Share of Residents that live within 0.5 walking distance miles of an MBTA subway station
Description
Measuring the number of transportation options that the average Cantabrigian has available is an indicator of overall freedom of movement. This indicator estimates the share of the total Cambridge population that resides within a half-mile walking distance of an MBTA subway station. Note that a new Green Line station at Union Square in Somerville, within walking distance of some Cambridge residents, opened in 2022.
Data Source
2010 and 2020 Census; Annual Housing Starts data from CDD
Methodology
Population counts by Census block were applied to 1-acre hex grid cells covering the City. For non-Census years, changes in population were estimated based on the net change in housing units listed in annual Housing Starts data, and these changes were applied to the hex grid cells at the location of the development projects. The percentage of the population located within a half-mile walking distance buffer from T stations was then calculated.
