ABSTRACT
    Cross-national
    studies on happiness have focused on differences in level of happiness. The
    focus of this paper is on spread in
    happiness in the nation, also called inequality in happiness. Inequality in
    happiness in nations can be measured by the size of the standard deviation of
    responses to survey questions about the overall appreciation of ones
    life-as-a-whole.
    This paper considers spread in
    happiness in 28 countries around 1980. Contrary to notions of a divided
    society none of these countries shows a bi-modal distribution of happiness. All
    distribution are uni-modal, but the distributions are not equally flat. There
    are considerable differences in size of the standard deviations. These
    differences are not a statistical artifact of variation in level of happiness
    and appear quite constant through time.
    
 
    Inequality
    in happiness appears to be greater in the socio-economically most unequal
    countries and smaller in politically democratic and economically developed
    nations. Contrary to expectation, inequality in happiness appears to be more
    closely linked to social equality among rich nations than among not-so-rich
    ones.
