The Municipal Cost Index (MCI), developed exclusively by American City & County, is designed to show the effects of inflation on the cost of providing municipal services. State and local government officials rely on American City & County‘s Municipal Cost Index to stay on top of price trends, monitor price increases for commodities, make informed government contract decisions and plan budgets intelligently. Since 1978, readers have loyally referred to the Municipal Cost Index to determine the cost of inflation and, hence, the rising cost of doing business as a local government.
