According to California.com, "The Los Angeles Native American tribes consisted of three distinct groups which predate the California Missions’ establishment—Ventureno, Gabrielio, and Fernandeno. Though they aren’t federally recognized, the state of California acknowledges them... The second-largest urban region in the United State—the Greater Los Angeles Area—is home to 14 federally recognized California tribes. Two of these tribes are found in San Bernardino County, and 12 in Riverside. Orange, Ventura, and Los Angeles counties have many members of California tribes that aren’t federally recognized."
