The effect of deviations from trends in national income on mortality: the Danish and USA data revisited.

The issue of whether deviations from trends in national income predict mortality in Denmark is revisited. Earlier research has yielded mixed results. The hypothesis that increases, but not decreases, in inflation-adjusted per capita income are related to decreases in age standardized mortality is tested using methods responsive to criticisms of earlier work. Results support the hypothesis. The implications of the findings for research and policy are briefly discussed.
