1. 011963White Revolution launchedAssociation

   Shah's referendum approves a reform package including land redistribution, forestry nationalization, and profit-sharing for industrial workers.

   Why this link: Male tertiary gross enrollment led female enrollment by a wide, stable margin throughout the Pahlavi era and into the mid-1990s (5.7% vs 2.8% in 1978; 23.3% vs 14.4% in 1996). The gap then narrowed sharply: female enrollment briefly overtook male for the first time in 2008 (39.1% vs 33.4%) and held a narrow lead through 2012, before male enrollment regained and extended a lead from 2013-2020 (a 10-11 point gap at the 2015-2016 peak), and female enrollment edged back ahead again in 2021-2022 -- a genuinely oscillating, narrow-gap pattern since the mid-2000s that stands in sharp contrast to the wide, one-sided male-lead gap of the pre-1990s data. The White Revolution's 1963 extension of the franchise and other legal-rights measures to women is the earliest dated policy in this project's timeline plausibly connected to the multi-decade expansion of women's access to formal education that eventually produced this convergence.

   Caveat: This is a very long, indirect causal chain (45+ years from the cited event to the first crossover) with much more proximate drivers not captured as dated rows in this project's timeline -- particularly the 1982-founded Islamic Azad University network's massive expansion of geographically dispersed university seats, and the well-documented pattern of young Iranian women outperforming men on the national Konkur entrance exam. Confidence is kept low because the White Revolution is at best a distant enabling condition, not a proximate cause, and the pattern oscillates rather than representing a single permanent reversal.

2. 022018US withdraws from JCPOAAssociation

   President Trump announces US withdrawal from the JCPOA and reimposition of sanctions after 90/180-day wind-down periods (effective Aug 7 and Nov 5, 2018).

   Why this link: After peaking in 2015 (male 74.9%, female 66.2%), tertiary enrollment for BOTH genders declined through the sanctions-reimposition years to 2020-2021 lows (male 53.7-56.0%, female 54.9-55.3%) -- consistent with the economic contraction, currency collapse and household financial stress documented across many other charts in this database over the same window reducing families' ability to afford or justify continued university attendance.

   Caveat: Iran's own internationally-reported 2012-onward gender-based admission quotas restricting women's enrollment in certain fields at some universities is a plausible independent contributing factor to part of the female-specific trend, separate from the sanctions-driven economic channel affecting both genders; the two cannot be fully separated in this aggregate series, and neither the quota policy nor its later relaxations are dated rows in this project's timeline.
