Russian-Occupied Ukrainian Territories 2026: Geography, Population, and Governance
1. Overview: Scale and Scope of Occupation
Russia's occupation of Ukrainian territory — the largest forcible land acquisition in Europe since World War II — spans five distinct geographic regions and encompasses approximately 107,000–112,000 km², or approximately 18–19% of Ukraine's internationally recognized territory. The occupation takes two forms: a decade-long settled occupation of Crimea (since 2014) and an active-conflict occupation of eastern and southern Ukrainian regions seized during the 2022 full-scale invasion.
The territorial situation has been characterized by significant stability since late 2022, with neither side able to make decisive offensive progress. Russia declared the formal "annexation" of four Ukrainian oblasts (Donetsk, Luhansk, Zaporizhzhia, and Kherson) in September 2022, even though it did not fully control any of these four regions at the time of the annexation declaration — a legally meaningless but politically significant act. These declarations have been rejected by the UN General Assembly and the vast majority of states.

3. Crimea: Decade-Long Occupation (2014–2026)
Crimea represents Russia's most consolidated occupation — twelve years of administrative integration that has substantially deeper roots than the 2022-seized territories:
- Annexed in March 2014 following a contested referendum conducted under Russian military occupation; virtually all Western governments, international organizations, and most non-Western states refused recognition
- Population (~2M) includes a Russian-speaker majority (60–65%), Ukrainians (~24%), and the indigenous Crimean Tatar minority (~12–15%); Crimean Tatars have faced particularly severe repression including property seizures, mosque closures, and criminal prosecutions of community leaders under terrorism statutes
- Military significance: Sevastopol is home to what was the Russian Black Sea Fleet HQ; Ukrainian long-range strike and drone campaigns (2023–2024) significantly damaged Black Sea Fleet capability — including the sinking or disabling of over a dozen major surface vessels; the fleet largely relocated to Novorossiysk by 2024
- Kerch Bridge (Crimea Bridge): bombed by Ukraine in October 2022 and again in July 2023; partially reconstructed; serves as primary land link and symbol of the occupation; remains a high-profile Ukrainian strike target
- Economic trajectory: significant Russian investment in Crimea infrastructure (road, rail, bridge) has not translated into economic prosperity for most residents; international sanctions and disconnection from mainland Ukrainian economic networks have impoverished the peninsula relative to both pre-2014 levels and mainland Russia equivalents
4. Luhansk Oblast: Near-Total Occupation
Luhansk Oblast is the most thoroughly occupied Ukrainian region (excluding Crimea), with approximately 97% of the oblast under Russian control after the fall of Lysychansk in July 2022:
- The pre-war "Luhansk People's Republic" (LPR), established after 2014, controlled roughly 1/3 of Luhansk Oblast; the 2022 full-scale invasion completed Russia's conquest of the remaining Ukrainian-controlled areas through the summer campaign culminating in Lysychansk
- The oblast is now fully integrated into Russian administrative structures; it is governed as a Russian federal subject with an appointed "governor"
- Population: pre-war ~2.3M (of whom ~1.6M were in then-Ukrainian-controlled areas); massive displacement has reduced the remaining population to an estimated 1.0–1.4M; diaspora spread across Ukraine proper, European Union, and Russia
- The front line in Luhansk Oblast is minimal (only very small portions near Svatove-Kreminna axis remain contested); it is primarily a rear-area logistics and administration province for Russian forces operating in Donetsk Oblast
5. Donetsk Oblast: Active Front, Partial Occupation
Donetsk Oblast is the most strategically contested region — home to the most intense ongoing fighting and the highest daily casualty rates of any sector:
- Pre-war population: ~4.1M (the most populous oblast in Ukraine); approximately 2.5–2.8M of this population lived in what is now occupied areas including Donetsk city (~900,000 pre-war inhabitants) and Mariupol (~450,000 pre-war)
