Turbulent research landscape imperils US brain gain and ultimately American prosperity

Despite representing only 4% of the world's population, the United States accounts for over half of science Nobel Prizes awarded since 2000, hosts seven of The Times Higher Education Top 10 science universities, and incubates firms such as Alphabet (Google), Meta and Pfizer that turn federally funded discoveries into billion-dollar markets.

The domestic STEM talent pool alone cannot sustain this research output. The U.S. is reliant on a steady and strong influx of foreign scientists - a brain gain. In 2021, foreign-born people constituted 43% of doctorate-level scientists and engineers in the U.S. They make up a significant share of America's elite researchers: Since 2000, 37 of the 104 U.S. Nobel laureates in the hard sciences, more than a third, were born outside the country.

China, the U.S.'s largest competitor in science, technology, engineering and math endeavors, has a population that is 4.1 times larger than that of the U.S. and so has a larger pool of homegrown talent. Each year, three times as many Chinese citizens (77,000) are awarded STEM Ph.D.s as American citizens (23,000).

To remain preeminent, the U.S. will need to keep attracting exceptional foreign graduate students, budding entrepreneurs and established scientific leaders.
