Creating a Safer Community

The city of Memphis has created a Safer Community dashboard page in partnership with the Memphis Police Department (MPD). We are starting with two dashboards - the Weekly Crime Trend Report and the Crime Analytics Dashboard - both utilizing MPD data. We also intend to add data from the courts, the DA, and other community partners as available. 
 The intent of the Weekly Crime Trend dashboard is to track our progress toward our annual goal of reducing crime by 10%, while the Crime Analytics Dashboard takes a deeper look at the crime stats and trends over the past five years. 
 Each interactive dashboard includes key metrics and data that is updated daily or as new data is available. The Crime Analytics dashboard has various ways to slice/filter the data. 
 The city of Memphis believes in transparency and the power of using data to help drive our efforts to create a safer, stronger Memphis. 
 Below is a guide to the dashboard components. The Weekly Crime Trend report can be found here. And the Crime Analytics dashboard can be accessed here.

Crime Analytics How-To Guide

Welcome to the City of Memphis Crime Analytics Dashboard! This dashboard provides details on what, where, and when crimes are committed. The dashboard contains data beginning January 1, 2019, and is updated daily with yesterday’s data. The dashboard is interactive, meaning you can use the “slicers” at the top of the page to filter the visuals. Read on for more information about the dashboard’s components and interactions!

Overview

An offense is classified into 3 levels: crime type, crime category, and crime against, based on the National Incident-Based Reporting System (NIBRS) definitions. For example, the crime of murder is in the category of homicide offenses, which are in the crimes against people category. This dashboard shows all Group A crime types. 

View Summary

Clicking this button will direct you to the summary page of Part 1 crimes this year compared to last year. Use the back arrow on the top right of the page to navigate back to the dashboard homepage. 

Slicers

Slicers are used to filter the data. On this dashboard, you can filter the visuals by year, crime category, Part One/Two designation, Precinct, or all the above! You can also select options from multiple slicers at once (maybe you want to see the total homicides in 2023 in the Crump precinct). For all slicers except Year, you can select multiple options within each slicer by holding the “ctrl” button while you select (maybe you want to see homicides and robberies in 2023 in the Crump precinct). To clear your filters, hover over the right-hand corner of the slicer box and click the eraser icon that appears.  

Tooltips

A tooltip is a pop-up that appears when you hover a visualization. Likewise, anywhere you see an “i” icon, you can hover over it to see more information. Most of the visuals on the dashboard have a tooltip that will provide more information, including a comparison to last year and/or crime type definitions. When the Year slicer is set to the current year, the metric calculations are made on a year-to-date basis, defined as January 1 of the current year through yesterday. When a previous year is selected in the year slicer, the metric calculations will show data for the complete calendar year.
Here's an example of how year-to-date calculations work: if today is June 15, 2024, our year-over-year calculation will show the percent change between January 1, 2024, and June 14, 2024, compared to January 1, 2023, through June 14, 2023.
