Oldham County is the wealthiest county in Kentucky and 48th wealthiest county in the U.S. and ranks second highest in Kentucky for percent of college educated residences. While the causes for this are complicated, areas east of Louisville have long been popular with wealthy residents, first as summer residences eventually as year-round suburban estates and bedroom communities. Oldham County lies northeast of the best known of these areas, but is still a part of Louisville's East End and a location of choice for Louisvillians who can afford it.
