This means that the real differences in life-satisfaction are probably somewhat greater than appears in these data.
Data from 2000 up to and including 2009. If the below mentioned questions had been used more than once in this era. the average score is used.

10-step numeral LifeSatisfaction

Cuba and Myanmar were involved in the 2006 Gallup WorldPoll. but are not included in this list since the sample was restricted to urban people.
