Decatur County, Indiana: Government, Services & Demographics

Decatur County sits in the southeastern corner of Indiana, a compact 373-square-mile county anchored by the small city of Greensburg — a place whose water tower, for decades, grew a tree from its roof, which became a genuine point of regional pride and a minor tourist attraction. This page covers the county's governmental structure, population characteristics, major economic drivers, and the range of public services available to residents. Understanding how Decatur County operates within Indiana's 92-county framework helps clarify what residents can expect from local government and where state-level authority begins.

Definition and Scope

Decatur County was established by the Indiana General Assembly in 1821, carved from unorganized territory as the state's settlement pushed southeastward. The county seat, Greensburg, holds the county's administrative core and is home to the Decatur County Courthouse, where the elected Board of County Commissioners, the County Council, and a roster of independently elected row officers — Assessor, Auditor, Recorder, Sheriff, Treasurer, Surveyor, Coroner, and Clerk of Courts — carry out the business of local governance.

The county government operates under Indiana Code Title 36 (Local Government), which establishes the structure for all 92 Indiana counties. The three-member Board of Commissioners holds executive and administrative authority: they approve contracts, manage county property, set tax rates within state-defined limits, and oversee departments. The seven-member County Council controls appropriations, setting the actual budget that the Commissioners administer. This two-body structure is the standard model across Indiana's non-consolidated counties, and it can produce productive tension — the Commissioners propose, the Council funds, and neither can act entirely without the other.

Scope and limitations: Information on this page applies specifically to Decatur County's governmental jurisdiction and geographic boundaries. Federal programs administered locally (such as USDA Rural Development grants) and state agency field offices located in the county fall under separate oversight structures. Municipal governments within Decatur County — including Greensburg, Westport, and St. Paul — operate under Indiana's city and town statutes, which are distinct from county government authority. This page does not cover the full range of state-level Indiana policy; the Indiana Government Authority covers Indiana's state agencies, legislative process, and executive branch structure in depth, making it the primary resource for questions that extend beyond Decatur County's borders.

How It Works

Decatur County's population was estimated at approximately 26,500 residents as of the 2020 U.S. Census, a figure that has remained broadly stable over the preceding decade (U.S. Census Bureau, 2020 Decennial Census). Greensburg itself accounts for roughly 11,400 of those residents, with the remainder distributed across smaller towns and rural areas.

The county's economic character is shaped by two forces: agricultural land and manufacturing. Honda Manufacturing of Indiana, LLC, operates a major assembly plant in Greensburg that produces the Honda Civic; the facility employs approximately 2,500 workers and represents one of the largest single private employers in southeastern Indiana (Honda Manufacturing of Indiana). That plant's 2008 opening fundamentally shifted the county's employment base from purely agricultural toward advanced manufacturing, a transition visible in commuter patterns, housing demand, and vocational training priorities at Decatur County schools.

The county's agricultural land, classified primarily as Class A and B soils by the USDA's Natural Resources Conservation Service, supports corn, soybean, and hog production. The Decatur County Soil and Water Conservation District coordinates with the Indiana State Department of Agriculture on conservation programs.

Public services flow through several channels:

  1. Health services: The Decatur County Health Department administers vital records, environmental inspections, and public health programming. Major clinical care flows through Decatur County Memorial Hospital, a 42-bed critical access hospital.
  2. Emergency services: The Decatur County Sheriff's Office handles county-wide law enforcement; municipal police departments cover incorporated areas.
  3. Courts: The Decatur County Circuit Court and Superior Court handle civil, criminal, probate, and family law matters under the Indiana Supreme Court's administrative structure.
  4. Public transit: Limited rural transit options exist through the Decatur County Council on Aging's transportation program, reflecting the limited density typical of Indiana's smaller counties.
  5. Library services: The Greensburg-Decatur County Public Library serves all county residents.

Common Scenarios

Residents interact with Decatur County government most often through property tax assessment and payment, recorded documents (deeds, mortgages, liens), vehicle registration, voter registration, and permit applications for building and septic systems. The Assessor's office determines assessed valuations under Indiana's market value-in-use standard, while the Auditor calculates deductions and exemptions including the homestead credit, which reduces property tax liability for owner-occupied primary residences under Indiana Code 6-1.1-12.

Court filings for probate, small claims, and name changes are processed through the Clerk of Courts. Birth and death certificates are available through the Indiana Department of Health, with the local Health Department serving as a distribution point.

Decision Boundaries

The distinction between county services and municipal services catches residents off guard with some regularity. A Greensburg resident dealing with a zoning dispute is dealing with the City of Greensburg's Plan Commission, not the county's Area Plan Commission — unless the property sits outside any incorporated boundary, at which point the county's jurisdiction applies. Road maintenance follows the same logic: state roads are INDOT's responsibility, county roads fall under the Decatur County Highway Department, and city streets belong to the municipality.

For state-level questions — Indiana driver's licenses, professional licensing, statewide tax obligations, or General Assembly legislation — the Indiana Government Authority resource provides structured coverage of the agencies and statutes that apply statewide.
