Crime Incidents in 2025

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.

本数据集包含哥伦比亚特区大都会警察局（Metropolitan Police Department, MPD）在ASAP（Analytical Services Application，分析服务应用程序）犯罪报告数据库中上报的事件的位置与属性子集。更多信息可访问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仓库（Master Address Repository），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完成分配，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得到优化，以提升准确性。自2020年1月1日起，所有犯罪数据的Ward（选区）、ANC（Advisory Neighborhood Commission，社区顾问委员会）、SMD（Single Member District，单成员选区）、BID（Business Improvement District，商业改善区）、Neighborhood Cluster（社区集群）、Voting Precinct（投票选区）、Block Group（街区组）以及Census Tract（普查区）字段值，将在进行街区级匿名化处理之前而非之后完成计算。此次变更将影响约1%的选区分配结果。
