2000 census record

Researchers William P. O'Hare and Kenneth M. Johnson described the county as typical of the northern Great Plains in being very thinly settled, almost fully dependent on agriculture, and lacking in urban areas. They noted that income can fluctuate substantially from year to year, depending on rainfall (which affects harvest yields) as well as grain and cattle prices, and that the 2000 Census recorded low incomes in 1999 after several years of drought. Also, the presence of Hutterite colonies in the county depresses per capita incomes because Hutterite families have significantly more children than the general population.
