US income by ZIP code, from IRS SOI

This is a different object from the cross-country top-share series above: the IRS ZIP Code file groups filed returns inside each state and ZIP Code into six AGI stubs. The state totals below are the IRS state-total rows, summed across stubs 1-6 because this file has no agi_stub = 0 total row; the ZIP table appears only when a 5-digit ZIP is supplied.

California, 2022, carries 18,147,120 returns and $2.00T of AGI on the IRS state-total rows, across 1,475 ZIP rows plus $36.25B in the 99999 unallocated bucket. In that state total, stub 6 ($200,000 or more) holds 10.6% of returns and 52.0% of AGI.

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.
