Crime Incidents in 2016

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特区大都会警察局（Metropolitan Police Department，MPD）上报至分析服务应用程序（Analytical Services Application，ASAP）犯罪报告数据库的事件的位置与属性子集。欲获取更多信息，请访问crimecards.dc.gov。
本数据集通过自动化流程生成：流程中会将地址地理编码至特区主地址库（Master Address Repository，MAR），并匹配至对应的街道街区。部分犯罪点位的街区无法自动匹配，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）进行交互式匹配。
2020年2月1日，为提升数据准确性，犯罪数据的地理分配方法进行了优化调整。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（而非之后），计算其Ward、ANC、SMD、BID、Neighborhood Cluster、Voting Precinct、Block Group及Census Tract字段值。此次变更约影响1%的Ward分配结果。
