Calculations are based on microdata from the European Quality of Life Survey (EQLS), coordinated by Eurofound. The survey aims to represent the population of all residents in a survey country aged 18 or older.
The data presented are a composite indicator based on 5 questions (Q51a, b, c, d and e) from the 2016 EQLS survey in the EQLS Integrated Data File, 2003-2016: Please indicate for each of the five statements which is closest to how you have been feeling over the last two weeks. [I have felt cheerful and in good spirits]; [I have felt calm and relaxed]; I have felt active and vigorous]; [I woke up feeling fresh and rested]; [My daily life has been filled with things that interest me]. Scale: 1 All of the time; to 6 At no time.
This composite indicator is only available for 2016, therefore no time series data are available.
The indicator is calculated as the mean score across the 5 questions out of all responses given by persons who answered the question (excluding those answering 'don't know' or refusing to answer). Answers to these questions are given on a 6-point scale, but have been rescaled onto a range from 0 (never experienced) to 100 (experienced all of the time).
The selection of relevant questions from the EQLS surveys to be included in the database was based on the following criteria:
