Sources of Variation in Quality of Life in Romania

This paper capitalizes the results of a research undertaken on the quality of life in order to develop the general theoretical approach to the quality of life and to investigate the variation sources of the quality of life. If it wants to analyse the quality of life in absolute and relative term, then it can be used the indices method. This method measure the variation of the level and structure of the quality of life. If it wants the decomposition of the total variation of the quality of life on influence factors, then it can be used the chain substitution method or the separate influences method or the R. Struck method. The R. Struck is the most common method because uses the factor analyses. The aim of this analysis is to identify new variables which express synthetically the previous variables so that the total amount of information is only lost in a controlled manner.This context has emphasized the noticeable need for theoretical representations targeting the specific problems of calculating several indicators and assessing the quality of life. The emphasis regarding the use of a system of indicators has also moved from measurement-evaluation to the evolutionary-compared function. In this context, in the developed countries serious attention is being paid to the regional aspect of the problem.
