Guide to Understanding Crime and Data
The CommunityCrimeMap.com website was developed to help citizens visualize and understand crime in their communities. Since 2002, the Alexandria Police Department has provided searchable online crime data through the City's online crime search engine. Residents can query and view Alexandria crime data using an online Geographic Information System (GIS). Crime data is standardized so that citizens can view data across jurisdictional boundaries. It also allows citizens to view crime for an entire region, neighborhood or block.
The data represented is extracted daily from the Alexandria Police Department’s Records Management System (RMS). The data is broken out into several general categories. Explanations of each general crime category are listed below in the table. Crime data is dynamic and changes as report statuses and cases are reclassified. Changes and updates to case type and status may take from one to seven days before they are visible on CommunityCrimeMap.com.
CommunityCrimeMap.com details two types of crimes: Part 1 and Part 2 offenses. The difference between Part 1 and Part 2 crimes is important to understand as you review the following information:
Part 1 Crime
- Homicide
- Rape
- Robbery
- Aggravated Assault
- Burglary
- Larceny
- Stolen Auto
Part 2 Crime
- Drunkenness
- Disorderly Conduct
- Liquor Law Violations
- Drug Offenses
- Gambling
- Prostitution
- Driving Under the Influence
- Destruction of Property/Vandalism
The Alexandria Police Department reports the crimes listed above to the Virginia State Police each month. This data is calculated, analyzed and reported in both Crime in Virginia and the FBI’s Crime in the United States publications.
Many of the Part 2 crimes are generated by police officers who witness the offense in progress or through investigation. Higher numbers of certain Part 2 offenses often show an increase in police presence in a certain neighborhood. Officers are directed to target alcohol offenses, gambling, drugs and persons who are driving under the influence. Detectives also conduct prostitution stings that often lead to arrests and an increase in reported prostitution offenses.
