the level and evolution of income inequality among adults in Brazil between 2006 and 2012.
to calculate the level of inequality, its trend over the years and the share of income growth appropriated by different social groups.
We combined tax data from the Annual Personal Income Tax Returns (Declaração Anual de Ajuste do Imposto de Renda da Pessoa Física - DIRPF) and the Brazilian National Household Survey (Pesquisa Nacional por Amostra de Domicílios - PNAD) to construct a complete distribution of total income among adults in Brazil. We applied Pareto interpolations to income tax tabulations to arrive at the distribution within income groups. We tested the results, comparing the PNAD to the Brazilian Consumption and Expenditure Survey (Pesquisa de Orçamentos Familiares - POF) and to data from the Census Subsample Survey (Census.
We found evidence that income inequality in Brazil is higher than previously thought and that it remained stable between 2006 and 2012; in making these findings, we thus diverged from most studies on the dynamics of inequality in Brazil.. There was income growth, but the top incomes have appropriated most of this growth.
研究2006年至2012年间巴西成年人收入不平等的程度及演变情况。
计算不平等程度、多年来的趋势以及不同社会群体在收入增长中所占的份额。
我们将年度个人所得税申报表（Declaração Anual de Ajuste do Imposto de Renda da Pessoa Física - DIRPF）的税收数据与巴西全国住户调查（Pesquisa Nacional por Amostra de Domicílios - PNAD）相结合，以构建巴西成年人总收入的完整分布。我们对所得税表格应用帕累托插值法，得出各收入组内的分布情况。我们通过将PNAD与巴西消费与支出调查（Pesquisa de Orçamentos Familiares - POF）以及人口普查子样本调查（Census）的数据进行比较来检验结果。
我们发现有证据表明，巴西的收入不平等程度高于此前的认知，且在2006年至2012年间保持稳定；在得出这些结论时，我们与大多数关于巴西不平等动态的研究结果有所不同。收入有所增长，但高收入群体占据了大部分增长份额。
