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.

History

Oldham County was established on December 15, 1823, from parts of Henry, Jefferson, and Shelby Counties.^[7] It was the 74th Kentucky county, and was named in honor of Col. William Oldham of Jefferson County, a Revolutionary War officer.^[8]

Initially, it was mainly a rural county with small, scattered developments in places like Westport which was founded in 1800 and served as the county seat early on. When the Louisville and Frankfort Railroad Company introduced rail lines in the area in the 1850s, many new towns and communities sprang up. Eventually the railroad ceased operating as a form of public transportation, but the more rural nature of the county continued to draw residents away from the metropolitan areas in Jefferson County.^{[citation needed]} Since the early 1970s and the completion of Interstate 71, which connects Oldham County to Downtown Louisville and shopping in Eastern Jefferson County, Oldham County has increasingly become suburban in nature, a natural extension of Louisville's wealthy East End as it ran out of large tracts of undeveloped land.^{[citation needed]}

Geography

According to the United States Census Bureau, the county has a total area of 196 square miles (510 km²), of which 187 square miles (480 km²) are land and 9.2 square miles (24 km²) (4.7%) are covered by water.^[9] It is the 13th-smallest county in Kentucky. The county's northern border with Indiana is formed by the Ohio River.

Oldham County is the most affluent county in the state of Kentucky; most residents work in Louisville and choose to live in Oldham County due to the lack of crime and the nationally recognized school system. North Oldham High School in particular, is ranked very highly among state high schools, having been named a national blue ribbon school of excellence, and ranked in the top 250 best schools in the nation through Us Weekly.^{[citation needed]} 2006 classes at Oldham County High School were reported as to have a teacher:student ratio of 1:15, but that number does not accurately reflect the ratio of a normal class.^{[citation needed]} That number includes, for example, the small classes of five to six students in Behavioral Disorders.^{[citation needed]} The published ratio also includes small classes at the County Career Center, which is located on the same campus.^{[citation needed]} The actual teacher-student ratios are closer to 1:30. Regardless of population swelling and diminishing student-teacher ratios, which have led to a slight decline as of late, Oldham county is still widely recognized as the best public school system in the state.^{[citation needed]}
