Ontario, CA, United States

This city in the Inland Empire is a sprawling suburban hub with a diverse but largely working-class population of 175,265. While the warm climate and major airport attract businesses, Ontario's bureaucratic headaches and lack of amenities make it best suited for pragmatic transplants looking for affordable living outside Los Angeles.

The economy here is dominated by warehousing and service jobs, though manufacturing still plays a role. Ontario's roots as an agricultural colony are visible in the dairy farms and olive production that continue today. However, much of the southern part of the city is slated for residential and commercial redevelopment, known as the "New Model Colony." This rapid growth has strained the city's infrastructure, with persistent bureaucratic challenges around things like permitting.

On the plus side, Ontario boasts a diverse population, with sizable Hispanic, Asian, and Black communities. The city has a young median age of 34 and affordable housing, making it appealing for families and cost-conscious individuals. But the suburban sprawl, lack of entertainment options, and occasional Santa Ana winds can be a turnoff for those seeking an urban, amenity-rich lifestyle.
