As of the 2020 United States census, the population of the town was 4,772. Blythewood was originally named "Doko", a Native American term for a watering place. The town was named after Doko Depot, which was a stop along the railroad that ran between Charlotte and Columbia. In 1865, this railroad was destroyed by General Sherman. The town was rebuilt, and changed its name to Blythewood in 1877, after a local school called The Blythewood Female Institute. The school was later renamed "Blythewood Academy".
