Washtenaw County Sheriff's Office Dashboard Help Tabs
The Sheriff's Office data and information dashboard provides data related to crime addressed by the Sheriff's Office. An expression of our commitment to openness and community engagement, its intent is to empower those interested to explore and better understand crime, public safety, and wellness in the communities we serve.
The dashboard consists of five (5) pages: Crime Overview, Victim Demographics, Arrest Demographics, Traffic Overview, and Subject Control. Each page features a map, several metrics, and various ways to filter the data. It contains data for the three (3) prior years plus the current year. Crime data is updated weekly. Subject Control data is updated bi-weekly and the data only goes back to October 2022. Each page is interactive, meaning you can click on a component in a visualization, and it will filter other components on the page.
Below is a guide to dashboard components and interactions.
Dashboard Pages (5)
The Crime Overview page is the primary page and contains data for all verified crimes.
The Victim Demographics page presents data that gives insight about the victims of crimes against person by race, ethnicity, gender, age, and incident type.
The Arrest Demographics page displays data about arrestees including race, gender, age, and incident type. The data is extracted by the date the incident occurred, not the date of arrest.
The Traffic Crashes, Stops & Violations page contains a traffic overview for the Sheriff’s Office including the reason and outcome of the traffic stop, demographics of citizens involved, violation type, and number of crashes.
The Subject Control page presents data related to when deputies physically control a subject (Subject Control) or successfully de-escalate a situation with a show of force.
Upon opening, the dashboard will present the current year’s data. You can view previous year’s data using the "Select Year" drop down in the upper right corner of the dashboard.
The data on each page of the dashboard is interactive. You can click on any item and the rest of the dashboard will filter to show the data related to the item you selected. Click the data source again to un-filter the dashboard.
A “tool tip” is a window that appears when hovering over a visualization. Most visualizations have a tool tip that provides additional details about the data.
A data location map is present on every page. Each map is organized by zip code to protect victim information. You can view data for different areas by selecting a zip code on the map or selecting an area from the bubble chart below the map. Multiple areas can be selected by clicking and dragging on the map or holding down the Ctrl key and selecting multiple areas on the bubble chart. To remove the filters, click on an empty area on the map. To remove the filters on the bubble map, click the selected bubble again.
Every offense is classified into a crime category. For example, any type of Aggravated Assault is in the Assault Offenses category. Each category can be expanded and filtered down further. Click on the category name to expand it. Then select the category name to filter for the entire category or select a specific offense within the category to filter by. To remove the filter, click on the category name again.
Selecting Multiple Objects
There are a few ways to select multiple data points on each page of the dashboard.
1. Click and drag your cursor across the objects you are trying to select
2. Hold down the control key on your keyboard and click on the objects you want to select
3. When available, use the filter drop downs
The available filters expand with the data. To expand the filter, you must first expand the data. To do this, expand the first category you want to look at and then hold down the control key on your keyboard and expand the other categories you want to view in the filter
To clear all selected filters, use the reset button in the bottom right corner
The source of the dashboard’s data are the reports created by investigating Deputy Sheriffs. As a part of a comprehensive case management process, reports are:
1. reviewed for general quality assurance and accuracy by supervisors (command) prior to final approval, and then
2. sent to a warrant detective for further review prior to being forwarded to the prosecutor’s office for their review and a charging decision.
Further, prior to uploading the data to the dashboard the raw information is reviewed by a command officer. Most discrepancies in the data are resolved during this comprehensive case management and review process. However, as the data is manually entered , human error is possible.
Data that is provided directly from the involved person to the investigating officer, including but not limited to race, gender, and age, is subject to inaccuracy and incompleteness. For example, Sheriff's Office personnel are not required to obtain a persons ethnicity nor is a person required to provide it if asked resulting in an increase in unknown values.
To ensure that you are viewing the most accurate data for your needs while navigating through and utilizing the dashboard, please be mindful of the filters you have selected and verify that only the filters you want are active.
For any additional questions you may have about the Dashboard, please visit our FAQ page.
