Wealth

We provide wealth related indicators for countries and subnational regions within these countries. The heart of the Wealth indicators is the International Wealth Index (IWI), which is the first comparable asset-based wealth index covering the complete developing world. In addition we provide asset-specific indicators, poverty and inequality measures.

Computing IWI

To compute the IWI value of a household, information is needed on twelve assets. These assets include seven consumer durables, access to two public services, and three housing characteristics.

Play with IWI online

We provide an online form to quickly compute the IWI index for a household. This is done by filling out a form with questions pertaining to each of the indicators IWI accounts for.

Map visualisations

Our world maps allow the visualization of the Wealth indicators across all lower- and middle-income countries at a given point in time. This is a key instrument in visualizing regional differences within and across countries.

Data tables

We provide easy to navigate data tables displaying the wealth, poverty and inequality indicators in a grid-like format of rows and columns. Information is available along three dimensions: (i) country, (ii) time, and (iii) choice of indicator(s).
