Sources: HUD 2027 QCT data file (qct_data_2027.xlsx), checked tract by tract against HUD's QCT2027.csv; population from the 2020 Census columns in that file. Properties: HUD's LIHTC database (LIHTCPUB, revised May 28, 2026), monitored properties by 2020 tract; HUD codes Connecticut properties by the former counties, so they cannot be matched to the planning-region tracts.

Small Area DDA ZIP codes
