Crime Incidents in 2023

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.

本数据集收录了华盛顿哥伦比亚特区大都会警察局（District of Columbia Metropolitan Police Department，MPD）在ASAP（Analytical Services Application）犯罪报告数据库中上报的事件的部分位置与属性子集。如需获取更多信息，请访问crimecards.dc.gov。本数据通过自动化流程共享，其中地址将被地理编码至哥伦比亚特区主地址仓库（Master Address Repository，MAR），并分配至对应的街道街区。部分犯罪点位的街区位置无法自动分配，导致其x、y坐标为0,0，此类点位可通过MAR地理编码器（MAR Geocoder）进行交互式分配。2020年2月1日，犯罪数据的地理分配方法进行了修改以提升准确性。自2020年1月1日起，所有犯罪数据将在进行街区级匿名化处理之前，先行计算选区（Ward）、社区咨询委员会（Advisory Neighborhood Commission，ANC）、单人选区（Single Member District，SMD）、商业促进区（Business Improvement District，BID）、社区集群、投票选区、街区组及普查区（Census Tract）等字段值，而非在完成街区级匿名化处理后再进行计算。此项变更约影响1%的选区分配结果。
