Connecticut Data Collaborative combined several sources of business data to create a master list. By matching business entities from several sources we were able to create a list of about 100,000 business with an industry code (NAICS). These businesses are mapped according by Sector (2 digits) and Subsector (3 digits). The purpose of this map is to allow anyone to explore business cluster patterns. Experiment with zoom for better results.

This is not an exhaustive map of businesses in Connecticut. These are only businesses that we were able to match from several sources: the CT Secretary of the State, Dun & Bradstreet, and other public data sources. Each dot represents the business registration address or mailing address as filed with the Secretary of the State.
