How Local Government Operates in Indiana: Bifurcated: 3 Commissioners & 7-Member County Council
Executive power is held by a 3-member Board of County Commissioners, while legislative and fiscal budgeting authority is held by a separate 7-member County Council. Marion County operates under the Unigov consolidation with Indianapolis.
Bifurcated County Government: Commissioners vs. County Council
Unlike states with a unified county board, Indiana divides county authority between two distinct elected bodies.
Under Indiana Code Title 36, county government in 91 non-consolidated counties is intentionally bifurcated to prevent the concentration of municipal power.
The Board of County Commissioners consists of three commissioners elected from districts (who must reside in their district but are voted on county-wide). The Commissioners act as the executive and administrative body: they manage county roads, sign contracts, oversee county buildings, and direct emergency management.
However, the Commissioners cannot adopt county budgets or set property tax rates. That exclusive power belongs to the County Council—a 7-member legislative body (4 elected from districts, 3 at-large) that appropriates all county funds and sets salary schedules for all county personnel.
In 1970, the Indiana General Assembly enacted "Unigov," consolidating the City of Indianapolis with Marion County under an elected Mayor and 25-member City-County Council.
Calumet Region to the Ohio River Hills: Indiana’s Geographic Axes
Indiana counties span from the industrial Lake Michigan coastline to karst limestone hills along the Ohio River.
In northwest Indiana, Lake and Porter counties form the "Calumet Region," heavily integrated into the Chicago metropolitan economy, featuring massive steel mills, refineries, and the Indiana Dunes National Park along Lake Michigan.
Central Indiana (Marion, Hamilton, Hendricks, Johnson) is characterized by flat, glaciated till plains with fertile loam soils supporting expansive agriculture and suburban growth, with Hamilton County ranking among the highest-income counties in the Midwest.
Southern Indiana counties (Monroe, Lawrence, Brown, Crawford) lie in the unglaciated interior plateau, renowned for the Indiana Limestone belt (which supplied stone for the Empire State Building and Pentagon) and deep karst cave systems.
80 Indiana counties observe Eastern Time, while 12 counties (6 in the northwest near Chicago and 6 in the southwest near Evansville) observe Central Time.

Data Sources & FIPS Codes
Indiana uses state FIPS code 18; each county adds a three-digit code to form the five-digit FIPS (now INCITS 31) identifiers in the table. Populations are 2020 Census counts and land areas come from the Census Gazetteer. The map above is drawn from the Census Bureau's generalized 2017 cartographic boundary file (1:10,000,000), so it suits overview and printing, not parcel-level or legal boundary questions; for those, check the local assessor or GIS office.
