2025 Boston Population Estimates - Census Tract Level

This dataset includes the City of Boston Planning Department Research Division's population estimates for Boston's population at the 2020 Census Tract level on January 1st, 2025. The Research Division created age-specific population estimates for Boston, its neighborhoods and census tracts. 2019-2023 American Community Survey (ACS) data were used to analyze the Research Division population estimates by demographic characteristics. The Research Division developed these estimates in light of the 2020 Decennial Census and subsequent American Community Surveys undercounts of Boston's population. The Research Division provides annual estimates of Boston's population rectifying this undercount. To view these data interactively at the city, neighborhood, and tract level, please use the Research Division's MyDemographic Viewer tool. To view these data interactively from 1950 to 2035, please use the Research Division's Exploring Neighborhood Change Tool. For more information on the Research Division's motivations and methodology for creating alternate population estimates to the Census Bureau, please see the following documents: A detailed explanation for the motivation for creating these population estimates can be found here. A presentation overview of the undercount of Boston's population can be found here. A detailed explanation of the population estimation methodology can be found here.
