Oldham County is a county located in the north central part of the U.S. state and commonwealth of Kentucky. As of the 2020 census, the population was 67,607.[1] Its county seat is La Grange.[2] The county is named for Colonel William Oldham.
Oldham County is part of the Louisville/Jefferson County, KY–IN Metropolitan Statistical Area.
Oldham County is the wealthiest county in Kentucky[3] and 47th-wealthiest county in the U.S.[4] (and 37th in the U.S. by median income[5]) and ranks as the most educated county in Kentucky.[6] While the causes for this are complicated, areas east of Louisville have long been popular with wealthy residents, initially as summer residences and eventually as year-round suburban estates and bedroom communities. Oldham County lies northeast of the best known of these areas, Anchorage, just outside Louisville's pre-merger East End.
