Oldham County is the wealthiest county in Kentucky and 47th-wealthiest county in the U.S. (and 37th in the U.S. by median income) and ranks as the most educated county in Kentucky. 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.
