In the wake of Katrina, all New Orleans synagogues lost members, but were able to re-open in their original locations, except for Congregation Beth Israel, the oldest and most prominent Orthodox synagogue in the New Orleans region. Beth Israel's building in Lakeview was destroyed by flooding, and it is currently in temporary quarters in Metairie.
