This data is available for Arlington:
Violent crimes, non-violent crimes, floods, hurricanes, earthquakes, wildfires, tornadoes.
As for the crime map in Arlington – it reminded me that Arlington is a city – so there is definitely some crime here – especially by the densely populated areas. Clarendon looks like a crime central, but if you ask most of the residents if they feel unsafe – they would tell you “no”. It’s interesting to see the maps and know the perceptions of the community.
So what data is Trulia using? Trulia uses Google Maps as a base, then pulls in data from – depending on the hazard in question – the US Geological Survey, the National Weather Service, FEMA and the NAtional Flood Insurance Program, the NAtional Oceanic & Atmospheric Administration, the USDA Fire Service, Spotcrime.com and Crimereport.com, and more. It rates an area’s safety simply by how often and how recently a particular disaster has struck a region.
