Dearborn, Michigan has the highest concentration of Arab Americans in the United States, at over 40%. The rest of Metro Detroit has an even larger population of Lebanese residents. Brooklyn, New York has one of the oldest Lebanese populations in America, dating over 125 years; one large center is in the Bay Ridge section. Once predominantly Christian, the Lebanese in Bay Ridge are today equally split between Muslims and Christians. South Paterson, New Jersey historically had a large Lebanese Christian population dating back to the 1890s, but only a few remain, and the neighborhood has largely been replaced by new Palestinian immigrants. Brooklyn holds a significant Lebanese community, with a Maronite Cathedral the center of one of two eparchies for Maronite Lebanese in the United States, the other being in Los Angeles.
