Interpreting the Violent Crime Maps

When interpreting the Marble Rock violent crime map, keep in mind that violent crime rates are measured per resident. Areas with high visitor traffic, such as shopping districts, may appear to have higher crime rates simply because more crimes occur where people gather - even if few residents live there. For example, the city has few retail establishments, which can artificially inflate violent crime rates in that area. Red areas on the map do not necessarily mean a neighborhood is unsafe for residents.

More issues arise with places like airports, parks, and schools. Major airports always look like high-crime locations due to the large number of people and the low population nearby. Parks and designated recreational areas have the same problem. Of Marble Rock’s 537 residents, few live near recreational areas. Because many people visit, crime rates may appear higher even for safe parks. Crime occurs where people gather, whether they live there or not. Before assuming an area is unsafe, consider both per-capita crime rates and total crime counts, as well as the types of destinations nearby.
