The population was 26,180 at the time of the 2020 census. Settlers traded goods with the Indigenous Secatogue tribe for the land that became Dix Hills in 1699. The Secatogues lived in the northern portion of the region during the later half of that century. The land was known as Dick's Hills. By lore, the name traces to a local native named Dick Pechegan, likely of the Secatogues. Scholar William Wallace Tooker wrote that the addition of the English name "Dick" to the indigenous name "Pechegan" was a common practice.
