Like the broader metric of R&D intensity, the prominence of R&D value added in a state’s economic output has shifted within several states over the past decade. Does it matter? For sustaining a state’s innovation competitiveness, it may, and subsequently it is important to know for many state and regional TBED initiatives. Proximity to the conduct of R&D has been well documented in empirical research to support strong regional innovation economies. Subsequently many TBED policies are designed to increase and maintain R&D activity within those boundaries as well as ensure the localized spillover effects are maximized. Determining where R&D activity is thriving and the size of its value added to the state’s GDP, particularly manufacturing-related R&D, may help inform those policy decisions. SSTI explores the latest data on state R&D value added in this Useful Stats article.

Understanding the composition of local economies requires looking beyond broad statewide or national trends. County-level data reveals the unique mix, or lack thereof, of industries and businesses in each area. Policy makers, by identifying which sectors drive employment and business activity within a locality, can influence the impact and design of regional innovation strategies to reflect local realities and potential.  

The U.S. Bureau of Labor Statistics’ Quarterly Census of Employment and Wages (QCEW) allows examination of county-level employment and establishment counts across all private sectors at the 2-digit NAICS level. In this article, SSTI uses annualized private sector data for all provided 2-digit NAICS sectors at the county level for 2015 and 2024.
