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 southwest part of the county 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 Nassau County has 163, do the same, and of Nassau County's 1,456,700 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.
