Information specifically relating to UK nationals enrolled at higher education institutions (HEIs) in other EU countries is not available.
Eurostat collects data primarily on the basis of the country in which students completed their secondary schooling. In absence of this, they collect data on the basis of the students’ usual or permanent residence prior to their higher education studies, or their citizenship. Eurostat data shows that approximately 13,000 students whose country of origin was the UK were enrolled in HEIs in EU countries in academic year 2013/14, and approximately 5,000 were studying first degrees.
Eurostat publishes these statistics on their website and they can be accessed using the web tool at the following link: http://appsso.eurostat.ec.europa.eu/nui/show.do?dataset=educ_uoe_mobs02&lang=en
