Where Foreign Residents Actually Live in Turkey: Istanbul by the Numbers

Key Facts at a Glance

• Istanbul holds roughly half of all foreign residence permits in Turkey — more than five times as many as Antalya, the country's next-largest foreign population center.
• Turkmenistan, Azerbaijan, Syria, Iran, and Russia are currently the five largest nationalities among Turkey's foreign residence-permit holders.
• The same handful of Istanbul districts — Fatih, Esenyurt, and Başakşehir chief among them — have topped the city's foreign-population rankings for years.
• Since 2021, migration authorities have closed ten Istanbul districts, and dozens of individual neighborhoods elsewhere, to new foreign address registrations once the foreign share of a neighborhood's population passes 25%.
• The result is a foreign population that looks far less like the postcard “expat neighborhoods” of travel blogs and more like a set of dense, working-class districts shaped by decades of migration and community networks.

Search “best neighborhoods for expats in Istanbul” and you'll get a familiar shortlist: Kadıköy's cafés, Beşiktaş's Bosphorus views, Nişantaşı's boutiques, maybe Cihangir for the artsy crowd. None of that is wrong — plenty of foreign professionals do live in those neighborhoods. But it's a small, photogenic slice of a much bigger picture. Turkey's actual foreign resident population — the one tracked in residence-permit records rather than relocation blogs — is concentrated somewhere else almost entirely: in a cluster of dense districts most guidebooks never mention. We pulled the latest available figures from Turkey's migration and statistics authorities to see where foreign residents in Turkey really live, who they are, and why the government has spent the last several years trying, with limited success, to spread them out.

Istanbul's Share of the National Picture

As of the most recent count from the Presidency of Migration Management (Göç İdaresi Başkanlığı), Turkey had just over 1.15 million foreign nationals holding active residence permits. Istanbul alone accounted for more than 579,000 of them.

Table 1. Foreign residence-permit holders by province — Göç İdaresi Başkanlığı, 31 December 2025.

That single province holds roughly half of the country's entire foreign resident population — more than the next six provinces on the list combined, and over five times the total in Antalya, which sits a distant second. It's not a new pattern. Population researchers who have tracked the city's foreign residents over the years have long pointed to a rough “four in ten” rule: close to 40% of everyone with legal foreign residency in Turkey lives in Istanbul. TÜİK's own address-based population count backs that up almost exactly (599,118 of 1,570,543 nationally in the 2023 count, or about 38%) — and the newer permit-specific data above suggests the concentration has only deepened since.

Who's Actually Moving to Turkey

The mix has shifted over the past few years. Central Asian and Caucasus nationalities — Turkmenistan and Azerbaijan especially — have grown fastest, driven largely by education and family migration; Turkmenistan alone supplies more foreign students than any other single country. Russian arrivals picked up sharply in the mid-2020s. Meanwhile, Iraqi and Afghan nationals — who made up some of the largest resident communities through the 2010s — remain a substantial presence even though they no longer top the national list the way they once did; a large share of that population has settled long-term rather than moved on.

Syrians are a special case statistically: most who arrived fleeing the civil war are registered separately under temporary protection rather than as standard residence-permit holders, so the 79,455 figure above understates the real number of Syrian nationals living in Turkey by a wide margin.

The Districts Where Foreign Residents Actually Cluster

Zoom into Istanbul and the pattern sharpens further. A small number of districts — none of them on the “best neighborhoods for expats” lists — account for a disproportionate share of the city's foreign residents.

Fatih, the historic peninsula district that holds most of Istanbul's Ottoman-era landmarks, has topped or nearly topped this list for close to a decade. It's also home to major universities, the city's central administrative offices, and — not coincidentally — some of Istanbul's oldest and largest Syrian, Iraqi, and Central Asian communities, many of whom arrived well before the 2010s wave of Middle Eastern migration.

Esenyurt tells a different story. It's Istanbul's single most populous district by total population, and its foreign community has grown explosively — fast enough that it has swapped the #1 and #2 spot with Fatih more than once over the past several years. Much of that growth traces to Central Asian, Iranian, and Middle Eastern arrivals settling near the district's large informal manufacturing zones and a cluster of foreign consulates.

Başakşehir and Avcılar follow a broadly similar profile — newer, rapidly built-up districts on Istanbul's western edge with large Syrian, Iraqi, and Egyptian populations.

Zeytinburnu is the outlier worth pausing on. Its foreign population is smaller in absolute terms, but as a share of the district's own population it ranks among the highest in the city — and unlike its neighbors, that concentration isn't recent. Zeytinburnu has been a landing point for Central Asian and Chinese-Turkistani (Uyghur) migration since the 1950s, when the district's leather and textile industry gave newly arrived families steady, if informal, work. Academic researchers who have studied the district describe a community that today numbers in the thousands, with newer arrivals from the same countries still gravitating toward relatives and community networks already rooted there.

Elsewhere in the city, Beyoğlu's Tarlabaşı neighborhood and pockets of Şişli (notably Kurtuluş) have long served a similar function for African migrant communities — a first landing point close to informal-sector jobs in textiles, food service, and small retail, well before any of these residents show up in a “best neighborhoods” guide.

Why These Districts, and Not the Postcard Ones

The pattern isn't random, and it isn't really about nationality or culture in isolation — it's about cost, work, and networks, reinforcing each other.

Housing cost is the most obvious factor. The districts at the top of the list have historically had Istanbul's oldest, least renovated housing stock and correspondingly lower rents — though the arrival of large foreign populations has itself pushed those rents up over time, a source of friction with long-time residents that local officials have had to address.

Work is the second factor. Only a minority of Turkey's foreign residence-permit holders also hold a formal work permit; most support themselves informally, in sectors like textile manufacturing, construction, retail, food service, and domestic work — all industries concentrated in exactly these districts.

The third factor is simply community. Chain migration is powerful: a new arrival from Turkmenistan, Syria, or Nigeria is far more likely to move to a neighborhood where people from the same country, extended family, or hometown are already established — near the mosque, grocery store, or informal school that serves that community — than to pick a neighborhood at random.

A Government Trying to Reverse the Pattern

Turkish migration authorities have been actively working against this concentration for several years. Under a rule enforced by Göç İdaresi, once the foreign population of a neighborhood exceeds 25% of its total population, that neighborhood is closed to new foreign address registrations — existing residents can stay, and exceptions apply for newborns and family reunification, but new arrivals can no longer register a first address there.

As of the most recently published lists, ten entire Istanbul districts fall under this restriction: Fatih, Esenyurt, Avcılar, Bahçelievler, Başakşehir, Bağcılar, Esenler, Küçükçekmece, Sultangazi, and Zeytinburnu — precisely the districts that top the population tables above — along with dozens of individual neighborhoods in other parts of the city. Nationally, over a thousand neighborhoods across roughly 63 provinces are subject to the same restriction.

The practical effect is a slow redirection: new foreign residents who might once have settled in Fatih or Esenyurt are increasingly registering addresses in other Istanbul districts, or in provinces like Bursa and Mersin, which have both climbed the province rankings in recent years. Because these lists are reviewed periodically, anyone affected should confirm current status directly with Göç İdaresi before signing a lease.

What This Means If You're Considering Turkey Yourself

If you're weighing your own move — buying property, joining family already here, or relocating for work — the practical question these statistics raise for you is narrower than “which neighborhood has good coffee”: can you actually register an address there, and does your situation fit one of Turkey's residence permit categories in the first place? The restricted-district list above affects real applications, not just demographic trivia — it can determine where you're able to register at all.
