Crime Data from 2020 to 2024

******Notice: Transition to NIBRS-Compliant Crime Data Reporting The Los Angeles Police Department (LAPD) has completed its transition from the legacy Records Management System, which reported crime and arrest data under Uniform Crime Reporting (UCR) standards, to a modernized system fully aligned with the National Incident-Based Reporting System (NIBRS). As part of this transition, the legacy system is no longer active, and no new information will be entered. Consequently, the Crime Data from 2020 to Present dataset will no longer be updated. It will remain available on the portal for historical reference only. To provide the public with current and comprehensive information, LAPD now publishes datasets sourced directly from the new Records Management System in accordance with NIBRS standards. These datasets were introduced in October 2024 and are refreshed on a bi-weekly schedule: • [LAPD NIBRS Offenses Dataset | Los Angeles Open Data Portal] • [LAPD NIBRS Victims Dataset | Los Angeles Open Data Portal] The adoption of NIBRS ensures LAPD crime and arrest data meet national standards, enhancing transparency, accuracy, and accessibility for the public. ****** On March 7th, 2024, the Los Angeles Police Department (LAPD) adopted a new Records Management System for reporting crimes and arrests. This new system is implemented to comply with the FBI's mandate to collect NIBRS-only data (NIBRS — FBI - https://www.fbi.gov/how-we-can-help-you/more-fbi-services-and-information/ucr/nibrs). This dataset reflects incidents of crime in the City of Los Angeles dating back to 2020. This data is transcribed from original crime reports that are typed on paper and therefore there may be some inaccuracies within the data. Some location fields with missing data are noted as (0°, 0°). Address fields are only provided to the nearest hundred block in order to maintain privacy. This data is as accurate as the data in the database. Please note questions or concerns in the comments.

******注意：向符合NIBRS标准的犯罪数据报告体系转型
洛杉矶警察局（Los Angeles Police Department, LAPD）已完成从旧版记录管理系统（Records Management System, RMS）向完全适配国家基于事件的报告系统（National Incident-Based Reporting System, NIBRS）的现代化系统的转型，旧版系统曾依照统一犯罪报告（Uniform Crime Reporting, UCR）标准上报犯罪与逮捕数据。此次转型后，旧版系统已停止运行，不再有新信息录入。因此，2020年至今的犯罪数据集将不再更新，仅会保留在门户中供历史参考使用。
为向公众提供实时且全面的信息，LAPD现已发布基于新版记录管理系统生成、符合NIBRS标准的数据集。该类数据集于2024年10月推出，更新频率为每两周一次：
• [LAPD NIBRS犯罪数据集（LAPD NIBRS Offenses Dataset） | 洛杉矶开放数据门户]
• [LAPD NIBRS受害者数据集（LAPD NIBRS Victims Dataset） | 洛杉矶开放数据门户]
采用NIBRS标准可确保LAPD的犯罪与逮捕数据符合国家规范，提升数据的透明度、准确性与公众可及性。

2024年3月7日，洛杉矶警察局（LAPD）启用全新的犯罪与逮捕上报记录管理系统。该新系统旨在落实联邦调查局（Federal Bureau of Investigation, FBI）仅收集NIBRS数据的强制要求（NIBRS — FBI - https://www.fbi.gov/how-we-can-help-you/more-fbi-services-and-information/ucr/nibrs）。
本数据集可追溯至2020年的洛杉矶市犯罪事件。该数据由纸质原始犯罪报告转录而来，因此数据中或存在一定偏差。部分位置字段因数据缺失标注为（0°, 0°）。为保护隐私，地址字段仅精确至最近的百米街区。本数据的准确性与数据库内留存数据一致。如有任何疑问或意见，欢迎在评论区留言反馈。
