Litchfield County is a county located in the northwestern corner of the U.S. state of Connecticut. As of the 2010 census, the population was 189,927. Litchfield County has the lowest population density of any county in Connecticut and is geographically the state's largest county.
As is the case with all eight counties in Connecticut, there is no county government; there is no county seat: in Connecticut, each town is responsible for all local services such as schools, snow removal, sewers, fire department and police departments. However, in some cases in rural areas, adjoining towns may agree to jointly provide services or even establish a joint school system.
