This study attempts to close the gap between certain analytical methods and an effective use of stratified income distribution statistics. It summarizes available research and discusses the level of comparability and accuracy achieved by the data produced. Moreover, the piece reflects on tendencies in social welfare distribution.

One of the study's relevant conclusions is that in the post-1975 period one sees a change, probably structural, in Argentine income distribution patterns. Argentina, which in the early 1970s, among the countries of moderate income inequalities, had the highest income participation of its lowest strata, has fallen to the bottom end within this grouping, or among those with the least participation of the lowest income sectors.
