With support from the Massachusetts Secretary of The Commonwealth, the UMass Donahue Institute (UMDI) in 2015 produced population projections for all Massachusetts municipalities using a model developed by Dr. Henry Renski of UMass Amherst. In 2018, with support from the Massachusetts Department of Transportation (MassDOT) and in collaboration with Massachusetts Regional Planning Associations, UMDI updated these projections with more recent inputs to inform MassDOT’s Socio-Economic Projections for 2020 Regional Transportation Plans. The resulting “UMDI-DOT Vintage 2018” projections are posted here for public-use.
The UMDI-DOT V2018 population projections are available by sex and 5-year age group for each Massachusetts city and town, each Massachusetts county, and eight distinct Massachusetts study regions at 5-year intervals to 2040. See the full list of downloads below.
