How this series is built
Share of the global income distribution. Neither an average nor a median.
World Inequality Database series sptincj992, percentile p90p100, from the published World (WO) file. This is WID's global interpersonal distribution of pre-tax national income among equal-split adults aged 20 and over — not a World Bank country Gini, and not WDI SI.DST.10TH.10, which has no World row. WID publishes shares as a 0–1 fraction; they are shown as percent. Sparse reconstructed World estimates before the annual series are omitted. Only years with a published World value are shown.
