Crime Incidents in 2021

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，犯罪数据地理区划分配方法得到修订，以提升计算准确性。自2020年1月1日起，所有犯罪数据将在区块级匿名化处理之前（而非之后）完成选区（Ward）、顾问社区委员会单成员区（ANC）、单一成员分区（SMD）、商业改善区（BID）、社区集群（Neighborhood Cluster）、投票区（Voting Precinct）、街区组（Block Group）及普查区（Census Tract）的数值计算。此次修订将影响约1%的选区分配结果，且未适用于2020年之前的数据集。
