Sources and data
OECD compiles national GERD returns on the Frascati Manual definitions so countries can be compared. The UK figure reflects ONS’s 2022 methodology change (wider business survey coverage), which raised UK estimates from about 1.7% to about 2.7–2.9% of GDP; pre-revision UK figures are not comparable. Latest year values may be provisional or OECD estimates. UK only: ONS revised business R&D upwards from its 2022 release (new survey sample frame), applied from 2018. OECD’s UK series is NOT consistently back-cast — values before 2018 (about 1.5–1.7% to 2013, about 2.3% for 2014–17) are on older bases and must not be joined to 2018+ values as a trend.
