As of the 2010 census, the population was 165,676. The county was created in May 1785 from portions of Hartford County and New London County. Middlesex County is included in the Hartford-West Hartford-East Hartford metropolitan statistical area known as Greater Hartford. As with all eight of Connecticut's counties, there is now no county government and no county seat. In Connecticut, towns are responsible for all local government activities, including local police, fire and rescue, snow removal, and schools. In a few cases, neighboring towns will share certain resources, e.g. water, gas, etc. Middlesex County is merely a group of towns on a map, and no longer has any particular authority."
