The STEM premium — how large is it, really?
Georgetown CEW 2024 data on bachelor’s median salaries by broad field:
| Major category | Starting (age 25–29) | Mid-career (age 35–45) | Lifetime earnings |
|---|---|---|---|
| Computer science / engineering | $75K–$82K | $135K–$150K | $3.5M–$4.1M |
| Business / finance | $58K–$66K | $95K–$120K | $2.5M–$3.0M |
| Biological sciences | $48K | $80K | $2.1M |
| Social sciences | $48K | $72K | $1.9M |
| Humanities | $46K | $72K | $1.9M |
| Fine arts / performing arts | $42K | $58K | $1.5M |
| Education | $43K | $58K | $1.5M |
The gap between CS/engineering and fine arts is roughly $2.5M over a 40-year career. That’s real money. But the gap between humanities and bio sciences or social sciences is smaller than most students assume — only about $200K lifetime.
Why “STEM” hides huge variance
STEM is not a monolith. Within STEM:
- Computer science, chemical engineering, petroleum: $75K+ median starting. Top of the market.
- Mechanical, electrical, industrial engineering: $70K median. Solid.
- Civil engineering: $62K. Lower than other engineering.
- Mathematics, statistics: $60K median — but variance is huge (quant finance vs. actuarial vs. teaching).
- Physics, chemistry bachelor’s-only: $50K median. Most need grad school for career traction.
- Biology bachelor’s-only: $48K median. Most students pursue grad school (med, PhD, PA) because the BA ceiling is low.
Meanwhile “liberal arts” hides its own variance:
- Economics: $60K median, competitive with some engineering.
- Philosophy: $50K median (surprisingly — law school pipeline).
- English / history: $45K median.
- Art history / comparative literature: $42K median.
- Early childhood education: $40K median, state pay scales.
The humanities + quant minor strategy
Pairing a humanities major with a minor in econ, math, or CS often captures 60–80% of the STEM salary premium while preserving the humanities major’s intrinsic appeal. An English + CS minor grad is a very employable product manager, technical writer, or UX researcher.Why the premium persists (and when it might shrink)
The STEM premium is driven by:
- Productivity signaling: STEM degrees credibly signal quantitative problem-solving ability employers can’t easily measure from a transcript.
- Scarcity: fewer students earn STEM degrees than market demand calls for, especially in specific sub-fields (semiconductor engineering, quantum computing, petroleum).
- Barrier to entry: STEM coursework has higher failure rates. Organic chemistry, thermodynamics, and proof-based math filter aggressively.
Factors that might shrink the premium in the next decade:
- AI automation of routine technical work — entry-level CS and junior engineering are most exposed.
- Increasing oversupply of CS bachelor’s — 2010s demand surge brought large cohorts that are now flooding entry-level market.
- Rising employer interest in “soft skills” (communication, leadership, adaptability) that humanities students demonstrate.
Major selection: a 4-filter framework
- Can you earn a 3.3+ GPA in it? A 2.8 in CS is worse than a 3.7 in English for career outcomes.
- Does the median earner live a life you want? Look at LinkedIn profiles of 10-year-out alumni of your target major.
- Does the field align with your long-term interests? Satisfaction at 40 matters more than peak salary at 30.
- Can you stack with minors/certs to capture higher-paying roles without switching majors?
