Crimes cover the Gaithersburg Census place (the boundary outlined on the map), over the last 12 months. Crime is compared per resident (rate), so a large, busy area can have a high total but a lower rate; crash counts are compared to the average Montgomery County neighborhood. Source: Montgomery County open data (Police, Permitting Services, Health and Human Services) and M-NCPPC. MCPD publishes each incident at its hundred block (the street centerline), and Census place outlines run along streets, so incidents within about 30 meters of the outline are counted here, which means an incident on a street shared by two places counts toward both. Montgomery County’s crime data is what the county’s police agencies report: the Montgomery County Police Department and the Rockville City, Gaithersburg City and Takoma Park police departments, whose reports the county feed carries. It leaves out the Chevy Chase Village Police Department’s town and the grounds of the federal and campus police (the National Institutes of Health, Naval Support Activity Bethesda, NIST, the Navy’s Carderock Division in West Bethesda, the FDA’s White Oak campus and Montgomery College’s Rockville campus) and county parks and other M-NCPPC parkland, which the M-NCPPC Park Police patrol and whose incidents are not in the county feed; agencies that patrol parts of the county on their own, such as the Maryland State Police and Metro Transit Police, may report separately, so incidents they handle may not be in it. Reports that are not crimes (police information, lost and recovered property, mental-health petitions, missing persons, sudden deaths, suicides, overdoses, runaways, fugitive warrants) are not counted. About 1 in 7 reports has no usable location (more than 1 in 4 for the Takoma Park Police Department, 1 in 15 for Rockville City Police and 1 in 20 for Gaithersburg City Police), and about 1 in 6 serious violent-crime reports, so located counts understate crime, violent crime included, most in Takoma Park. Rape and other sex offenses are shown at block level (about 100 meters) without a case number to protect victims. Montgomery County publishes each crash’s report type (property damage, injury or fatal) from the state’s crash-reporting system, not the number of people hurt: an injury crash is counted as at least one injury and a fatal crash as at least one death, so injury totals are minimums. Interstate highways make up about 1% of the crashes in the feed, so crashes the Maryland State Police handled on I-495 and I-270 may be missing. Open data updates on a delay, so the most recent records may be incomplete. For general information only — not legal, financial, or real-estate advice.
