Maryland Industries

Maryland (MD) shows 10,248,423 workers employed across 650,213 business establishments, covering 924 industries tracked by the Census Bureau County Business Patterns 2023 program. That single-state footprint is a starting point for anyone benchmarking location strategy, evaluating a market for expansion, or simply understanding where jobs concentrate. The single largest employer-industry in Maryland is Health Care and Social Assistance with 403,945 workers — a signal about what kind of labor market and supplier ecosystem the state actually supports.

Beyond the top employer, Professional, Scientific, and Technical Services (301,509) and Professional, Scientific, and Technical Services (301,509) fill out the top three, giving you a quick read on the state's economic base. Payroll dispersion is just as important as headcount: the highest-paying tracked industry (Finance and Insurance) pays $229,740/yr per employee, while the lowest-paying (Educational Services) pays $10,802/yr. That gap tells you how the state's median wage is being pulled up or down by its industry composition — critical context for anyone comparing cost of labor across markets.

Census CBP data does not include profit margins (that comes from IRS Statistics of Income at the national level only), so a full benchmark on any specific NAICS code in Maryland requires combining this state page with the national industry page.
