Crime Rates Around Methadone Treatment Facilities, Hospitals, Convenience Stores, and Residential Neighborhoods in Baltimore, 1999–2001


Crime Rates Around Methadone Treatment Facilities, Hospitals, Convenience Stores, and Residential Neighborhoods in Baltimore, 1999–2001 Reports of crime did not change significantly with distance from methadone clinics. In contrast, crime reports increased with proximity to convenience stores and decreased with proximity to points within residential neighborhoods. Crimes measured for this study were all FBI Part I crimes, including homicide, forcible rape, robbery, aggravated assault, burglary, larceny theft, motor vehicle theft, and arson. The distance from sites was measured as concentric circles around each site. Study sites included 13* methadone treatment centers, 10 hospitals, 13 convenience stores, and 13 residential points at the center of a block on a secondary street.
*One site includes three clinics analyzed together as one site.

Crimes measured for this study were all FBI Part I crimes, including homicide, forcible rape, robbery, aggravated assault, burglary, larceny theft, motor vehicle theft, and arson.

The figure shows that during both day (7 am to 7 pm) and night (7 pm to 7 am), the rate of crime at distances of 25, 50, 75 and 100 meters from methadone clinics is similar at each of the distances, generating a roughly horizontal line. The rates range from 1.2 to 1.8 during the day, and from 0.7 to 1.3 at night.

The plot for convenience stores shows the highest crime rates at 25 meters with rates of 2.9 during the day, and 3.4 at night, with declines to a level plateau of 0.7 to 1 at distances of 50, 75 and 100 meters.

Crime rates for hospitals and residential areas linearly increased with distance during the day, from 0.7 to 1.0 at 25 meters up to about twice that rate at 100 meters. At night, rates for residential areas also increased with distance, from 0.7 to 2.0, while at night crime rates were similar at all distances from hospitals, in the range of 0.4 to 1.2.
