R&D value added, or contribution to the economy, as a share of state gross domestic product (GDP) measures a state’s commitment to research and development. The latest figures show that the nation’s value added as a share of total GDP is 3.4 percent. Only eight states achieved or exceeded that share in 2023:

RankStateR&D Value Added as a Share of States’ GDP, 2023
1California5.9%
1Washington5.9%
3Massachusetts5.8%
4New Mexico5.5%
5Maryland4.4%
6Delaware3.9%
7District of Columbia3.6%
8Michigan3.4%

One common thread of the top three states is that each is home to a vibrant technology industry. The Bureau of Economic Analysis shows that more than half of all R&D value added in California, Washington, and Massachusetts was in two sectors: information and professional, scientific, and technical services.

The employment and wages of the men and women who work in R&D clearly demonstrate their economic impact. More than 3.2 million Americans worked in R&D in 2023, earning an average compensation exceeding $186,000. Employment in R&D topped 100,000 in 10 states:
