Gini coefficients: three survey measures side by side

Survey-based Gini coefficients from three sources, each on its own basis and shown with its year rather than blended. The OECD figure is disposable (post-tax, post-transfer) income, current definition; PIP is the World Bank survey Gini with its welfare concept (income or consumption); WIID is UNU-WIDER's latest High-quality observation, drawn from a compilation that spans welfare concepts, so each WIID figure carries the concept of the row it comes from. Bangladesh reads 0.309 on PIP consumption (2022) and 0.499 on its latest High-quality WIID row (2022), whose welfare concept is income (net/gross). Bangladesh is absent from the OECD, which covers members and a few key partners only; that gap is shown, not hidden.

UNU-WIDER WIID latest High-quality observation, shown with its welfare concept (native 0-100 scale shown here on 0-1). The WIID row is not filtered to a single welfare concept, equivalence scale or area coverage, and some selected rows are urban-only, so the column is a provenance check on the same economy rather than a like-for-like match to the OECD and PIP columns. WIID quality flags across the full base: 20,238 High of 26,161 observations, 200 economies.
