These datasets are the microdata which underpin the Office for National Statistics Foreign Direct Investment (FDI) statistics, which focuses on when a cross-border investment is made with the objective of establishing a lasting interest in the host economy. FDI is defined by influence relationships, where a direct investor (parent company) controls at least 10% of the voting power (ordinary shares) of the direct investment enterprise. The control can be measured in two directions: outward and inward. Outward refers to the direct investments of UK-resident companies in other countries, while inward refers to the direct investments in the UK from non-resident companies.
