Emphasis on STEM in culture  

Countries strong in STEM often prioritise technical education culturally, driving student motivation, exemplified by China, India, Korea, and Japan’s intensive schooling systems. In these nations, STEM education is often seen as a pathway to social mobility and national development, leading to high enrolment in engineering and science disciplines.

While this cultural emphasis can create academic pressure, it also generates a large base of STEM-capable graduates who contribute significantly to national innovation and global tech ecosystems. 

Conversely, nations lacking this cultural emphasis on STEM may experience lower participation rates in technical fields. To remain competitive, such countries are increasingly introducing measures to boost interest, such as curriculum reforms, STEM outreach programs, and incentives for underrepresented groups. 

In summary, East Asia and parts of Europe and North America produce the most well-prepared STEM students. Their high test scores (e.g., China’s PISA 2018 average of 578.7, Singapore’s 556.3, and Japan’s 520.0), along with consistent success in international competitions like the Science and Math Olympiads, reflect robust pipelines for future engineers, researchers, and innovators. 

STEM workforce and graduate volume 

China leads the world in STEM talent, producing approximately 3.57 million STEM graduates annually, which is about 40% of its university degrees. This immense output, projected to include over 77,000 STEM PhDs by 2025, underpins China's rapid tech growth. Although training quality varies, the top tier of graduates competes globally. 

India follows with around 2.55 million STEM graduates per year. Engineering and IT disciplines dominate, fuelling India's significant presence in global tech sectors and supplying talent worldwide. Projections suggest India could surpass China in annual graduates by 2030, though improving average educational quality remains a challenge. 

United States produces about 800,000 STEM graduates yearly, a modest figure compared to China and India. However, the U.S. excels at attracting international students and skilled immigrants, strengthening its workforce. U.S. STEM education emphasises creativity and interdisciplinary skills, and its workforce is prominent in advanced research fields. 

Other Countries: 

• Russia: ~520,000 STEM graduates per year, with well-regarded math and science training but facing brain drain. 
• Japan: ~550,000 per year, though numbers are plateauing amid a shrinking population; efforts are underway to attract foreign talent.
