The Baltimore Datamind interactive map can be used to create and customize maps in order to compare data across neighborhoods, create community profiles, and combine neighborhood data and community resources and assets in the same map. Learn how to find an area, visualize data and share your findings.
How to Use the Map
Find an area by zooming and clicking a neighborhood, or entering an address or zip code.
Neighborhood names appear on the Datamind map homepage. Each neighborhood is outlined by black boundary lines that represent the Community Statistical Areas (CSAs).
Select a Neighborhood
Simply click on the CSA you are interested in and the area of interest will be highlighted in a blue outline; a dialogue box with population data will appear. You can click the “zoom to” link in the bottom left of the dialogue box to automatically zoom to that CSA or you can use the map’s zoom in tool (+ sign) on the left side.
The + and – symbols on the left side of the map can be used to zoom in and out of specific areas to guide your way through the map.
To clear a currently selected location, and return to the home page, simply click the “zoom to Baltimore” home button below the + and – zoom options.
To clear your currently selected data layer, simply refresh the page using your browser’s refresh button.
CSAs are boundaries created by the Baltimore City Planning Department based on census tracts. There are 55 CSAs in Baltimore City. CSA’s may cut through neighborhoods and zip codes. Learn more about CSAs and view a community profile for each CSA from BNIA.
Example: 1723 S. Charles Street
Type an Address or Zip Code
To choose a location by an address or zip code, type the street address or the zip code in the address bar at the top of the screen and click “search.” The city and state will be set by default to Baltimore, MD.
You can customize the map by adding data layers and sites to visualize your data. See all of the available data layers and sites and learn how others are using the map.
Adding a Data Layer
The left sidebar contains nine different categories, or “data layers”: Demographics, Health, Education, Crime and Safety, Housing, Economic and Workforce Development, Transportation, and Neighborhood Health and Environment. Clicking on each of these allows you to see the sub-categories within each data layer and/or data indicators within them. The Demographics category is chosen by default.
Once a data layer is chosen, you can click on each subcategory to view the data layers and indicators that are available.
Start by clicking on Demographics (the data layer), then click Age (the sub-category), and lastly click 25-64 (the data indicator). Then population data for city residents ages 25 to 64 will be displayed on the map.
You can click on a CSA and a dialogue box will appear with more detailed age information for that neighborhood as well as Baltimore City overall.
The map legend is displayed in the bottom left corner of the map, below the zoom tools menu. The data legend shows the ranges of the data values in numbers or percentages.
Additional controls are at the top left of the map, above the zoom tools menu.
The top most control button is “Hide or Show Panel,” which collapses the data layers menu from the left hand side of the screen.
To bring the data layers panel back, just click on “Hide or Show Panel” again.
The bottom control button “Add or remove point features,” opens up a Map Options panel on the left side of the map, where Hospital, School and Library sites can be selected. Click on the on/off button to show or hide point data for hospitals, schools and libraries.
In order to return to the data layers panel, just click the middle control button, “Map Layers.”
Sites are simply places and/or community resources and assets.
Navigate to sites by selecting the bottom control button “Add or remove point features.” This opens up a Map Options panel on the left side of the map, where Hospital, School and Library sites can be selected.
Clicking on the menu button to the left of the site will turn the sites on or off.
Example: clicking “on” for the hospital sites displays all hospitals located in the map.
Hovering over a site will bring up a dialogue box with more detailed information.
Clicking on a site will bring up a dialogue box with a “zoom to” option in the bottom left corner.
