Crime Incidents in 2009

The dataset contains a subset of locations and attributes of incidents reported in the ASAP (Analytical Services Application) crime report database by the District of Columbia Metropolitan Police Department (MPD). Visit crimecards.dc.gov for more information. This data is shared via an automated process where addresses are geocoded to the District's Master Address Repository and assigned to the appropriate street block. Block locations for some crime points could not be automatically assigned resulting in 0,0 for x,y coordinates. These can be interactively assigned using the MAR Geocoder. On February 1 2020, the methodology of geography assignments of crime data was modified to increase accuracy. From January 1 2020 going forward, all crime data will have Ward, ANC, SMD, BID, Neighborhood Cluster, Voting Precinct, Block Group and Census Tract values calculated prior to, rather than after, anonymization to the block level. This change impacts approximately one percent of Ward assignments.本数据集包含华盛顿哥伦比亚特区大都会警察局（Metropolitan Police Department，MPD）在ASAP（Analytical Services Application）犯罪报告数据库中上报的部分事件地点与属性信息。欲获取更多详情，请访问crimecards.dc.gov。本数据集通过自动化流程共享：地址将被地理编码至特区主地址库（Master Address Repository，MAR）并分配至对应的街道街区。部分犯罪事件点的街区位置无法自动分配，导致其x、y坐标为0,0。此类坐标可通过MAR地理编码器进行交互式分配。2020年2月1日，犯罪数据地理分配方法进行了优化以提升准确性。自2020年1月1日起，所有犯罪数据将先完成Ward、ANC、SMD、BID、社区集群、投票区、街区组及人口普查区的属性计算，再进行街区级匿名化处理，而非此前先匿名化再计算的流程。此次变更约影响1%的选区分配结果。
