Crime Incidents in 2025

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. This change was not applied to datasets pre-2020.

2020年2月1日，为提升犯罪数据地理区划赋值的准确性，相关方法进行了修订。自2020年1月1日起，所有犯罪数据的选区(Ward)、邻里咨询委员会(ANC, Advisory Neighborhood Commission)、单人选区(SMD, Single Member District)、商业改善区(BID, Business Improvement District)、邻里集群(Neighborhood Cluster)、投票区(Voting Precinct)、街区组(Block Group)及普查区(Census Tract)的属性值，将先于街区级匿名化处理完成计算，而非在匿名化之后进行。此次修订将影响约1%的选区赋值结果，且未应用于2020年之前的数据集。
