The quick read

Reading Ontario, CA beyond the headline numbers

Ontario sits inside San Bernardino County, California, at roughly 34.06°N, -117.65°W. Population 171,214, $88,941 median household income. Median home value $607,600, median rent $2,030. Poverty rate 12.4%, read against that income figure since two cities on the same median can differ underneath it.

Poverty in Ontario, CA stands at 12.4%, above the midpoint of reporting cities. A median income can look comfortable while a share this size sits well beneath it, which is why the two figures belong together.

The median home in Ontario costs around 6.8 times what a median household earns in a year -- the most expensive quarter of reporting cities, and far enough ahead of local pay that ownership is largely closed to median earners.

Remote work covers 9.1% of Ontario workers, under the midpoint for reporting cities.

Among the CDC measures on this page, lack of health insurance departs furthest from its peer median: 17% in Ontario, the highest-prevalence quarter of the 3,759 cities reporting that measure.

Ontario's median age is 33.5 years, in the youngest quarter of reporting cities.
