General Info
Named for the Yellowstone River, Yellowstone County was founded in 1883 with Billings selected as the county seat. The area was originally home to Native Americans until lands were opened for settlement. Railroad development provided the means for dramatic growth and between 1900 to 1910, its population soared from 6,212 to 22,944. Early industry was led by agriculture as many residents raised cattle, shipped wool and refined sugar from local sugar beet farms. The area has now grown to a popular recreational destination as many historical sites are available throughout the county that offer visitors a glimpse of its colorful past. Today Yellowstone County is home to approximately 144,797 residents.
