STEM Degrees
China produces over 5 million STEM bachelor's graduates per year — more than the EU, US, and Japan combined. India produces ~2.5 million. STEM share of tertiary graduates varies from 15% (US) to 40%+ (Germany, Korea). Female participation in STEM has risen but plateaued at ~35-40% of STEM graduates in most advanced economies, with computer science notably worse.
Key insights
China's STEM output dwarfs everyone
China's annual STEM graduate output is approximately 5× the US and roughly 2× India. Engineering alone: ~1.4M Chinese graduates vs ~135k US. The volume reflects: China's larger overall tertiary enrollment, higher STEM share of degrees, and explicit government targeting since 2000. Quality varies — top Chinese universities produce world-class graduates, but tier-3 institutions vary widely. The volume effect on global research output and patent activity is already visible.
Female STEM share has plateaued
Across OECD, women earn 50-60% of all bachelor's degrees but only 35-40% of STEM degrees. Within STEM: 60-70% in biology and chemistry (often majority female), 15-25% in computer science and engineering (still heavily male). The composition matters — fastest-growing STEM fields (CS, AI/ML, engineering) are the most male-skewed. India and several Asian countries have higher female STEM share than the OECD.
CS and AI demand is reshaping degree mix
Computer science degrees as a share of STEM have surged since 2010 — at ~25-30% of US STEM bachelor's, up from 10% in 2005. AI/ML specializations have grown even faster within CS. Concerns about overproduction and labor market saturation have followed earlier engineering cycles. Other STEM fields (physics, mathematics, chemistry) have grown more slowly despite their importance to long-term scientific capacity.

Methodology & caveats
Defining STEM
STEM = science, technology, engineering, mathematics. Different sources include different fields: 'narrow STEM' (physical and life sciences, math, engineering, CS) vs 'broad STEM' (adding social sciences with quantitative focus, health professions, agriculture). Cross-country comparisons need explicit field-mapping. Most international statistics use ISCED Fields of Education categories.
Quality vs quantity
Headline graduate counts don't capture quality. China's top-tier institutions (C9 League) and India's IITs produce world-class graduates; tier-2/3 institutions vary widely. Citation rates, patent activity, research-paper quality are partial proxies. The 'STEM graduate gap' is real but may be smaller than headline numbers suggest after quality adjustment.
Where graduates go
Many STEM graduates don't pursue STEM careers. ~50% of US STEM bachelor's hold non-STEM jobs 10 years later. Brain drain affects developing-country STEM stocks — substantial fractions of Indian and Chinese STEM graduates emigrate. The contribution of STEM degrees to scientific and engineering capacity is mediated by where graduates work, not just where they were educated.
