Knox County produced about $2,633 million of goods and services in 2024, which is 2.7% of the combined output of the 16 counties of Maine that BEA reports (about 3.0% of the state's population lives here), and ranks it 9th of 16 on that measure. Per resident that is $64,206, 10% below the state average; the average for all counties of the state taken together is $71,460. In current dollars output grew 3.8% from 2023 to 2024, before adjusting for inflation.
BLS counts 16,874 jobs located in Knox County on average in 2024, spread over 2,289 employer sites (about 7 jobs per site). That is 0.41 jobs for every resident, above the 0.39 of the typical county in Maine, 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 $55,720, 9% below the average of all counties in the state ($55,720 against $61,512). 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 fell 1.4% from 2023 to 2024.
The three largest private industries are retail trade (21.8% of private jobs, $39,043 a year on average), health care and social assistance (19.6% of private jobs, $70,584 a year on average), accommodation and food services (14.6% of private jobs, $32,897 a year on average). Together they hold 56.0% of private-sector jobs. Among industries with at least 3% of jobs, the best paying is professional and technical services at $89,706 a year, followed by health care and social assistance ($70,584). The county is specialised in an industry: retail trade (1.7 times the US share, 2,820 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 ($32,897). Jobs there are plentiful but the pay is lower than the headline average suggests.
In 2026M09 the unemployment rate in Knox County was 3.2%, about the same as the average of the state's counties (3.2% against 3.1%).
