Residents will be selected at random from the national register, and men and women (15 years and older) will be invited to participate through a letter sent to their address. 

Should they wish to participate, they can either take the survey online by visiting the European health interview survey website (www.ehis.lu), or by requesting a paper questionnaire, in English, German, French or Portuguese.

The questionnaire touches on health status, healthcare utilisation, health determinants and socio-economic factors, but participants are not required to identify themselves by name, birthdate or address.

The aim of the survey, which takes place over the course of 2019, is to assess the health needs of citizens in order to better adapt to them in terms of national policies and evolution related to health and healthcare. 

Eurostat handles the nuts and bolts of the survey to help provide a baseline to compare data across the various EU member states.
