The high-tech industry is a broad category of businesses that rely heavily on scientific research, engineering, and technology development to create their products and services. What sets these industries apart is not just that they use technology, but that they employ an unusually high concentration of workers in science, technology, engineering, and mathematics (STEM) roles. The sector spans everything from software development and semiconductor manufacturing to pharmaceuticals and aerospace.
How the Government Defines High Tech
The U.S. Bureau of Labor Statistics uses a straightforward method to classify an industry as high tech: it looks at the share of workers in STEM occupations. If a goods-producing industry has a STEM workforce share greater than 18.5 percent, or a service-providing industry exceeds 14.7 percent, it qualifies. Those thresholds represent roughly two and a half times the national average for each category. For context, STEM workers make up about 7.4 percent of all goods-producing jobs and 5.9 percent of all service-providing jobs nationwide, so high-tech industries employ STEM talent at rates far above the norm.
This definition captures a wider range of industries than most people expect. It’s not limited to companies building apps or designing chips. Pharmaceutical manufacturing, medical device production, aerospace engineering, and scientific research services all meet the threshold. So do industries like oil and gas extraction, where geological engineers and data analysts make up a large share of the workforce.
Major Sectors Within High Tech
When people say “tech,” they usually mean software companies and internet platforms. That’s a big piece, but the high-tech umbrella covers several distinct sectors:
- Software and IT services: Companies that build applications, cloud platforms, cybersecurity tools, and data infrastructure. This is the most visible part of the industry and includes everything from massive enterprise software firms to small startups.
- Semiconductors and hardware: The companies that design and manufacture the chips, processors, sensors, and devices that power modern electronics.
- Telecommunications: Firms that build and operate wireless networks, broadband infrastructure, and communications equipment.
- Aerospace and defense: Manufacturers of aircraft, satellites, rockets, and the navigation and guidance systems inside them. These companies employ large numbers of mechanical, electrical, and systems engineers.
- Pharmaceuticals and biotechnology: Drug development and biotech research require enormous R&D investment and teams of chemists, biologists, and data scientists.
- Scientific and technical consulting: Firms that provide engineering, environmental, or computer systems design services to other businesses and government agencies.
The boundaries shift as technology reshapes older industries. Electric vehicle manufacturing, clean energy technology, and artificial intelligence development are pulling more companies into the high-tech classification as their STEM workforce share grows.
Why High-Tech Pay Is Significantly Higher
One of the most notable features of the high-tech industry is the wage premium it offers. The median salary across tech occupations is an estimated $112,805, according to CompTIA’s analysis of federal labor data. That figure is more than double the median wage across all U.S. occupations. The gap reflects the specialized skills these roles demand and the intense competition among employers to hire and retain technical talent.
The premium holds across experience levels, though it widens considerably for senior and specialized roles. A mid-career software engineer, data scientist, or cybersecurity analyst typically earns well above the national median, while entry-level positions in tech support or quality assurance start closer to the broader workforce average but still tend to outpace comparable non-tech roles.
Job Growth Compared to Other Industries
The high-tech workforce is projected to grow about twice as fast as the overall U.S. workforce over the next decade, based on Bureau of Labor Statistics and Lightcast projections. That growth is driven by a few forces: businesses across every sector are adopting more software and automation, cybersecurity threats are increasing demand for security professionals, and data-driven decision making is creating new roles that didn’t exist a decade ago.
This growth isn’t confined to traditional tech hubs. Healthcare systems, financial institutions, manufacturers, and retailers all employ growing numbers of tech workers internally. The distinction between a “tech company” and a “company that employs a lot of tech workers” continues to blur, which means high-tech career opportunities are increasingly spread across industries.
What It Takes to Work in High Tech
The skills and credentials needed vary widely depending on the role. Software engineers and data scientists typically need proficiency in programming languages like Python, JavaScript, R, C, or C++. These are the core tools for building applications, analyzing data, and developing machine learning models. Many employers look for a bachelor’s degree in computer science, engineering, or a related field for these positions, though the weight placed on formal education has been shifting.
Not every high-tech job is a coding job. Product managers, for instance, may prioritize communication and strategic thinking over technical skills. Sales engineers need to understand the product deeply but spend their time working with customers. UX designers focus on how people interact with software rather than how the software is built. Technical writers, project managers, and business analysts all play critical roles in high-tech companies without writing a line of code.
Industry certifications have become an increasingly common path into tech roles, particularly in cybersecurity, cloud computing, and network administration. Certifications from organizations like CompTIA, AWS, Google, and Microsoft can help candidates demonstrate specific skills to employers. Some companies have dropped degree requirements for certain positions entirely, focusing instead on demonstrated ability through portfolios, certifications, or coding assessments.
What Makes a Company “High Tech”
Two characteristics consistently separate high-tech companies from the rest of the economy. The first is R&D intensity: these companies spend a large share of their revenue on research and development, creating new products or improving existing ones. A major software company might reinvest 15 to 25 percent of revenue into R&D, while a typical retailer or manufacturer might spend 1 to 3 percent.
The second is the concentration of STEM workers. A company can use plenty of technology without being high tech. A grocery chain runs sophisticated logistics software, but its workforce is overwhelmingly made up of retail and warehouse employees, not engineers. A semiconductor company, by contrast, fills its payroll with electrical engineers, physicists, and software developers. The workforce composition is what distinguishes a technology user from a technology creator.
This distinction matters for job seekers, investors, and policymakers. High-tech companies tend to offer higher wages, invest more in employee training, and cluster in regions with strong university systems. They also tend to be more sensitive to economic cycles tied to innovation spending and venture capital availability, which can make employment in the sector more volatile during downturns than in more stable industries like healthcare or utilities.
