Last update: Oct. 7, 2026, midnight Source: American Community Survey and Bureau of Labor Statistics Employment Cost Index Data notes: Median household income from the American Community Survey: 1-year estimate where available, 5-year otherwise; county groups are household-weighted. Each year is averaged with the prior year to smooth sampling noise. The latest two years are projections: the ACS figure from two years earlier grown by the two-year change in the BLS Employment Cost Index (December to December), replaced when that ACS year is published. MIBOR (Association) includes Boone County, Brown County, Decatur County, Hamilton County, Hancock County, Hendricks County, Johnson County, Madison County, Marion County, Montgomery County, and 4 more.
