Change in output in EU manufacturing by technology level

Volume of industrial production is one of the indices in the list of Principal
European Economic Indicators, which measures changes in the volume of
industrial output. Details of the methodology used for its calculation can be
found on Eurostat’s site.
The percentage change in the volume index of production in manufacturing
is compared to the same period in the previous year. (Data is adjusted by
working days.) For the EU-28, the change in volume of manufactured production
is also presented, grouped by level of technological sophistication,
with the four groups defined on the basis of the R&D expenditures in relation
to value added. Exemples of the manufactured goods included in each
group can be found on Eurostat’s site.
