The growth and intensity of higher education R&D (HERD) expenditures varies considerably across metropolitan areas, a recent SSTI analysis of National Science Foundation data finds. New York ($4.3 billion), Boston ($3.2 billion), and Baltimore ($2.9 billion) had the highest overall levels of HERD expenditures in 2016. In that same year, Ithaca, New York (19.1 percent), State College, Pennsylvania (9.5 percent), and College Station, Texas (9.4 percent) had the highest levels of HERD intensity – measured as the share of HERD expenditures to gross metropolitan product. While overall HERD expenditures increased by nearly $7.5 billion nationwide from 2011 to 2016, more than half of this total (50.6 percent) went to the 10 metro areas with the most HERD expenditures in 2016.
