In October 2018 the Portland Police Bureau initiated a new process to collect, store, and track information related to gun violence. This dashboard is a representation of shooting incidents where a firearm was discharged and reported to the Portland Police Bureau. It can be filtered based on firearm-related injuries, but does not include incidents with a firearm-related suicide nexus, attempted or completed. Gun violence data prior to 2019 was not tracked using the same criteria and is not available for comparison.
The report has been customized to work on personal computers, smart phones and tablets. For the best experience, it is recommended you use a desktop or laptop computer.
The Portland Shooting Incidents Dashboard is an interactive data visualization. This interactivity allows users to filter the information based on the questions they are hoping to answer with this dataset. An overview of the pre-built filters is included below.
The first tab provides a comparison of shooting incidents from 2019 to the most current completed month. Those that occurred outside of Portland City Limits may be reported and/or investigated by the Portland Police Bureau, and are included in month-to-month and yearly comparisons. However, these incidents are not included in the Precinct Comparison chart.
The second tab is an interactive report that shows shooting events according to the neighborhood they occurred in. Incidents that occurred outside of Portland City Limits may be reported and/or investigated by the Portland Police Bureau, and are included in month-to-month comparisons, however, they are not displayed on the Neighborhood Map.
Note: Shooting incident data is subject to change as more information is received. The report is updated approximately 15 days after the end of the month.
Date Filter: The Date Filter is the primary selection tool for the date range. The dropdown filter defaults to the most recent 12 month period. To change the months in view, hit the down arrow found in the “Filter by Report Date:” box and select the check boxes next to the corresponding months/years you would like to view. There is no limit to the number of months you can select.
Click the "Apply" button at the bottom of the filter to save your selections. All visuals will update accordingly, with the text box next to Date Filter displaying the selected date range.
Neighborhood Map Interface: The Neighborhood Incidents map is an outline of all Portland neighborhoods using the Portland Police Bureau boundaries. The map dynamically updates based on selected filters. Darker colors signal a higher number of reported offenses. The minimum and maximum values on the color scale adjust based on the other filters. Hover the mouse over a shape to get basic information about that neighborhood, including its name, coalition, and the count for all selected offenses.
The map can also be used to filter results in the different tables and charts. To filter statistics by neighborhood, select the neighborhood on the map. Multiple neighborhoods can be selected by dragging the mouse when clicking or holding down the CTRL button on the keyboard when clicking the neighborhoods.
A link is provided to instructions on finding the neighborhood of a specific location on PortlandMaps.com. Use the text box just above the map to highlight the neighborhood’s location on the map.
TIP: Just using the “highlight” function does not filter by that neighborhood. After a neighborhood is highlighted, make sure to click on that neighborhood shape to filter the results.
Toolbar: The toolbar, located at the bottom of the visualization, contains several buttons that assist in the analysis of the data.
The “Undo” and “Redo” buttons (left and right arrows) become active when the above filters are applied to the report. They operate just like the Undo and Redo buttons in other programs such as Microsoft Word.
The “Reset” button (left arrow with bar) reverts all filters back to their original setting when you first visited the page. This is a great way to start with a “clean slate” after clicking several filters.
The “Download” button (down arrow contained in rectangular box) allows users to save a static version of the visualization. This option is great for printing out copies of the map to share at meetings or to include in a presentation.
“Get the App” takes you to a download page to acquire a Free Trial of Tableau Desktop. This is not necessary, or recommended, to fully analyze and view the report.
“PDF” allows users to export the report, with all of the filters you set, as a PDF. The options dialogue allows custom scaling and paper size options. When choosing to export as PDF, make sure to keep the layout as portrait and content as “this dashboard.”
“Image” creates a .png file of the report with all of the selected filters.
Tableau is the name of the software used to create this report visualization.
