本文提出了国际财富指数（IWI），这是第一个基于家庭物质福利或经济状况的可比资产指数，可用于所有低收入和中等收入国家。IWI类似于人口与健康调查和儿基会多指标类集调查中广泛使用的财富指数，但增加了跨地点和时间的可比性。IWI基于来自97个发展中国家210万户家庭的数据。通过IWI，我们为评估和比较发展中国家所有地区的家庭、社会群体和社会状况提供了一个稳定和可理解的标准。一个家庭在IWI上的排名表明了这个家庭拥有一系列基本资产的程度，这些资产受到全球人民的高度重视。IWI经过了彻底的测试，是一个稳定的指数，几乎不依赖于特定项目的纳入，也不依赖于特定地区或时间段的数据。国家IWI值与人类发展、预期寿命和国民收入高度相关，基于IWI的贫困指标与贫困人口比率高度相关。
This paper presents the International Wealth Index (IWI), the first comparable asset based index of household's material well-being, or economic status, that can be used for all low and middle income countries. IWI is similar to the widely used wealth indices included in the Demographic and Health Surveys and UNICEF MICS surveys, but adds the property of comparability across place and time. IWI is based on data from 2.1 million households in 97 developing countries. With IWI we provide a stable and understandable yardstick for evaluating and comparing the situation of households, social groups and societies among all regions of the developing world. A household's ranking on IWI indicates to what extent the household possesses a basic set of assets, valued highly by people across the globe. IWI is tested thoroughly and turns out to be a stable index that hardly depends on the inclusion of specific items or on data for specific regions or time periods. National IWI values are highly correlated with human development, life expectancy, and national income, and IWI-based poverty measures with poverty headcount ratios.
