Launching on the 2012 European Day of Languages, languageknowledge.eu is a new website that visualizes language knowledge in Europe based on the latest European Commission survey data, published this summer in the “Europeans and their languages” Eurobarometer.
The interactive website allows visitors to find out which languages are most widely known in Europe, by country, age groups, and see the split between native speakers and people who learned the language later in life. Visitors can also pick any language to see in which countries that language is most popular.
