If the unincorporated community of East Los Angeles were actually an incorporated city, with a 2024 estimated population of 114,544, 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 is estimated to have considerably slowed by 2024. At the other end of the spectrum was the City of Industry (not listed above). Although the city has a very small population, it saw a population decline, from the year 2000 through 2023, of more than 80%.
