The Danish Health Act which came into force on January 1, 2007 demands that the municipalities in Denmark are responsible for preventative sanitary measures and health promotion of which the levelling of the social inequality in health has become an eminent goal in many municipalities. In the light of this Act, earlier studies of social inequality in health are reviewed for the purpose of finding a quantitative measurement usable for the municipalities when preventative projects are being evaluated. This project paper is an attempt to answer these two questions: 1) Which measurements and methods of measurement are suitable for the description of the level of inequality in health? and 2) Which of these measurements and methods of measurement are suitable for the evaluation of the short-term efforts to levelling the inequality in health? The first part of the project paper reviews earlier publicized works on social inequality in health. Many of the studies do not measure inequality in health quantitatively, which is why there is no representation of the size of inequality or the extent of it. Also, the studies that measure the extent of the inequality use measurements that relate to “mortality”, which means the aim becomes long-termed and in substantial in connection to the evaluation of projects with children as the target group for instance. The first part of the project concludes that the healtheconomic methods, which measure “health” composed with a social indicator and which mark accumulative values for these elements into a Lorenz-diagram, are very useful in the work with short-termed projects on social inequality in health. The second part of the project paper attempts to utilize the healtheconomic method for measurement of social inequality in health. For this part of the project, the data is provided by North Denmark Region. The data includes self-assessed health and income. The method isapplied with these data in order to determine whether or not the method is serviceable for municipalities in the attempt to measure if a levelling has occurred in the inequality in health. This test finds the method very useful, but also emphasizes a need for supplements to the method with more qualitative measurements as a result of the complexity of the area. The empirical examination also concludes that the available data and the method of approach are very determinative for the outcome of the analyses.
