This table contains research and development (R&D) personnel statistics in large (TL2) regions. Indicators covered Number of R&D personnel is provided in both headcounts and full-time equivalent on R&D by sex, sector of performance (business enterprise, government, higher education, and private non-profit). Definition of regions Regions are subnational units below national boundaries. OECD countries have two regional levels: large regions (territorial level 2 or TL2) and small regions (territorial level 3 or TL3). TL3 regions are grouped into typologies based on shared characteristics. See the OECD Territorial Correspondence Table (xls) and the OECD Territorial grid (pdf).
