The Valley Community Index is a triennial profile of life in the Lower Naugatuck Region of Connecticut (defined as the towns of Ansonia, Beacon Falls, Derby, Naugatuck, Oxford, Seymour, and Shelton).

The 2025 Valley Community Index was developed through a collaboration of community partners and stakeholders. Drawing from local data, research, and the voices of community members and professionals, the Index offers key insights into the social, economic, and health factors that impact Valley residents. Nonprofits, towns, cities, and other organizations use the 2025 Valley Community Index to guide strategic planning, develop programs, secure funding, and advocate for the resources that help our communities thrive.

Prior editions of the Valley Community Index from 2016, 2019, and 2022 are also available on the DataHaven website.
