Jefferson County is a county of Idaho with 33,154 residents. Its economy produced $1,366 million in 2024 (ranked #18 of 44 counties) and had 9,658 jobs with an average annual pay of $46,365 (#34 for pay). The unemployment rate was 2.7% in 2026M09. It is part of the Idaho Falls, ID metropolitan area (outlying county).
Jefferson County produced about $1,366 million of goods and services in 2024, which is 1.1% of the combined output of the 44 counties of Idaho that BEA reports (about 1.7% of the state's population lives here), and ranks it 18th of 44 on that measure. Per resident that is $41,195, 38% below the state average; the average for all counties of the state taken together is $66,702. In current dollars output grew 1.3% from 2023 to 2024, before adjusting for inflation. The gap between its output rank (18th) and its output-per-resident rank (39th) shows that population is large relative to the value of what is produced here.
BLS counts 9,658 jobs located in Jefferson County on average in 2024, spread over 1,180 employer sites (about 8 jobs per site). That is 0.29 jobs for every resident, below the 0.35 of the typical county in Idaho, which tells you whether the county is a place people mostly commute to for work or a place they commute from. The average annual pay per job was $46,365, 21% below the average of all counties in the state ($46,365 against $58,412). Average pay is total wages divided by jobs, so it is pulled up by high earners and counts part-time jobs as whole jobs; it is not the pay of a typical worker. The number of jobs rose 23.7% from 2023 to 2024.
The three largest private industries are health care and social assistance (27.5% of private jobs, $50,538 a year on average), construction (16.4% of private jobs, $53,088 a year on average), manufacturing (14.8% of private jobs, $58,495 a year on average). Together they hold 58.7% of private-sector jobs. Among industries with at least 3% of jobs, the best paying is manufacturing at $58,495 a year, followed by wholesale trade ($56,639). The county is specialised in several industries: agriculture, forestry, fishing (11.0 times the US share, 861 jobs); construction (2.5 times the US share, 1,250 jobs); health care and social assistance (1.5 times the US share, 2,100 jobs). A location quotient above 1 means an industry employs a larger share of workers here than in the whole country, so these are the industries where local employers compete hardest for skills. Several of the biggest employers pay well below the county average: accommodation and food services ($13,836). Jobs there are plentiful but the pay is lower than the headline average suggests.
In 2026M09 the unemployment rate in Jefferson County was 2.7%, 17% below the average of the state's counties (2.7% against 3.3%).
