About two thirds of the Norwegian population exercise less than recommended
by public authorities. Traditional studies of exercise and social inequality using OLS-regression
give us information on the average person (conditioned mean value of a distribution),
but might ignore information useful for understanding the situation for those, as in
the Norwegian case, less physically active. In this article quantile regression – addressing
units at various quantiles, not only the mean – is used to study social inequality related to
physical exercise. Three types of exercise are studied – exercising locally, associational
sport, fi tness exercise – in light of social background variables. The crux of the analyses is
an understanding of how the dependence of various independent variables differs across
quantiles and that these results in several cases also differ from what OLS-regression tells
us. The data applied are Norwegian (ISSP 2007).
