The purpose of this needs assessment is to investigate the needs, interests, and opinions of mature residents of Marshfield, Massachusetts, relating to their aging experiences and needs for age‐related services. On behalf of the Marshfield Council on Aging (COA), this assessment was conducted by the Collins Center for Public Management and the Gerontology Institute of the McCormack Graduate School at UMass Boston. The focus of this report is on Marshfield residents aged 60+ (referred to here as “Seniors”) and residents aged 45‐59 (referred to here as “Boomers”). Information about these two age groups was obtained both through the U.S. Census Bureau, and through a sample survey designed and conducted in support of this project. Two focus groups were also conducted to obtain feedback on the results and generate recommendations. The content of this report will be useful to the Marshfield COA, other town offices, organizations that provide services within Marshfield (including the local public transportation service provider, GATRA), advocates, and community members.