We hope that you find the dashboard an empowering and useful tool to help understand the criminal and enforcement activity that your Sheriff’s Office responds to and engages in each and every day. You may direct feedback or questions regarding the dashboard to: [email protected].

- What is the purpose of the data & information dashboard?
The Sheriff's Office data & information dashboard provides data related to crime addressed by the Sheriff's Office. An expression of our commitment to openness and community engagement, its intent is to empower those who are interested to explore and better understand crime, public safety, and wellness in the communities we serve.
- How do I navigate the dashboard?
Please see our Data and Information Dashboard Guide tab.
- How often is the dashboard's data updated?
Crime data is updated weekly. Subject Control and Show of Force data is updated bi-weekly.
- Why is the historical data presented in the dashboard subject to change over time?
Change in data can occur because of delayed crime reporting (crime counts are based on the date the crime occurred, not the date the crime is reported), updates to the crime report (details of the report may be edited as crimes are investigated), and changes to the National Incident-Based Reporting System (NIBRS) crime codes as determined by the State of Michigan or the FBI. (See definitions tab for an explanation of NIBRS.)
- I live in Washtenaw County, why don't I see my area under the "Area" Section?
The Sheriff's Office provides comprehensive law enforcement and investigative services along with an array of specialty and supporting services on a contractual basis to political jurisdictions that so request it. When this occurs we become, in effect, the jurisdiction's "police agency". If an incident occurs in an area not served by the Sheriff's Office via contract, that incident will fall under "NON" on the dashboard designating it as "non-contract".
- Why can't I see incidents that happened on my specific street?
Incident maps are organized by zip code to protect victims of certain crimes including, by way of example but not limitation, domestic violence or sexual assault.
- Can I download the data on the dashboard?
You cannot download the raw data, but you can download the dashboard as a PDF or PowerPoint by clicking the "download" button at the bottom of the dashboard. The dashboard is available 24/7 on the Sheriff's Office website.
- Who should I contact regarding Washtenaw County Sheriff's Office data?
You may direct constructive feedback or questions regarding the dashboard to: [email protected]
- Why are there so many unknown ethnicities?
Ethnicity is not information officers are required to obtain. As a result, it can only be filtered if provided during an investigation. If not provided, it is categorized as "unknown".
- How do we know this data is accurate?
The source of the dashboard's data are the reports created by investigating Deputy Sheriffs. As a part of a comprehensive case management process, reports are:
- Reviewed for general quality assurance and accuracy by supervisors (command) prior to final approval, and then
- Sent to a warrant detective for further review prior to being forwarded to the prosecutor's office for their review and a charging decision.
Further, prior to uploading the data to the dashboard the raw information is reviewed by a command officer. Most discrepancies in the data are resolved during this comprehensive case management and review process. However, as the data is manually entered, human error is possible.
- Why do some of the numbers on the dashboard not add up?
There are many reasons for this, please refer to the "tool tips" and Dashboard Guide.
- On the Subject Control and Show of Force page, why do the totals under the Levels of Control not add up to any of the other numbers across the top?
During a Subject Control occurrence, multiple levels of control can be utilized by each person involved. This can result in larger totals under this section.
- On the Subject Control and Show of Force page, why are total occurrences lower than the other total numbers across the top?
During a Subject Control or Show of Force occurrence, multiple Deputies or Corrections Officers could be involved in a single occurrence, and each is required to write their own report under the same incident number. The total occurrences box refers to the single incident that is connected to the Subject Control or Show of Force and does not include whether any other officers were involved during the incident. The "Total Subject Control" and "Total Show of Force" boxes include all officer reports under the associated incident number.
- On the Subject Control and Show of Force page, why is the Show of Force-Weapon data disproportionate?
During a show of force multiple different weapons can be used. This data captures the final/highest level that was utilized before the subject complied to lawful commands.
- Why is the map blank for Show of Forces?
Show of Force incident location is not collected by address and/or zip code. Accordingly, the information needed to create the map is not available.
- How can I obtain open record data?
Please visit Sheriff's Office Freedom of Information Act (FOIA) to submit a request.
