21.2% of all households were made up of individuals, and 3.0% had someone living alone who was 65 years of age or older.

There were 16.7% of families and 24.1% of the population living below the poverty line, including 27.5% of under eighteens and none of those over 64.

During the 19th century, Deg Hit'an Athabascan people had summer fish camps in the area.

The village was often confused with Russian Mission on the Yukon, so in the 1960s the name was changed to Chuathbaluk, which is derived from the Yup'ik word Curapalek, meaning "the hills where the big blueberries grow."

By 1929, the site was deserted, although Russian Orthodox members continued to hold services at the mission.
