According to the portal website, “[the Pratt Center for Community Development believes] everyone, especially those without access to expensive mapping software, should have equal and free access to essential data about their neighborhoods.”
The portal map’s datasets relate to socioeconomics, demographics, crime statistics, the built environment, and more. For instance, a user can see all of the city’s commercial-use properties or chemical bulk storage sites.

Each of these datasets can be layered on the interactive map. The Layer menu appears when the portal is opened but can also be accessed by clicking on its icon on the main toolbar at the top left of the map. Checking one of the boxes in the Layers menu will reveal shading or icons on the map. These components can be selected to show a pop-out box with further information.
Some other features on the main toolbar are the type of base level map, measuring tools, and the option to share the map.
Selecting the Neighborhood Tabulation Areas (NTA) layer will display the borders for different New York City neighborhoods. By clicking within the boundaries of an NTA, users can see detailed information about that area including the population, number of vacant lots, number of schools, and crime statistics.

An instructional video for the portal notes that “[color shaded] layers cannot be turned on simultaneously as visible sets of data invalidate each other.” The data was compiled from a long list of city, state, and federal government agencies as well as some private organizations.
