Virginia is composed of a mixture of 95 counties and 38 independent cities. Maryland, Missouri and Nevada are each composed entirely of counties, except that each also has exactly one independent city: Baltimore, St. Louis, and Carson City, respectively. The District of Columbia is a single federal district. All of the above 135 exceptional cases are reckoned as county equivalents. The number of counties (or equivalents) per state ranges from the three counties of Delaware, to the 254 counties of Texas. In New England, where the town model predominates, several counties have no corresponding local governments, existing only as historical legal and census boundaries. These are the counties of Connecticut and Rhode Island, as well as 8 of Massachusetts' 14 counties. In all, the 50 states consist of 3,141 counties and equivalents. Adding the District of Columbia gives 3,142. Similarly, the Census Bureau treats 100 subdivisions of the territories of the United States as county equivalents.
