The present publication presents time series which end before the United Kingdom’s withdrawal from the European Union on 1 February 2020. The EU aggregate presented here therefore refers to the EU including the UK. In future publications, as soon as the annual main aggregates presented for the EU extend for the first time to periods beyond the UK withdrawal (i.e. in March 2021 for the reference year 2020), the “European Union” aggregate will change to reflect the new EU country composition. Interested readers may refer to the Eurostat website for further information on Eurostat’s plans for disseminating EU aggregates and to the Eurostat database for the actual series.
