User Guide

Toolbar & Navigation


The Toolbar allows you to select which datasets you will view on the map. Select from the Subsidized Housing Database to find specific properties or view sets of subsidized properties by available characteristics.

There are five other categories on the toolbar called Neighborhood Indicators, which includes Demographics, Housing Market and Conditions, Land Use and Development, Neighborhood Services and Conditions, and Renters. Select an indicator from one of these menus to view on the map or export to a table aggregated at the city, borough, or neighborhood level.

The Neighborhood Indicators can be displayed on the map at the same time as property-level information from the Subsidized Housing Database.

Subsidized Housing Database

  • Use the drop-down menu to filter and browse properties in the five boroughs of New York City that currently receive city, state, or federal subsidies.
  • You can refine your search, and thus the properties shown on the map, using the following filters:
    • General (property characteristics including building size, units, and age)
    • Location (property location)
    • Subsidies (properties that have received various types of subsidies)
    • Distress (properties exhibiting physical or financial distress)
  • Each property is represented as a dot on the map. Clicking on a dot will bring up a detailed report about that property, also downloadable as a PDF.

Neighborhood Indicators

  • These drop-down menus allow you to choose indicators by topic at the city, borough, or neighborhood level pertaining to:
    • Demographics (characteristics of the population, e.g. race and ethnicity, income, place of birth, age)
    • Housing Market and Conditions (sales prices, foreclosure rates, tenure)
    • Land Use and Development (building permits, population density, units in the flood zone)  
    • Neighborhood Services and Conditions (school quality, crime rates, commuting characteristics)
    • Renters (cost, affordability, subsidies)

Map View and Table View: The default display is Map View. To change, select Table View, as shown below.

Table View / Tabular Output: The datasets available in CoreData.nyc can be exported in a table or list that can be downloaded as a CSV file.

  • Once you’ve refined your query, click Table View in the upper left hand corner to convert the data displayed on the map into a table.
  • You may either download just your query, or the complete subsidy and housing dataset for further analysis.

Export limitations: Please note that Table View can only display data pertaining to Subsidized Properties and Neighborhood Indicators. While location-based information is captured in the table, CoreData.nyc cannot generate a Table View of Geographic Boundaries or CoreData Visualizations.

Control Panel

The Control Panel is how you control the displayed data. At any time you can expand and collapse the sections as needed, or toggle a layer switch on or off to show or hide the layer on the map. The layers on the Control Panel are Subsidized Properties, Neighborhood Indicators, and Geographic Boundaries.

Layer - Subsidized Properties: By default when you first load CoreData.nyc the “Subsidized Properties” dataset is activated and the filter “Has Subsidies” is enabled.

  • To apply or change the Subsidized Properties filter, click ‘Subsidized Housing Database’ on the Toolbar to change the parameters of what properties are displayed.

Layer - Neighborhood Indicators: After you’ve selected a Neighborhood Indicator from the Toolbar you can further refine the data using the Control Panel. You can select the Year and Region for the indicator. Year and region availability varies by indicator; all available options will appear in the drop-down list.  

Layer - Geographic Boundaries: You can add an additional geographic boundary to the map. The following boundaries are available from the drop-down list:

  • Boroughs
  • Sub-Borough Areas
  • Community Districts
  • City Council Districts
  • Congressional Districts
  • State Senate Districts
  • State House Districts

Troubleshooting: If the data is loading slowly, try turning off one of the datasets by clicking the slider on the Control Panel

The Geographic Boundaries layer is for visual purposes only. Neighborhood Indicator data cannot be attributed to the boundaries displayed in the Geographic Boundaries layer. To find a Neighborhood Indicator for a specific geography, choose from the Region options in the Control Panel.

CoreData.nyc Visualizations

CoreData.nyc Visualizations are custom maps created by NYU Furman Center researchers that highlight timely data and recent data updates. When the CoreData.nyc Visualizations layer is visible, the Subsidized Properties, Neighborhood Indicators, and Geographic Boundaries are turned off. CoreData.nyc Visualizations are not available in table view.

All CoreData.nyc Visualizations are published on furmancenter.org with accompanying analysis. To view, click on the link provided in the map legend.

  • Political and Administrative Districts (Census Tract, Sub-Borough Area, Districts)
  • Physical and Financial Condition (housing code violations and tax delinquency)
