Istanbul Hosts More Migrants Than Paris or Berlin — and Has Far Less Infrastructure to Show For It

Istanbul is home to the largest urban refugee population on Earth. Official figures from the Turkish Directorate General of Migration Management put the number of registered Syrians in the city at approximately 540,000, but municipal estimates used by Istanbul Metropolitan Municipality planners routinely run to three or four times that count when unregistered residents are factored in. Add Afghans, Iranians, sub-Saharan Africans, and Central Asians, and the city of 16 million is, by any credible measure, the most ethnically complicated metropolis west of Karachi.

The timing matters. Iran's political transition following the death of Supreme Leader Ali Khamenei is already pushing a new wave of educated, middle-class Iranians toward Istanbul, a city many use as a staging post for onward travel but where growing numbers are choosing to stay. Meanwhile, Europe is stiffening borders: Germany's new CDU-led government tightened its asylum threshold in March 2026, and Poland's prime minister this week flagged months of escalating security pressure from the east. Istanbul absorbs the overspill, largely without acknowledging that it is doing so.

What the City Actually Has — and What It Doesn't

The infrastructure is patchwork. In Bağcılar, a working-class district in the European half of the city where Arabic-language signage now outnumbers Turkish on several blocks of the main market street, a network of informal Arabic-Turkish tutoring cooperatives has emerged since 2019 largely without municipal funding. The Hayata Destek — Support to Life — NGO runs active caseload management for refugees out of offices in Sultangazi and coordinates with the İstanbul Valiliği, the provincial governor's office, on documentation renewals. But the organisation's own published figures show it handles roughly 12,000 active cases per quarter across a city with well over a million people in irregular or precarious legal status.

Fatih and Zeytinburnu, both on the European side, have become the de facto civic centres of Istanbul's Syrian community. The Fatih Municipality — controlled, unlike the metropolitan level, by the AKP — runs a limited Arabic-language social services window, but its scope is narrow: primarily health referrals and school enrollment for children. There is no city-wide language acquisition programme comparable to Berlin's Integrationskurse, which enroll nearly 200,000 participants annually and are federally funded at roughly €3,200 per person. Istanbul's equivalent, where it exists at all, is delivered by NGOs running on donor grants measured in thousands, not millions, of euros.

How Istanbul Compares — and Where It Punches Above Its Weight

The comparison with other high-migration cities is striking. Amsterdam's municipal integration budget for 2025 was €87 million for a city of 930,000. Paris runs the OFII — Office français de l'immigration et de l'intégration — with a national budget exceeding €400 million and mandatory language contracts for new arrivals. Istanbul, managing a migrant population that dwarfs both cities combined, has no dedicated metropolitan integration budget line that the IMM has made public, a gap that opposition CHP councillors raised in the city assembly as recently as May 2026.

Where Istanbul genuinely outperforms its European peers is in what researchers at Koç University's Migration Research Centre in Rumelifeneri describe as organic economic absorption. Syrian and Afghan entrepreneurs registered approximately 14,800 new businesses in Istanbul between January 2023 and December 2025, according to Istanbul Chamber of Commerce data. The textile workshops of Osmanbey and the food wholesale corridors of Bayrampaşa have integrated migrant labour and migrant capital with a speed and informality that no European city has matched — partly because no European city has been forced to try at this scale.

The practical reality for new arrivals in 2026 is this: register with the Directorate General of Migration Management office in Küçükçekmece within 30 days of arrival, enroll children in public school — legally required and largely enforced — and find Hayata Destek or one of a dozen smaller NGOs clustered near the Aksaray neighbourhood for legal and housing guidance. The city will not come looking for you with a structured programme. You will need to find what exists. In that specific sense, Istanbul is honest about what it is: a city of 16 million making room for more, mostly by stepping aside and watching people make room for themselves.
