Oneida County is a county in Idaho, a state in the United States. In 2020, about 4,564 people lived here. The main town and biggest city is Malad City. Most people in the county live in Malad City and the area around it called Malad Valley.

History of Oneida County

Oneida County got its name from Oneida Lake in New York. This is because many of the first people who settled here came from that area.

The county was officially started on January 22, 1864. Its first main town, called the county seat, was Soda Springs. This area is now part of Caribou County.

Later, in 1866, the county seat moved to Malad City. This happened because Malad City was growing. It was also on an important road for moving goods and a stagecoach line. This road connected Corinne, Utah, to the mines in Butte, Montana.

When it was first formed, Oneida County was very large. It was one of the biggest counties in Idaho in terms of both land and people. Over time, its size changed many times. Parts of it were given to other territories or used to create new counties. For example, it lost land when Montana Territory and Wyoming Territory were created. New counties like Bear Lake County and Cassia County were also formed from its land.

Even with these changes, the number of people living in Oneida County grew. Many Mormons moved to Idaho's southern border, which helped the population increase. In 1880, Oneida County became the most populated county in Idaho.

However, when Bingham County was created, Oneida County lost many people. Later, in 1913, the creation of Franklin and Power Counties also caused the population to drop. After 1920, the number of people in Oneida County kept going down for about 50 years. Since then, the population has slowly started to grow again.
