‘Valid’ empirical measurement of quality of life?

Results of empirical quality of life studies, undertaken hitherto, are subjectively influenced to a considerable extent by the researchers who try to measure the ‘quality of life’. In substantiation of this allegation it is shown on the basis of empirical data that the results are highly influenced, among others, (1) by the selection of indicators, (2) by the aggregation of indicators to one element, (3) by the weighting or non-weighting of the indicators, (4) by the indicator weigths given by different groups, (5) by employing different measurement techniques. Remarkable progress in empirical measurement could be made by the employment of objective indicators which are weighted by different groups (e.g., citizens, experts, decision makers, etc.). This approach can be called a ‘weighted objective indicator’ approach. In the second half of the article the proposal is made to measure infrastructure disparities both in physical and monetary terms. This permits a comprehensive assessment of the infrastructure's deficits and surplus on the level of indicators, subconcerns, and concerns.
