The BERD survey is carried out in all EU member states. 2021 data for the EU27 was not available at time of publication. The most recent data available from Eurostat is taken from the 2019-2020 survey and allows comparisons across the EU. R&D intensity for a country is defined as the R&D expenditure as a percentage of Gross Domestic Product (GDP).
In 2019 the R&D intensity rate for Ireland (0.91%) was below the EU27 average of 1.48%. Ireland ranked 13th in the EU27 in 2019, compared with a ranking of 12th in both 2017 and 2015.
Sweden had the highest R&D intensity rate in the EU27 in 2019 at 2.43%, while Latvia had the lowest at 0.17%.

Statistician's Comment
The Central Statistics Office (CSO) has today (04 May 2023) released Business Expenditure on Research and Development 2021-2022.
Commenting on the release, Devin Zibulsky, Statistician in the Business Statistics Division, said: “Business Expenditure on Research and Development measures the Research & Development (R&D) activities of enterprises in Ireland including expenditure, personnel, and sources of funding. Measuring R&D activity allows for viewing changes over time, international comparisons, and evaluating the social and economic impact of R&D.
In 2021, enterprises in Ireland reported a 19% increase in R&D expenditure to €3.88bn, compared with €3.26bn 2019. Labour costs accounted for the largest proportion of R&D expenditure, rising to €2.05bn in 2021 from €1.7bn in 2019. This reflected a growth in employment of R&D staff to 32,961 in 2021 from 27,755 in 2019. Large enterprises (with 250 or more persons engaged) accounted for 63% or €2.43bn of R&D expenditure in 2021, with Irish-owned enterprises accounting for 30% or €1.18bn of total R&D expenditure."
