Crime Incidents in 2022

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，犯罪数据地理区域分配方法完成修订，以提升数据准确性。自2020年1月1日起，所有犯罪数据在开展街区级匿名化处理前，将预先完成选区（Ward）、邻区咨询委员会（ANC）、单名选区（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）等地理标识字段的数值计算，而非在匿名化流程完成后再进行相关计算。此次修订约影响1%的选区分配结果，且该变更未应用于2020年之前的数据集。
