Idescat and the General Directorate for Language Policy of the Ministry of Culture of the Government of Catalonia are performing the Survey on Language Uses of the Population 2018. This survey, conducted every five years, is performed on a sample of the population of Catalonia aged 15 and above.

The internet survey can be completed starting in March 2018 to reduce costs and minimize any inconvenience for citizens. The survey will later be available in the telephone and face-to-face formats, if a citizen prefers either of them.

The participants in the sample have received a letter of introduction to the operation by post, with a username and password to permit access to the online survey.

In the event of any queries, please contact Idescat in the following ways:
