If the unincorporated community of East Los Angeles were actually an incorporated city, with a 2024 estimated population of 111,647, it would rank as Los Angeles County's tenth most populous city.
Santa Clarita (listed above) had been L.A. County's fastest growing city through 2020. That population growth, however, had considerably slowed by 2024.
