Life satisfactionLife satisfaction is measured on an 11 point scale which ranges from 0 (“not satisfied at all”) to 10 (“fully satisfied”). For better understanding and interpretation and to facilitate analyses, which identify drivers for low and high satisfaction, answer categories were grouped into low, medium and high. As no theoretical or external criteria were available on an international basis, this classification was based on a 20:60:20 distribution at European level. That means having 20 % of answers in the lower part of the scale, 60 % in the middle and 20 % in the higher part, which leads to the definition of the following thresholds: 0-5 as “low”, 6-8 as “medium” and 9 and 10 as ”high”.
