Following a modified scheme of Max Weber's theoretical framework applied to the study of Social Stratification, was sought the conceptual basis for making an Index of Family Social Economic Status. After selecting the usual socio-economic variable - occupation, income and education - as indicators of family status, the respective weights were obtained by a statistical criterion (zero order correlation between each variable and the total score). According to its total score, each family is located in a certain social group, which represents a stratum in the rank system.
