Saint Mary's County is a county of Maryland with 115,126 residents. Its economy produced $10,446 million in 2024 (ranked #9 of 24 counties) and had 49,113 jobs with an average annual pay of $85,381 (#3 for pay). The unemployment rate was 3.0% in 2026M09. It is part of the Lexington Park, MD metropolitan area (central county).
Saint Mary's County produced about $10,446 million of goods and services in 2024, which is 1.9% of the combined output of the 24 counties of Maryland that BEA reports (about 1.9% of the state's population lives here), and ranks it 9th of 24 on that measure. Per resident that is $90,735, 3% above the state average; the average for all counties of the state taken together is $87,984. In current dollars output grew 6.2% from 2023 to 2024, before adjusting for inflation.
BLS counts 49,113 jobs located in Saint Mary's County on average in 2024, spread over 2,185 employer sites (about 22 jobs per site). That is 0.43 jobs for every resident, above the 0.40 of the typical county in Maryland, 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 $85,381, 11% above the average of all counties in the state ($85,381 against $76,898). 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 3.2% from 2023 to 2024.
The three largest private industries are professional and technical services (35.7% of private jobs, $112,202 a year on average), retail trade (14.6% of private jobs, $35,459 a year on average), health care and social assistance (13.3% of private jobs, $74,230 a year on average). Together they hold 63.7% of private-sector jobs. Among industries with at least 3% of jobs, the best paying is professional and technical services at $112,202 a year, followed by administrative and waste services ($81,811). The county is specialised in an industry: professional and technical services (3.4 times the US share, 11,705 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: retail trade ($35,459), accommodation and food services ($24,723). Jobs there are plentiful but the pay is lower than the headline average suggests.
In 2026M09 the unemployment rate in Saint Mary's County was 3.0%, 14% below the average of the state's counties (3.0% against 3.5%). The labour force (people working or looking for work) numbered 57,828. Over the last 12 months it ranged from 3.0% (2025M12) to 4.2% (2026M02); the latest month is preliminary and BLS revises it. These county rates are not seasonally adjusted, so compare the same month across years.
The median household income was $119,446 (ACS 2020–2024), 15% above the state median ($119,446 against $103,678). None of the largest places of the guide has this as its main county, which usually means a smaller or more rural county; the figures above still describe the whole county.
