In this paper we have chosen to analyze the methodological aspects and some interpretations, divulged by the Brazilian Institute of Geography and Statistics, proceeding from indicators obtained on two topics, surveyed by that institute. Our objective, therefore, was to evaluate methodologies and definitions employed by the 2010 Census in data collection about stepfamilies, as well as the methodological option and meanings used for seizure of bullying in the PeNSE research, 2009. Since the results of the investigations undertaken by the Institute are used to plot the course of public policies in Brazil, we consider the procedures employed should be in line with current theoretical discussions on the respective themes, which has not been evidenced in our analysis.
