As a technology and youth librarian, one of the most common questions I get from parents and students is: “Why does everyone push STEM so hard—and why are STEM jobs actually important?”
Usually, that question comes from frustration. Schools talk about science, technology, engineering, and math constantly, yet rarely explain what those jobs look like outside of a textbook or why a kid who doesn’t want to sit in a cubicle coding all day should care.
Why are STEM jobs important? STEM occupations keep critical everyday infrastructure running—from clean drinking water and stable power grids to hospital equipment and banking security—while paying more than double the median wage of non-STEM careers. With nearly 11 million STEM roles in the U.S. and over 800,000 new positions projected over the next decade, filling these jobs determines both household financial security and how well communities solve practical problems.
If you want a breakdown of specific career titles and salaries, check out our guide on what STEM jobs are and which ones pay the best. On this page, we will look at the hard numbers behind STEM employment and how these roles actually affect your daily life.

STEM vs. Non-STEM Jobs by the Numbers (2025–2035 BLS Data)
To understand why schools, libraries, and employers focus so heavily on STEM, look at the gap between STEM and non-STEM work in the latest U.S. Bureau of Labor Statistics (BLS) Employment Projections:
| Metric | STEM Occupations | Non-STEM Occupations | All U.S. Occupations |
| Total U.S. Jobs (2025) | 10,910,500 | 159,370,400 | 170,280,800 |
| Projected Jobs (2035) | 11,718,200 | 164,480,300 | 176,198,500 |
| Net New Jobs Added (2025–2035) | +807,700 | +5,109,900 | +5,917,600 |
| 10-Year Growth Rate (2025–2035) | 7.4% | 3.2% | 3.5% |
| Median Annual Wage | $106,360 | $49,050 | — |
| Approx. Median Hourly Pay | ~$51.13/hr | ~$23.58/hr | — |
Two numbers in that table stand out immediately:
-
STEM jobs are growing more than twice as fast as the rest of the labor market (7.4% vs. 3.2%).
-
The median STEM worker earns $57,310 more per year than the median non-STEM worker ($106,360 vs. $49,050).
1. They Keep Everyday Infrastructure From Breaking Down
When people hear “STEM,” they usually picture Silicon Valley software engineers or NASA rocket scientists. In reality, the most important STEM jobs are the ones you only notice when something goes wrong.
Every time you turn on a faucet, drive across a highway bridge, or flip a light switch during a summer heatwave, you are relying on applied science, engineering, and math:
| Everyday Need | The STEM Work Behind It | Example Roles |
| Clean Water & Roads | Testing water chemistry, designing storm drainage, and calculating bridge load limits | Civil Engineers, Environmental Technicians, Hydrologists |
| Power & Heating | Balancing electrical grid loads, troubleshooting high-efficiency HVAC systems, and integrating battery storage | Electrical Engineers, Power Plant Operators, HVAC Controls Technicians |
| Healthcare & Diagnostics | Calibrating MRI machines, analyzing blood labs, and formulating targeted medications | Biomedical Equipment Technicians, Clinical Lab Scientists, Biochemists |
| Food & Supply Chains | Preventing crop disease, testing soil nutrients, and optimizing freight routing | Agricultural Scientists, Industrial Engineers, Logistics Analysts |
| Digital Security | Stopping hospital ransomware attacks, securing banking networks, and protecting personal data | Information Security Analysts, Network Architects |
Without trained people stepping into these roles as older workers retire, basic public services get slower, more expensive, and less reliable.
2. They Drive Local Economies (Not Just Tech Hubs)
A common myth is that STEM careers only matter in major tech cities. While software and data roles make up the largest share of STEM employment, the economic ripple effect hits every local town.
When manufacturers, hospitals, civil engineering firms, and utilities can hire qualified technical talent locally:
-
Projects stay local: Cities and businesses don’t have to outsource engineering, testing, or IT infrastructure to outside contractors.
-
Higher local spending: Because the median STEM wage sits above $106,000 a year, those workers spend more on local housing, home repairs, restaurants, and small businesses.
-
Physical products get built: Every physical tool, vehicle, medical device, and building material requires materials scientists, CAD drafters, quality-control technicians, and industrial engineers before a single unit can be sold.
3. Many Essential STEM Jobs Are Skilled Trades (No 4-Year Degree Required)
One of the biggest reasons students tune out when adults talk about STEM is that they assume it means four to八 years of expensive university lectures. As we covered in our breakdown of what keeps students from pursuing a STEM degree, tuition costs and abstract math classes scare off plenty of capable kids.
However, a massive share of the U.S. STEM workforce—often called the “skilled technical workforce”—relies on two-year associate degrees, trade school certifications, or hands-on apprenticeships rather than a bachelor’s degree.
These roles use applied math, physics, and diagnostic technology every single day:
-
Industrial Machinery & Robotics Technicians: Programming and repairing automated factory equipment.
-
Electrical & Avionics Technicians: Testing circuitry, aircraft instruments, and power distribution panels.
-
CNC Machinists & CAD Drafters: Turning 3D engineering blueprints into precision metal and composite parts.
-
Telecommunications & Fiber Techs: Building the physical network infrastructure that keeps internet and emergency services online.
-
Environmental & Water Treatment Specialists: Monitoring municipal water supplies for contaminants and managing filtration systems.
For students who learn best by building, fixing, and troubleshooting with their hands, these technical trades offer strong pay without four years of college debt.
4. The Skills Gap Is About Problem-Solving, Not Just Job Titles
As we discussed in our post on why STEM education was created, the original push for STEM grew out of concern that U.S. students were falling behind in science and math proficiency.
Today, the challenge isn’t just filling jobs with “Engineer” or “Scientist” in the title. Even careers outside of traditional STEM—like construction management, modern auto repair, nursing, and finance—now require workers who can:
-
Read data and spot bad assumptions instead of guessing.
-
Troubleshoot complex systems step by step when a machine or process fails.
-
Adapt to new tools (including AI, diagnostic software, and automated equipment) without having to start their careers over from scratch.
Students who practice hands-on STEM activities early on don’t just memorize formulas—they learn how to test an idea, see why it failed, and fix it.
Related Questions About STEM Careers
How Much Do STEM Jobs Pay Compared to Non-STEM Jobs?
According to the latest Bureau of Labor Statistics data, the median annual wage for all STEM occupations is $106,360 (roughly $51.13 per hour), compared to $49,050 (roughly $23.58 per hour) for non-STEM occupations. That means the typical STEM role pays 116% more than the typical non-STEM job.
What Are the Biggest Benefits of Working in a STEM Field?
-
Above-average pay: Over 80% of STEM occupations pay above the national average for all jobs.
-
Stronger job security: Employment in STEM occupations is projected to grow 7.4% from 2025 to 2035, more than double the 3.2% growth rate projected for non-STEM jobs.
-
Multiple entry paths: While research science and engineering require four-year or advanced degrees, hundreds of thousands of technical, IT, and lab technician roles are open to graduates of two-year programs, trade schools, and certificate pathways.
-
Transferable problem-solving skills: Analytical and technical skills carry over across industries, making it much easier to pivot careers if one sector slows down.
