Demographics
A Portrait of Carlisle
Carlisle is a rural town of about 15 square miles in northwest Middlesex County, and a comfortable one: more than nine in ten of its homes are owner-occupied, households average 3.0 people, and the median home value tops one million dollars. About one resident in five is 65 or over and about one in four is under 18, so the town skews toward families and long-time owners. Roughly one resident in nine was born outside the United States. Figures below are from the U.S. Census Bureau and the Secretary of the Commonwealth. Follow the source links for the latest.
