Known for its rich history, a range of scenery and world-renowned healthcare, Massachusetts has a number of qualities that appeal to retirees. Seniors ages 65 and older account for 17%, nearly 1.2 million, of the state’s 7 million resident population. Though most of the state’s best healthcare, such as Massachusetts General Hospital and Tufts Medical Center, can be found in and around the Boston area, Massachusetts’ smaller square mileage means access is easier than in many larger states.
