Consulting

Employment in professional, scientific, and technical consulting services is expected to increase by 7.5 percent by 2034, according to the U.S. Department of Labor (DOL). It is the second-fastest growing sector for the 2024–34 prediction period. The DOL reports that “businesses will continue to need expertise and advice on how to address complex challenges such as adopting new technologies, incorporating sustainability practices, complying with regulations, managing global supply chains, and more. Sustained demand for consulting services in market research and analysis and management strategy should also support employment.”

Revenues in the global consulting industry reached $1 trillion in 2024, according to The Business Research Company. Industry revenue is expected to exceed $1.3 trillion by 2029. The market research company says that “growth in the historic period can be attributed to globalization, technological advancements, outsourcing back-end operations to low-cost economies, increasing investments in research and development, regulatory reforms in the financial sector, and public private investments.”

There were one million management consulting firms in the United States in 2025, according to industry research publisher IBISWorld. There are four major consulting sectors: management/strategy, financial, information technology, and human resources/staffing. Some firms specialize in only one of these areas, while others may provide expertise in all or several of these sectors—or in additional areas.

The U.S. management consulting sector employs more than three million workers, according to IBISWorld. Employment settings for management consultants breaks down like this (according to the DOL):

• professional, scientific, and technical services firms: 34 percent
• government: 17 percent
• self-employed: 14 percent
• finance and insurance: 13 percent
• management of companies and enterprises: 4 percent
