Connecticut Nonprofit Maps

Image of Connecticut State Map - State Senate Districts
With just under one month until election day, we thought one extra advocacy tool would be a welcome opportunity for Connecticut’s nonprofits to reach out to their Representatives and Senators.

To use the maps, we recommend a tablet or computer, but your phone will still allow you to access the maps. Follow the links below to go full screen and optimize your interaction with the map.

How to Use the Maps:

Zoom to your part of the state and find your district on the map. You can then click to view the totals for each district (revenue, assets, people employed).

In addition, you can use the menu on the left to filter through the 12 different categories of nonprofit and populate the map with pinpoints of each organization.

Below you’ll find the maps, methodology used to make the maps, and sources for the data that feeds them.

The data used to populate these maps was accessed using the National Center for Charitable Statistics (NCCS) Enhanced Extract of IRS Financial Data, 2013. NCCS allows users to download data processed by the IRS during calendar year 2013 as submitted on forms 990, 990EZ, and 990PF. The Connecticut files contained 9,872 records and 9,017 after cleaning the combined data set. All data is therefore “as is,” or as it was reported on the forms to the IRS. The number of exempt organizations may seem low and that is because there are actually 18,817 registered orgs in Connecticut, but not all were included in this data set.

You will find two key data features on each map:

Legislative District Tiles
The blue map layer showing the legislative districts has been aggregated by adding the data for each town in the district. When a town is split among multiple districts, we included data for the entire town in each district. To make the maps a useful advocacy tool, the data have not been dis-aggregated according to the lines of each district. All values should be considered estimates, given the potential for inaccuracies in the data. Below are the fields.

The total number of people employed by the nonprofits in the district, which is only reported on Form 990, excluding potential employees of exempt organizations filing forms 990PF and 990EZ (Form 990, Part I, Line 5)
Total reported compensation, salaries, and wages for officers, directors, and employees, excluding the value of insurance and other benefits, which is not reported on from 990EZ (Form 990, Part IX, Lines 5 & 7; Form 990PF, Part I, Line 13)
Total payroll taxes paid as reported on form 990, but excluded from form 990PF and 990EZ (990, Part IX; Line 10)
Total revenue as reported on forms 990, 990PF, and 990EZ (990, Part I, Line12; 990PF, Part I, Line 12; 990EZ, Part I, Line 9)
Total amount of assets as reported on forms 990, 990PF, and 990EZ (990, Part I, Line 20; 990PF, Part II, Line 16; 990EZ, Part II, Line 22)
Total value of grants made, as reported on forms 990 and 990PF, but excluded from 990EZ (990, Part I, Lines 1, 2, 3; 990PF, Part I, Line 2)

Nonprofit Data Points
The points on the map are organized by NTEE category. NTEE is the National Taxonomy of Exempt Entities which categorizes nonprofits based on their social purpose. The National Center for Charitable Statistics has honed the large list down to 12 key groups. Blueprint for Impact has reduced the list to ten types for the sake of map functionality. Higher Education and other Education-based organizations were combined into an “Education” category. Hospitals and other Health-related nonprofits were combined into “Public Health & Hospitals.”

When you click on a point, you can view some basic information about each individual nonprofit in Connecticut. You will find standard address data and some additional content.

The number of years since the IRS ruling on tax-exempt status was provided. In Connecticut, there are many nonprofits that have been tax exempt for over 50 years. Older organizations may be more influential in their community.
The fiscal year for which the nonprofit is reporting the forms 990.
Some data about a particular nonprofit may be unavailable based on the type of form 990 it filed with the IRS.

As an added bonus, explore how Connecticut’s nonprofit sector stacks up nationally.
