Net Wealth Share, Top 10%
FAO publishes this commodity's food-balance elements in two domains with different methodologies (historic 1961-2013 vs current 2010-2023); they disagree materially where they overlap, so both are kept as separate labelled series rather than spliced.

··2006First Justice Shares distributedCorrelationExpected causation
Under the Article 44 privatization framework, the government begins distributing subsidized 'Justice Shares' (Saham-e Edalat) in state-owned enterprises to low-income households, war veterans' families and Basij members; by December 2006 roughly 4.6 million Iranians have received shares worth about $2.5bn (around $550/person), with a decade-long restriction on trading them.
Why this link: The scheme was explicitly designed to broaden asset ownership among low-income households, a policy channel intended to reduce wealth concentration at the top.
Caveat: Studies of the scheme's actual distributional impact are mixed, with many shares eventually concentrating in fewer hands or losing value.

Laws related to this measure. Correlation = how closely this law tracks this measure's story. Expected causation = how strongly we would expect it to have moved the line. Neither is a claim of proof.
1960CorrelationExpected causationLand Reform Act (1960)
Passed in 1960, this is the first Iranian Land Reform Act, defining farmers, tenant farmers and landowners and setting a legal framework, later replaced by a stronger 1962 law, for redistributing agricultural land from large landlords to the peasants who worked it.
Why this link: By breaking up large landed estates and transferring ownership to smallholders, the law reduced the concentration of rural wealth held by a small landlord class, a structural shift relevant to Iran's long-run inequality trajectory.
Caveat: Long-run inequality series are dominated by oil-rent distribution, urbanization, and post-1979 policy shifts, so the land reform's specific imprint on top income/wealth shares decades later cannot be cleanly separated from these later forces.
1962CorrelationExpected causationIn Implementation of Note 3 of Article 2 of the Land Reform Act
Issued by the Council of Ministers in 1341 (1962) to implement Note 3 of Article 2 of the Land Reform Act, this decree sets the procedure for surveying, partitioning, and allocating the government's share of undivided (jointly-owned) agricultural estates subject to land reform, including a dispute-resolution commission for objecting landowners.
Why this link: By governing how state-owned shares of jointly-held land were divided and transferred, this decree is a direct operational piece of Iran's land redistribution, the single largest change to landownership and farm structure in modern Iranian history, with a real channel into agricultural land-use, production and land-wealth-concentration statistics.
Caveat: This decree covers only the technical partition of state shares in jointly-owned estates, a subset of the broader multi-stage land reform; its own measurable effect on national agricultural output or wealth-concentration series is entangled with the reform's other, larger phases and with weather-driven output swings.
1967CorrelationExpected causationAct on the Establishment of the Ministry of Land Reform and Rural Cooperation
Passed in 1967, this law creates the Ministry of Land Reform and Rural Cooperation to implement land reform legislation, promote rural cooperative companies, and organize farm corporations, transferring the Land Reform Organization and Central Rural Cooperation Organization to it from the Ministry of Agriculture.
Why this link: Land redistribution from large landowners to peasant cultivators was intended to reduce rural land concentration and, through it, income and wealth inequality.
Caveat: Inequality data for this era is sparse and partly reconstructed, and later oil-boom income concentration and rapid urbanization likely dominate any inequality trend, making the land-reform effect hard to isolate.
2005CorrelationExpected causationExecutive Bylaw on Expanding Ownership and Increasing the Wealth of Iranian Households
Issued in 2005, this bylaw sets the procedure for distributing shares of state-owned enterprises earmarked for privatization to lower-income Iranian households, through intermediary investment companies that hold the shares and allocate them to eligible individuals by income decile, a precursor to the later Justice Shares program.
Why this link: This bylaw operationalizes Iran's 'Justice Shares' program, distributing state-owned enterprise shares to tens of millions of low-income households via intermediary holding companies, a deliberate national wealth-redistribution instrument.
Caveat: Wealth-share estimates are model-based, and Iran's overall wealth concentration is driven by far larger forces (oil rents, inflation, sanctions) than this single distributive program; distributed shares also had limited liquidity and disputed real value to beneficiaries.
Lag: Multi-year rollout from 2006 onward, with share transfers continuing for a decade.2006CorrelationExpected causationExecutive Bylaw on Increasing Household Wealth and Expanding the Cooperative Sector's Share Through the Distribution of Justice Shares
Issued in 2006, this bylaw sets up the central and provincial headquarters that plan, coordinate and oversee Iran's Justice Shares privatization program, defining eligible recipients as households in the two lowest income deciles and the chain of intermediary cooperative and investment companies that distribute the shares.
Why this link: This bylaw raised the cooperative sector's share in the distribution of Justice Shares (state-enterprise equity handed to low-income households), a direct redistribution instrument aimed at household wealth.
Caveat: Justice Shares carried negligible tradable value and delayed dividends for most of their history, so this measure's contribution to measured wealth-share series cannot be separated from broader distributional trends.
Lag: multi-year (distribution occurred in tranches)2008CorrelationExpected causationDirective on the Process of Identifying and Finalizing the Confirmation of Beneficiaries of the Justice Shares Transfer Plan for Journalists
This directive establishes the process for identifying and confirming journalists eligible for the Justice Shares transfer plan.
Why this link: This bylaw implements a narrow slice of Iran's Justice Shares (privatization) program, verifying journalists' eligibility for allocated state-enterprise shares, part of a wider policy intended to broaden public ownership of formerly state-owned assets.
Caveat: This is a narrow procedural directive for one occupational group within the much larger nationwide Justice Shares program; its own effect on wealth or income distribution is negligible and cannot be distinguished from the broader programme's impact, which itself is only weakly reflected in available inequality series.
2009CorrelationExpected causationBylaw on the Installment System for Transfer and the Method of Collecting the Price of Transferable Rights
This bylaw establishes the installment payment system and collection method for the price of transferable rights.
Why this link: By spreading payment for state land and assets over installments, the bylaw broadened the pool of households able to acquire such assets, a mechanism relevant to household wealth accumulation.
Caveat: Wealth-share series are shaped far more by asset-price inflation, currency depreciation, and informal-sector dynamics than by this one installment mechanism.

This ruling by the Administrative Justice Court's General Board concerns the Director General of Justice Shares Affairs at the Privatization Organization.
Why this link: Justice Shares administration bears on the household wealth these shares represent for millions of low-income recipients.
Caveat: A jurisdictional ruling about who administers the shares does not itself move measured wealth-share statistics.
Lag: no measurable lag
