Regional Analysis

Iran (Farsi)

• Population (speakers): ~93 million national population (2026 UN estimate); Farsi is the sole official language, first or second language for nearly all
• Christian %: ~1.8% Christian adherent, ~1.2% evangelical (Joshua Project)
• Primary Religious Affiliation: Twelver Shia Islam (state religion)
• Christian Population Profile: Mostly historic Armenian/Assyrian churches by adherent count, but a much-discussed, hard-to-measure underground movement of Muslim-background converts, estimated anywhere from ~100,000 to low millions depending on source (see prose below)
• Literacy Rate: ~85-88% adult literacy (World Bank/UNESCO-range estimate)
• Persecution Risk — Legal: Severe — no codified “apostasy” statute, but Article 167 of the constitution lets judges apply Sharia-derived rulings, including capital punishment, and converts are commonly charged with national-security offenses instead
• Persecution Risk — Social: Severe — family/community ostracism, job loss, social branding as a spy or foreign agent, intensified since Iran’s 2025 conflict with Israel
• Persecution Risk — Physical: Severe — documented raids, arrests, interrogation, executions in past decades (e.g. pastor Hossein Soodmand, 1990), and long-term imprisonment of convert leaders

Afghanistan (Dari)

• Population (speakers): ~45 million national population; Dari is co-official with Pashto and functions as inter-ethnic lingua franca; Dari-first speakers (Tajik, Hazara, Aimaq peoples) number in the low tens of millions
• Christian %: Statistically negligible per Joshua Project (rounds to 0.0%); absolute estimates from other sources range roughly 500 to 20,000 nationally
• Primary Religious Affiliation: Sunni Islam majority, with a significant Twelver Shia (Hazara) minority
• Christian Population Profile: Almost entirely hidden; no legally recognized Christian community since the Taliban’s 2021 return; believers meet in extreme secrecy or have fled
• Literacy Rate: ~37-43% adult literacy overall (World Bank-range estimate), with a sharp gender gap (women considerably lower)
• Persecution Risk — Legal: Severe — Taliban governance is explicitly Sharia-based; apostasy is treated as a capital offense with no legal protection for conversion or Christian worship
• Persecution Risk — Social: Severe — family and community response to a suspected conversion can be swift and can be triggered by minor signals such as not attending mosque
• Persecution Risk — Physical: Severe — Afghanistan ranked #1 on Open Doors’ World Watch List in 2022 immediately after the Taliban takeover and has remained in the “Extreme Persecution” tier (commonly ranked in the top 10-15) every year since

Tajikistan (Tajik, Cyrillic script)

• Population (speakers): ~11 million national population; Tajik ethnic group is roughly 80% of population (~9 million)
• Christian %: ~0.4-0.6% Christian adherent (Joshua Project and Wikipedia-cited figures both fall in this narrow range)
• Primary Religious Affiliation: Sunni Islam (officially secular state, heavy state regulation of religious practice)
• Christian Population Profile: Very small, largely non-Tajik historically (Russian Orthodox and other Soviet-era minorities); Tajik-background Christian conversion is rare and not well documented
• Literacy Rate: ~99.8% adult literacy (Soviet-era universal education legacy; World Bank-range estimate)
• Persecution Risk — Legal: Restrictive but different in kind — state control applies to all religion, including majority Islam (mosque attendance by minors banned, clergy and religious literature must be state-approved, informal beard/dress crackdowns tied to anti-extremism policy); not a codified individual apostasy-from-Islam law
• Persecution Risk — Social: Moderate — social cost of leaving Islam exists but is not reported as severe or systematic as in Iran or Afghanistan
• Persecution Risk — Physical: Low-to-moderate relative to Iran/Afghanistan — restriction operates mainly through state administrative control rather than documented violence against individual converts

Diaspora (Iranian, Afghan, and Tajik communities abroad — US, Germany, Sweden, UK, Canada, Australia, plus large Afghan refugee populations inside Iran and Pakistan)

• Population (speakers): Iranian diaspora conservatively estimated in the low millions; Afghan refugees in Iran alone have exceeded two million registered (UNHCR), with likely more unregistered
• Christian %: Higher than homeland populations in Western-diaspora communities specifically, reflecting both pre-existing Christian minorities who emigrated and converts who came to faith after leaving; no reliable single percentage exists
• Primary Religious Affiliation: Varies sharply by host country and generation
• Christian Population Profile: Diaspora Persian-speaking churches (especially Farsi-language congregations in the US and parts of Europe) are a real and growing part of this movement, often serving as a bridge for literature and discipleship material reaching believers back home
• Literacy Rate: Generally high, reflecting host-country norms
• Persecution Risk — Legal: Low in Western host countries; Afghan refugees inside Iran and Pakistan face compounding legal precarity (refugee status itself plus any conversion risk)
• Persecution Risk — Social: Low in Western host countries; still real risk for refugee populations inside Iran/Pakistan and for anyone whose conversion becomes known to family networks that reach back to the homeland
• Persecution Risk — Physical:

