They all live in Tulsa, Oklahoma

"The Greasers live on the East side, have long hair, hang out at the Dingo and Jay's, do not have alot of money, like Elvis, wear jeans and leather, fight cleaner then the Socs, and are open about their emotions." Ch.2

The SOCS live on the West side which is the upper middle class rich area of Tulsa.
