Last week, the District, Measured blog reported an uptick in gun violence in D.C. this summer and charted which neighborhoods have seen the biggest surge in crimes involving a gun over the last year (Petworth, Brightwood, Stanton Park, Capitol Hill and NoMa).

The Urban Institute released a new report as part of a larger study on D.C. highlighting which neighborhoods in the city have seen the biggest change in the number of violent crimes between 2000 and 2014. Violent crime — aggravated assaults, robberies and homicides — has dramatically dropped, though there are pockets of the city where such crime has persisted, particularly in neighborhoods in Northeast and Southeast.

The distinction of having the largest drop in crime goes to the fast-changing Southeast-Navy Yard neighborhood, where violent crime fell from 59 crimes for every 1,000 residents to six.  The Chinatown, Mount Vernon and downtown areas also saw a dramatic decrease during that time, experiencing 33 fewer crimes per 1,000 residents.

Crime during this time decreased citywide, but four neighborhoods in Ward 7 — Eastland Gardens-Kenilworth, Deanwood-Lincoln Heights, Mayfair-Hillbrook and River Terrace-Benning — saw increases in crime. The Lamont Riggs and Fort Totten area also saw a slight uptick in violent crimes during this period, with one additional violent crime per 1,000 residents.

The Urban Institute attributes Navy Yard’s crime drop to the major development in the neighborhood. In the 90s, the neighborhood was a troubled industrial area. But starting around 2000, there was a concerted effort to redevelop the area and new businesses and Nationals Park came, transforming Navy Yard into the commercial and residential area it is today. Between 2000 and 2012, the average family income there increased 274 percent and the population grew from 1,825 residents to 2,800 in 2012.

The Urban Institute also broke down the data by the types of crime. The first map tracks the number of robberies by neighborhood, the second one looks at the number of aggravated assaults and the third maps homicides between 2000 and 2014. According to the Urban Institute report, the notable decrease in homicides from the 90s stems from a number of possible factors, including economic growth, better policing and demographic changes. Improved medical care and EMT responses could also play a factors, preventing victims of gun violence from dying.

But there has been a recent uptick in homicides, and the Urban Institute writes this “suggests that a broader array of strategies may be needed to further reduce homicides. For example, a growing number of homicides are related to domestic violence: 17 in 2014 compared with nine in 2012.
