NE Provenance tracks 1,197,993 properties across 7 Connecticut counties and 133 municipalities — with 430+ intelligence attributes per parcel assembled from 140+ independent data sources. The median Connecticut property dates to 1963, with the oldest on record to 1639.


Connecticut replaced its eight traditional counties with nine planning regions in 2022, making it the only New England state without county-level government. This administrative restructuring complicates property data aggregation — most national data providers still use the old county structure. NE Provenance maps every parcel to both the current planning region and the historical county, maintaining compatibility with legacy systems while reflecting the state's actual governance.
The state's 169 municipalities span a wide range — from dense urban centers like Hartford, Bridgeport, and New Haven to affluent suburban towns in Fairfield County and rural communities in the northeast hills. Connecticut's property stock reflects this diversity: Gilded Age estates, mid-century suburban ranches, historic town centers, and converted industrial buildings all coexist within the state's 5,543 square miles.
Long Island Sound coastline creates significant storm surge and flooding exposure for southern Connecticut communities. The state's position at the convergence of New England and Mid-Atlantic weather patterns produces unique hazard profiles — hurricane tracks that follow the Sound, nor'easters that drive coastal flooding, and ice storms that impact power infrastructure across the inland hills.
