The Interpreting the Crime Maps section below explains how to read the colors.

The Intangible Cost of Crime in Ontario, CA

The totals above count tangible costs only.

That intangible cost in Ontario totals $156,620,918 ($862 per resident), and all of it comes from violent crime rather than property loss. Added to the tangible costs, the full estimate reaches $247,842,190 ($1,364 per resident). All Cost of Crime figures come from scholarly research on the cost of crime.

Interpreting the Crime Maps

Crime rates on the map are measured per resident, so areas with heavy visitor traffic can read high because crime follows crowds, even where few people live. The northeast part of the city holds more retail establishments, which lifts recorded crime around those blocks. A red area does not always mean the neighborhood is unsafe for residents.

Airports, parks, and transit hubs create the same effect. Major airports, of which Ontario has 1, draw large crowds with few residents nearby, so they read as high-crime spots. Parks and recreational areas, of which Ontario has 9, do the same, and of Ontario's 181,728 residents few live beside them. Before assuming an area is unsafe, weigh both the per-capita rate and the total number of incidents, and note what sits nearby.
