Mortality Studies in Unskilled and Semi-Skilled Workers in Denmark: A Comparative Analysis

Results from two Danish studies on mortality among male unskilled and semi-skilled workers are compared. The first study is based on union data, the second study on census data. Apparently conflicting results are found to be identical after making adjustment for differences in the study populations and standard populations. The male unskilled and semi-skilled workers have an excess mortality in the younger age groups which decreases with increasing age.
