Research cutoff: · Updated:The poverty line changes the question
A poverty rate is meaningful only alongside its threshold and method. The World Bank’s October 2026 brief reports different headcounts for its international poverty lines. These are purchasing-power-parity benchmarks: they compare purchasing power across economies rather than translating household resources at a market exchange rate. The brief’s welfare measure uses household expenditure per person with adjustments for differences in prices over time and place. It should not be described simply as reported cash income. s1
Inequality asks a different question: how unevenly resources are distributed. A poverty headcount can decline without a similarly large change in inequality. Neither measure alone describes wealth ownership, financial resilience, or every form of exclusion.
[s1]A setback followed by a partial recovery
The World Bank’s 2023 diagnostic describes worsening household welfare during the preceding decade, with poorer households benefiting less from expansions and suffering heavily during recessions. That finding concerns the distribution of economic change, rather than simply the national growth rate. Its historical estimates should be read within that publication’s methodology. s2
A subsequent Economic Monitor found falling poverty during the recovery covered by the annual observations below. It associated improvements with earnings and social transfers, including temporary transfer top-ups. Its decomposition is an analytical attribution of changes in measured welfare, not experimental proof that one policy caused the entire improvement. s3

Data, units and methodology
World Bank estimates from household expenditure data, with spatial and temporal price adjustments. The source uses Iranian reporting years spanning parts of two Gregorian years, labeled 2020/21 through 2022/23. The first integer identifies the source's starting Gregorian year; exact Gregorian boundaries are not assigned here. Values are percentages on a 0–100 scale, not currency amounts. This is a historical publication vintage, retained separately from newer 2021-PPP estimates.
| Reporting period | Population below $6.85 a day in 2017 PPP (percent of population) |
|---|---|
| 2020/21 | 29.29 estimated — World Bank survey-based estimate; threshold expressed in 2017 PPP.[s3] |
| 2021/22 | 24.82 estimated — World Bank survey-based estimate; threshold expressed in 2017 PPP.[s3] |
| 2022/23 | 21.92 estimated — World Bank survey-based estimate; threshold expressed in 2017 PPP.[s3] |
Only three directly tabulated comparable annual estimates were transcribed from this figure; the series is shorter than the preferred five observations.
The default 2012–2026 window is not fully covered.
Later releases use different PPP benchmarks and poverty thresholds; they are not appended to this historical series.
The dataset does not measure poverty depth, wealth inequality, or individual access to services.
National averages conceal differences
The October 2026 brief’s survey-based subgroup table shows higher poverty among rural residents than urban residents, and among children than older adults, at the same upper-middle-income benchmark. These are associations, not explanations of individual outcomes. Household composition, education, location, and employment conditions need to be examined together. s1
Regional disparities also appear in the earlier Economic Monitor, which highlights the southeast. Changes in the national average therefore cannot establish that every province or social group experienced equivalent progress. s3
[s1] [s3]Survey findings and the outlook are different evidence
The latest inspected brief combines survey-based results, a preliminary estimate for a later reporting period, and an outlook under conflict-related uncertainty. The outlook is not a completed survey of current living standards. s1
The most useful reading of Iran’s poverty evidence consequently preserves the original threshold, price basis, and reporting period. It also asks whether support protects purchasing power over time. A nominal payment and the goods it can buy are different quantities; the historical diagnostic identifies inflation-related erosion of transfers as an important limitation of social protection. s2

limitations
- The historical chart deliberately preserves its publication vintage and is not presented as the latest poverty series.
- The 2023 diagnostic and 2024 Economic Monitor use methodological conventions that prevent unqualified comparison of their headline estimates.
- The latest brief was inspected directly; search indexing for the same PDF URL included older material, so the PDF's visible October 2026 content was used.
- No independent causal evaluation of transfer effectiveness was inspected.
data gaps
- A complete comparable annual series for 2012–2026 was not retrieved.
- Recent survey estimates, preliminary later-period estimates, and projections were not combined into one chart.
- No verified current national poverty-line series or household wealth-distribution series was obtained.
