The Native American Mattahunt Tribe once inhabited Mattapan in the early 1600's. Since then, a diverse population of Irish, Jewish, and Haitian immigrants has settled here in large numbers. Today Mattapan's population is largely made up of African Americans and immigrants from the Caribbean. A 21,000 square-foot Boston Public Branch Library is being planned adjacent to the Mildred Avenue Middle School and Community Center, making it a resource for the entire community. The Mattapan Economic Development Initiative, a collaboration of city agencies, residents, non-profits, and businesses, was recently established to encourage investment, create jobs, and promote business development in the area.
