About Butte County

Population 2,500 residents
County Seat Arco
Established 1917

Butte County is located in southeastern Idaho, covering approximately 2,234 square miles of high desert and mountainous terrain. The county seat is Arco, which holds the distinction of being the first city in the world to be lit by atomic power on July 17, 1955. With a population of approximately 2,500 residents, Butte County is one of Idaho's least populous counties, offering wide-open spaces and stunning natural landscapes. The county is home to Craters of the Moon National Monument and Preserve, a vast volcanic landscape featuring lava flows, cinder cones, and sagebrush steppe.

The Idaho National Laboratory (INL), one of the nation's premier nuclear research facilities, occupies a significant portion of the county and serves as the primary economic driver. Butte County was established in 1917 from parts of Bingham, Blaine, and Jefferson counties. The County Recorder's office, located at 248 W Grand Ave in Arco, maintains land records and property documents.

The Butte County Clerk's office, also at 248 W Grand Ave, handles court records, marriage licenses, and election administration. The Butte County Assessor, situated at the same address in the Butte County Courthouse, manages property assessments and tax rolls. The county's history is deeply tied to nuclear energy research, ranching, and mining, with the Big Lost River valley providing limited agricultural opportunities in an otherwise arid environment.

The Sheriff's Office handles law enforcement duties in the unincorporated areas, while the Arco Police Department serves the city of Arco.

Economy & Demographics

Butte County's economy is dominated by the Idaho National Laboratory (INL), which employs thousands of workers in nuclear energy research, national security programs, and advanced energy systems development. The INL is the largest employer in the region and drives significant economic activity through direct employment and contracted services. Many INL employees live in neighboring counties and commute to the site, but the facility's presence shapes the entire regional economy.

  • Median household income in Butte County is estimated at approximately $55,000, which is influenced by the mix of government employment, ranching operations, and service sector jobs.
  • Tourism provides seasonal economic activity, with visitors to Craters of the Moon and hunters accessing public lands.

Beyond the INL, the county's economy relies on ranching, agriculture in the Big Lost River valley, and tourism related to Craters of the Moon National Monument. The county's population remains small and relatively stable, with minimal commercial development outside of Arco. Unemployment rates in Butte County typically track below the state average due to stable government employment, though private sector job opportunities are limited.

The county's tax base benefits significantly from the INL facilities and infrastructure, though much of the laboratory land is federally owned. The lack of significant retail or manufacturing limits economic diversification, making the county highly dependent on continued federal investment in nuclear research. Recent economic development efforts have focused on outdoor recreation infrastructure, small business support in Arco, and maintaining quality of life for INL workforce families.

The county's remote location and sparse population present challenges for business development and economic expansion beyond existing sectors.
