component that measures variations of groups of individuals (frequency) from t-1 to t, the original idea was to use it for education groups and verify whether education, in fact, influenced the movements or "mobility" of individuals in the markets income range, and how.On the other hand, a questionnaire prepared to qualitatively verify the importance of education in the hiring of applicants and promotion of those already occupied in the market was sent to a number of human resource professionals to be answered. Since the questionnaire was going to be sent out anyway to complement the evaluation of the role of education, it ended up strongly supporting the proposed objective, in the absence of quantitative information from IBGE[27].The questions included in the questionnaire were open so as to leave respondents free to include comments they deemed important and well founded. Twelve (12) professionals in the field of human resources were selected.Of the total, only 6 (six) agreed to answer the questionnaire and did not want to be named, either because they are directly linked to the companies, or are working in agencies that hire applicants as a service provided to other companies. The questionnaires were first sent out on June 23, 2013.It was possible to draw some conclusions and comments from the questionnaire responses that help understand what the education market is saying, as opposed to what academia insists on claiming. However, the evaluation of the questionnaire will be carried out after the evaluation of the income distributions.The questionnaire sent to the selected human resources professionals on June 23, 2013, is transcribed in Report handed in the Center for Public Policy Studies (NEPP).6.1.4- Analysis of income distributions of the Censuses (1960-2010)The following data refer to income distributions in Brazil in 1960, 1970, 1980, 2000 and 2010 All were obtained from the demographic censuses (IBGE). The first three came from Peliano (1992) and the last two from tables 1.7.8, 2000, People aged 10 years or older, employed during the reference week, with work income, value of monthly average nominal income... and 1.2.1, 2010, People aged 10 years or older and value of average nominal income ... by activity status in the reference week ... Incomes and frequencies of the economically active population (EAP) were obtained from all five distributions.There is statistical correspondence between the intervals of current income of the first three distributions (1960, 1970 and 1980) and the intervals of multiples of the minimum wage in the last two (2000 and 2010). There were no changes in the intervals of income brackets, only estimates of the respective average incomes by regressions.The evolution of the P inequality measure, through the trend of its magnitudes, matches that of the Gini coefficient taken as a reference, both by the estimates made in this study and the estimates of the Getulio Vargas Foundation (FGV) with information from the Censuses and the PNAD from the IPEA database.A third correspondence lies in the actual construction of the P inequality measure. Since this is an average of the calculations made for each average income and frequency of each income interval,
