我们通过整合1970年至2000年间138个国家的个人收入分布来估计世界收入分布。国家分布是通过将国民账户人均国内生产总值与调查数据相结合来构建的，以锚平均值来确定离散度。报告了四个具体贫困线的贫困率和人口数。2000年，所有四条线路的费率都是1970年的三分之一到二分之一。2000年的贫困人口比1970年减少了2.5亿至5亿。我们估计了世界收入分配所隐含的八个收入不平等指数。所有这些报告都表明，1980年代和1990年代全球不平等现象有所减少。
We estimate the World Distribution of Income by integrating individual income distributions for 138 countries between 1970 and 2000. Country distributions are constructed by combining national accounts GDP per capita to anchor the mean with survey data to pin down the dispersion. Poverty rates and head counts are reported for four specific poverty lines. Rates in 2000 were between one-third and one-half of what they were in 1970 for all four lines. There were between 250 and 500 million fewer poor in 2000 than in 1970. We estimate eight indexes of income inequality implied by our world distribution of income. All of them show reductions in global inequality during the 1980s and 1990s.
