In recent years, Scappoose has increasingly become a "bedroom" community of Portland, Oregon, with many commuting to jobs in the city. Dairies, farming, and logging played an important role in the early years of Scappoose's history. In the more recent past, several factories existed in the community and provided jobs. The town was home to a shoe factory, two candle factories, and a Steinfeld's Sauerkraut factory. The area still has gravel mines and the West Coast Shoe factory. Scappoose is also the home of Oregon Aero.
