Idaho's unemployment rate fell to 3.8 percent in March with 5,400 workers finding jobs in the largest one-month increase on record.
The Idaho Department of Labor in a news release Friday says total employment in the state also set a record by going above 757,000 for the first time.
The agency says the state's unemployment remained at a seven-year low as businesses expanded payrolls.
The agency also says the percentage of working-age adults with jobs or looking for work rose to 63.5 percent.
Officials say that's the highest level since December 2013 and a sign of increased optimism about job prospects.
Over the last year, Idaho employers have added nearly 20,000 workers.
