An earlier study, based on data from Western countries, concluded that
an international standard for life satisfaction could be stated as 75
+/- 2.5 percentage of the measurement scale maximum score. This study
presents a similar analysis based on data from countries representing
all major geographic regions. It is reported that these data yield a
more inclusive standard of 70 +/- 5 percentage of scale maximum. While
the major correlates of life satisfaction are found to be individuali
sm and national wealth, the life satisfaction levels of some countries
are distinctly anomalous in this regard. It is concluded that the nar
row range of population data suggest that life satisfaction is held un
der homeostatic control. The anomalous levels of life satisfaction rep
orted by some countries indicate caution in the interpretation of life
satisfaction data as implying some desirable population state.
