Fertility rate, total (births per woman)_

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: The total fertility rate, which had been declining steadily since the mid-1960s (7.2 in 1965 to 5.95 in 1975), reversed course and rose to 6.63 by 1980 and stayed above 6.4 through 1984 -- consistent with the Islamic Republic's early pronatalist stance (the Pahlavi-era family-planning program was dismantled after the revolution) and wartime social pressure to have large families, producing Iran's well-documented early-1980s 'baby boom' cohort.

   Caveat: Disentangling the war specifically from the broader 1979 revolutionary/religious shift in family policy is not possible from this series alone -- both point the same direction over the same years.

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: Fertility collapsed from 5.17 (1989) to 2.85 (1995) to 1.74 (2009) -- widely cited as among the fastest sustained fertility declines ever recorded for a country of Iran's size -- driven by the national family-planning program relaunched under the same post-war Rafsanjani government (free contraceptives, mandatory premarital family-planning classes, reversed incentives for large families).

   Caveat: None substantial -- this is one of the best-documented policy-to-demographic-outcome links in modern global fertility history.

3. 032018US 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 a government-encouraged pronatalist uptick lifted fertility from 1.74 (2009) to a local peak of 2.05 (2016), the rate resumed falling after sanctions reimposition, reaching 1.70 (2020) and continuing to 1.68 by 2024 -- consistent with the well-established cross-country pattern of economic hardship and currency instability depressing birth rates, layered on top of Iran's already-low structural fertility baseline.

   Caveat: Iran's own 2021 pronatalist 'Rejuvenation of the Population' law (restricting contraceptive access and abortion, incentivizing births) falls after this window and is not itself a dated row in this project's timeline, complicating a clean read of the most recent years; the 2010-2016 uptick itself is also not tied to a specific dated policy in this timeline (a genuine gap), so only the subsequent post-2018 renewed decline is attributed here.