Christian population profile in detail

Iran’s Christian population by adherence (the Joshua Project ~1.8% figure) is dominated by historic ethnic communities, Armenian and Assyrian churches that predate Islam in the region and are constitutionally recognized (if still constrained) minorities distinct from the Persian-speaking Muslim-background convert movement this Language Package primarily serves. That convert movement is the subject of a genuinely wide range of size estimates precisely because it has to hide from the state that would estimate it: a 2015 academic study’s conservative figure near 100,000; NGO estimates from the 2000s onward commonly cited in the 300,000-500,000 range; higher-end ministry and advocacy estimates as high as 800,000 to 3 million; and a 2020 GAMAAN online survey (a large, self-selected panel of roughly 50,000 Iranians, so not a random sample, but one of the only attempts at direct measurement) in which 1.5% of respondents self-identified as Christian, a rate that would imply well over a million if extrapolated to the national population. None of these figures should be treated as precise; together they establish that the movement is large enough, and growing enough, to be widely and independently described, by Open Doors, Article 18, Middle East Concern, and scholars such as Shay Khatiri (Johns Hopkins University, whose 2018 estimate put the figure as high as half a million), as one of the fastest-growing evangelical movements in the world relative to population. Afghanistan’s Christian population is smaller in absolute terms and even harder to estimate, with figures from International Christian Concern (15,000-20,000), the US State Department (500-8,000), and USCIRF (10,000-12,000) all in circulation and none authoritative; the Taliban’s own public position is that no Christians remain in the country at all, which is itself part of the risk picture rather than a credible demographic claim.

Literacy context

Iran’s adult literacy rate, commonly placed in the mid-to-high 80s by World Bank and UNESCO-range estimates, supports broad printed and digital Bible-literature distribution in principle; the constraint is legal (distribution of Christian literature in Persian is illegal), not educational. Afghanistan’s much lower literacy rate, and its sharp gender gap, mean audio and oral-format material matters more there than in Iran, particularly for women. Tajikistan’s near-universal literacy (a Soviet-era legacy) is not currently load-bearing for this Language Package, since Tajik-script (Cyrillic) translation work is out of scope, as noted below.

Persecution risk narrative

Open Doors’ World Watch List, the most widely cited annual persecution index, has ranked Iran inside its top ten “Extreme Persecution” countries essentially every year for the past two decades; recent lists place it in roughly the 9th-10th position, with “Islamic oppression” and “dictatorial paranoia” cited as the primary drivers. Afghanistan’s ranking has moved more dramatically: it spiked to #1 on the 2022 World Watch List in the immediate aftermath of the Taliban’s August 2021 takeover, and while it has since settled to a somewhat lower position (recent lists place it roughly 10th-11th), it remains solidly inside the Extreme Persecution tier, and Freedom House rated its religious freedom at 1 out of 4 as of 2023. Both countries treat apostasy from Islam as, in effect, a capital matter, though Iran typically prosecutes converts under national-security statutes rather than an apostasy statute by name, while Taliban Afghanistan applies Sharia-derived reasoning directly. Iran’s risk has intensified further and specifically since its 2025 conflict with Israel, with the government publicly branding Christian converts as foreign spies or collaborators and Open Doors and partner organizations reporting dozens of arrests across multiple cities in the aftermath. Tajikistan is a materially different case: its restriction is a generalized, secular-authoritarian, Soviet-legacy pattern of state control applied to all religious practice, including the Sunni Muslim majority (banning minors from mosque attendance, requiring state approval of clergy and religious literature, periodic anti-beard and anti-hijab crackdowns tied to anti-extremism policy), rather than a specific theological apostasy-from-Islam danger aimed at individual converts. This is real and worth naming plainly, but it is a different kind of risk in degree and in kind from what Persian-speaking believers face in Iran or Dari-speaking believers face in Afghanistan, and it is part of why this Language Package, consistent with the existing precedent in this repository, treats Tajik-script (Cyrillic) translation work as out of scope: the core translation task here targets Perso-Arabic-script Iranian and Afghan Persian, where both the shared script and the shared, more acute persecution profile make a single Language Package coherent.
