Boards may pass and repeal laws, generally called
ordinances. Depending on the state, and the subject matter of the law, these laws may apply to the entire county or to only
unincorporated areas not located within the jurisdiction of a city. The board is also responsible for approving the county budget. County governments may collect state taxes and, in some states, they may also levy taxes, such as property or sales tax. In some states, including
Michigan, and in some
New York counties until recently, county governing boards were composed of township (Michigan) or town (New York) "supervisors". These are the chief elected officials of each civil township. Boards of Supervisors were originally composed of the various town/township supervisors from across the county. This system gave every township one vote on the county board regardless of its population, resulting in less populous townships having influence in decision-making that was disproportionate to their populations. Both Michigan and New York changed how they elected county boards by dividing counties into single member districts, drawn so that each district has more or less the same sized population or with each township's vote weighted by population, under order from the
Warren Court (see
Reynolds v. Sims). In Michigan, the new board model was implemented in 1968. The name "Board of Supervisors" was changed to "Board of Commissioners" in 1970 to avoid confusion with township government (where the term "Supervisor" was still used). In New York, the new boards were called "county legislatures" (and their members, "county legislators"), but not every county has adopted this system. Those that retained the old boards of supervisors after the 1960s assigned each member a proportional vote based on the population represented. ==Executive powers==
