I gave you the link to the map. It may kick you to the disclaimer first. All the disclaimer says, is don't use this if you are having an emergency. You don't have to sign up for anything.
The other type of crime is also be rare, but the circumstances of the crimes are more under the control of the homeowner. These are thefts and burglary. In every case I have been made aware of there was indications of either an insider knowing of a valuable in the home or the home or vehicle was not properly secured. The most recent thefts on our street came when a new homeowner left valuables unattended in plain view from the street (garage or bed of pickup).
In our local neighborhood two factors make it a less likely target for crime. (1) There are a good number of retirees at home during the day, (2) everyone tends to look out for one another as much is as possible.
Safety is an important consideration and often overlooked. Crime is one factor, but there are others. My blog 'Safety in the time of Fires', below, discusses a number of worthwhile safety topics and includes links to valuable information.
