RMS Crime Incidents 2021

<div>This dataset is for RMS Crime Incidents for 2021. For the comprehensive dataset which includes all records please refer to the&nbsp;<a target='_blank' href='https://data.detroitmi.gov/datasets/detroitmi::rms-crime-incidents/about' rel='nofollow ugc noopener noreferrer'>RMS Crime Incidents</a>&nbsp;dataset.&nbsp;</div><div>&nbsp;</div><p>The RMS Crime Incidents dataset consists of crime reports from the Detroit Police Department Records Management System (RMS). This data reflects criminal offenses reported in the City of Detroit that DPD was involved in the 2021 calendar year. Incident data is typically entered into mobile devices by the officer in the field when responding to an incident. Incidents that occurred in Detroit but in a location that is under the jurisdiction of the Michigan State Police (MSP) or Wayne State University Police Department (WSUPD), such as on an expressway, Belle Isle, or around Wayne State University, are included only if the incident is handled by DPD. Such records are reviewed in a monthly audit to ensure that the incidents are counted by one and only one agency (MSP or DPD). This data is updated daily.<span>&nbsp;</span></p><p>For each crime incident, one or more offense charges are recorded, and each row in the dataset corresponds with one of these charges. An example could be a domestic assault where property was also vandalized. Offense charges that occurred at the same crime incident share a common incident number. For each offense charge record (rows) details include when and where the incident occurred, the nature of the offense, DPD precinct or detail, and the case investigation status. Locations of incidents associated with each call are reported based on the nearest intersection to protect the privacy of individuals.</p><p>RMS Crime Incident data complies with Michigan Incident Crime Reporting (MICR) standards. More information about MICR standards is available via the <a target='_blank' href='https://www.michigan.gov/msp/divisions/cjic/micr' rel='nofollow ugc noopener noreferrer'>MICR Website</a>. The Manual and Arrest Charge Code Card may be especially helpful. There may be small differences between RMS Crime Incident data shared here and data shared through MICR given data presented here is updated here more frequently which results in a difference in a cadence of status updates. Additionally, this dataset includes crime incidents that following an investigation are coded with a case status of ‘Unfounded’. In most cases, this means that the incident occurred outside the jurisdiction of DPD or otherwise was reported in error. The State of Michigan, through the MICR program, reports data to the National Incident-Based Reporting System (<a target='_blank' href='https://www.fbi.gov/how-we-can-help-you/more-fbi-services-and-information/ucr/nibrs' rel='nofollow ugc noopener noreferrer'>NIBRS</a>).</p><p><a target='_blank' href='https://data.detroitmi.gov/search?q=RMS&amp;sort=Title%7Ctitle%7Cdesc' rel='nofollow ugc noopener noreferrer'>Yearly Datasets</a> for RMS Crime Incidents have been added to the ODP. This is to improve the user's experience in handling the large file size of the records in the comprehensive dataset. You may download each year separately, which significantly reduces the size and records for each file. In addition to the past years, we have also included a year-to-date dataset. This captures all RMS Crime Incidents from January 1, 2025, to present.</p><p>Should you have questions about this dataset, you may contact the Commanding Officer of the Detroit Police Department's Crime Data Analytics at 313-596-2250 or <a>[e-mail]</a>.</p>

<div>本数据集为2021年RMS犯罪事件数据集。如需获取包含全部记录的完整数据集，请参阅<a target='_blank' href='https://data.detroitmi.gov/datasets/detroitmi::rms-crime-incidents/about' rel='nofollow ugc noopener noreferrer'>RMS犯罪事件</a>数据集。</div><div>&nbsp;</div><p>RMS犯罪事件数据集源自底特律警察局记录管理系统（Detroit Police Department Records Management System，缩写RMS）的犯罪报告。该数据涵盖2021日历年期间底特律市内由底特律警察局（DPD）处置的报案刑事案件。事件数据通常由外勤警员在出警时通过移动设备录入。对于发生在底特律境内但隶属于密歇根州警察局（Michigan State Police，缩写MSP）或韦恩州立大学警察局（Wayne State University Police Department，缩写WSUPD）管辖区域的事件——例如高速公路、贝勒岛（Belle Isle）或韦恩州立大学周边区域——仅当该事件由DPD处置时才会被纳入本数据集。此类记录会通过月度审计进行核查，以确保每个事件仅被唯一的机构（MSP或DPD）统计。本数据集每日更新。<span>&nbsp;</span></p><p>针对每一起刑事案件，系统会记录一项或多项犯罪指控，数据集中的每一行均对应其中一项指控。例如一起同时伴随财物损毁的家庭殴打案件。同一刑事案件下的多项犯罪指控将共享同一个事件编号。每条犯罪指控记录（即数据行）包含的详细信息包括：事件发生的时间与地点、犯罪性质、DPD辖区或负责部门，以及案件调查状态。为保护当事人隐私，与每一通报警相关的事件位置将以最近的路口坐标进行上报。</p><p>RMS犯罪事件数据符合密歇根州犯罪事件报告（Michigan Incident Crime Reporting，缩写MICR）标准。有关MICR标准的更多信息可通过<a target='_blank' href='https://www.michigan.gov/msp/divisions/cjic/micr' rel='nofollow ugc noopener noreferrer'>MICR官方网站</a>查询，其中《操作手册与逮捕指控编码卡》尤为实用。由于本数据集的更新频率更高，导致状态更新节奏存在差异，因此本平台发布的RMS犯罪事件数据与通过MICR渠道发布的数据可能存在细微差别。此外，本数据集包含经调查后被标记为“无依据（Unfounded）”的刑事案件。在大多数情况下，这意味着该事件发生在DPD管辖范围之外，或以错误方式上报。密歇根州通过MICR项目将数据上报至全国基于事件的报告系统（National Incident-Based Reporting System，缩写NIBRS）。</p><p><a target='_blank' href='https://data.detroitmi.gov/search?q=RMS&amp;sort=Title%7Ctitle%7Cdesc' rel='nofollow ugc noopener noreferrer'>RMS犯罪事件年度数据集</a>已添加至ODP平台。此举旨在优化用户处理完整数据集庞大文件体量的使用体验。用户可按年度单独下载，此举将显著降低单个文件的大小与记录条数。除过往年度数据集外，本平台还纳入了本年度迄今数据集，涵盖2025年1月1日至今的全部RMS犯罪事件记录。</p><p>如您对本数据集有任何疑问，可拨打313-596-2250联系底特律警察局犯罪数据分析部门主管，或发送邮件至<a>[e-mail]</a>。</p>
