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 north 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 draw large crowds with few residents nearby, so they read as high-crime spots. Parks and recreational areas, of which Key Biscayne has 4, do the same, and of Key Biscayne's 16,775 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.
