Los Angeles County has the second most populous city in the United States (Los Angeles, 3.8 million residents). It also has the second and fourth least populated cities in California (City of Industry and Vernon). These cities, along with Bradbury, have smaller populations than even the county's smallest unincorporated communities (Green Valley and Lake Hughes, both with a bit more than 800 residents each, located in the Sierra Pelona Mountains).
