Abstract

This is a presentation on a new approach for additive index factor analysis. The novelty is, that for the decomposition of the resulting quantity of total growth into the respective sub-growths, the structural characteristics of the extensive factor is clearly outlined. This brings the schemes of the analysis closer to the reality and the factor sub-growths are presented in a much easier and simpler way with a much more transparent formal external entry. 
The problems concerning the decomposition of the total growth are discussed for both types of weights - basic and reported. The similarities and differences between both types of weighting are formulated as well as their interrelations. The derived theoretical analysis is supported with a real example elaborated on the grounds of the demographic practice in Bulgaria.
