1. 011980Iran-Iraq War beginsAssociation

   Eight-year war (1980-1988) imposes massive fiscal costs, disrupts oil exports, and entrenches a rationing/coupon system for basic goods.

   Why this link: Annual population growth more than doubled from its late-1970s trend (~3.0-3.4%/yr, 1977-79) to 5.25% (1981) and 5.29% (1982), coinciding with the war's onset and the Islamic Republic's well-documented wartime pronatalist stance (large families publicly encouraged; the Pahlavi-era family-planning program was dismantled after the revolution) -- consistent with the widely-cited Iranian 'baby boom' of the early-to-mid 1980s.

   Caveat: A jump from ~3% to over 5%/yr in two years is larger than pure fertility change alone plausibly explains. Substantial confounds: WDI's 'annual' growth-rate series for this period is partly a smoothing artifact of interpolation between Iran's bracketing 1976 and 1986 censuses, not a directly measured annual rate; and the recorded inflow of Afghan refugees after the December 1979 Soviet invasion of Afghanistan raises Iran's counted population without any underlying Iranian fertility change at all. Confidence capped at 2 given these unresolved confounds.

2. 021989First Post-War Five-Year Plan (Rafsanjani reconstruction)Association

   Rafsanjani government begins post-war economic liberalization and reconstruction planning after Khomeini's death (June 1989).

   Why this link: Population growth fell from 2.92%/yr (1989) to 1.98% (1992) to 0.36% (1993, a near-cliff) to 0.19% (1994) -- the leading edge of Iran's globally-cited 'fastest fertility transition in recorded history,' driven by the national family-planning program relaunched under the same post-Khomeini, post-war Rafsanjani government that began the First Post-War Plan in August 1989 (free/subsidized contraceptives, mandatory premarital family-planning classes, reversed cash-transfer incentives for large families).

   Caveat: The specific national family-planning program is not itself a discrete dated row in this project's timeline -- only the broader fiscal/reconstruction 'First Post-War Plan' event is present, so this links the population-growth collapse to the closest available dated policy anchor, not to the family-planning program by name. The sharp single-year 1993 cliff (1.98%->0.36%) is unusually abrupt for a gradual behavioral change and may partly reflect a WDI data/interpolation break around Iran's 1991/1996 census bracket rather than a pure one-year fertility collapse.

   Lag: gradual over 3-5 years, sharpest drop by 1993-94Source: Iran Data Portal (Syracuse University)