- The major population centers under occupation include Donetsk city (controlled by the "Donetsk People's Republic" since 2014), Mariupol (besieged and captured Spring 2022), Horlivka, and Makiivka
- Mariupol has particular symbolic and strategic significance: the Azovstal steelworks siege (April–May 2022) ending in the surrender of the Azov Battalion was the war's most famous siege; Russia has invested in Mariupol reconstruction as a showcase; the city's pre-war Ukrainian character has been substantially Russified
- Active battle areas (spring 2026): the Pokrovsk direction, Chasiv Yar (largely Russian-controlled), Toretsk sector, and the broader Donetsk-Dnipropetrovsk boundary remains the primary active front
6. Zaporizhzhia Oblast: Strategic and Industrial Value
Zaporizhzhia Oblast's occupation is strategic for two primary reasons: it forms the land bridge connecting Russia to Crimea, and it contains the Zaporizhzhia Nuclear Power Plant (ZNPP), Europe's largest nuclear facility:
- The "land bridge" from Russia through Donetsk–Zaporizhzhia–Kherson to Crimea was one of Russia's primary strategic objectives in 2022; it has been secured and represents Russia's most significant territorial gain of the war
- Key occupied cities: Melitopol (~150,000 pre-war; major rail and logistics hub for the land bridge), Berdyansk (port city on the Sea of Azov), Enerhodar (power plant operations city)
- ZNPP occupation: the Zaporizhzhia Nuclear Power Plant at Enerhodar has been under Russian military control since March 2022; it has been in cold shutdown since September 2022; IAEA monitoring team is present; the plant's occupation and associated safety incidents (power cuts to cooling systems, perimeter shelling, mine placement concerns) have been repeatedly cited as a major nuclear safety risk (see: Zaporizhzhia Front Analysis)
- Approximately 30–35% of Zaporizhzhia Oblast (including the city of Zaporizhzhia itself, population ~750,000) remains under Ukrainian control; Zaporizhzhia city has been heavily shelled throughout the war
7. Kherson Oblast: River Divided
Kherson Oblast is the only region where Ukraine liberated a major population center — the right-bank liberation of Kherson city in November 2022 created a divided oblast bisected by the Dnipro river:
- Right bank (Kherson city and surroundings): liberated November 2022; Ukrainian-controlled; subject to ongoing heavy Russian artillery, missile, and drone bombardment from across the river; Kherson city has remained under near-constant fire throughout 2023–2026
- Left bank (occupied): approximately 50–55% of the oblast's area; including Nova Kakhovka (site of the June 2023 dam explosion that flooded the lower Dnipro and destroyed downstream agricultural infrastructure)
- Kakhovka Dam breach (June 2023): the destruction of the Kakhovka Dam — attributed by Ukraine and most Western analysts to Russian demolition; Russia blamed Ukraine — caused catastrophic flooding across the lower Dnipro affecting approximately 80 downstream settlement, displacing up to 50,000 people and destroying vast areas of farmland and infrastructure; the environmental damage persists into 2026
- Dnipro River crossing: the river creates a significant military barrier to Ukrainian offensive operations toward the occupied left bank; Ukraine has maintained bridgehead positions but large-scale Dnipro crossing operations have been extremely difficult under Russian fire control of the opposite bank
8. Population Under Occupation
Understanding the demographic situation across occupied territories:
- Pre-war combined population of currently occupied territories: approximately 6.5–8M (Crimea ~2M; Luhansk parts ~1.5M; Donetsk parts ~2.5–3M; Zaporizhzhia parts ~0.5M; Kherson parts ~0.3M)
- Estimated current population under occupation: 4–5M; reductions reflect: displacement to Ukrainian-controlled territories, flight abroad, death from conflict, and movement deeper into Russia
- Demographics of those remaining: significantly older on average than pre-war; those with means to leave and strong Ukrainian identity motivation largely departed; those remaining include elderly with limited mobility and financial means, those with Russian-sympathetic views who stayed or moved from frontline cities, and those who remained from circumstance rather than choice
- Forced transfers: UN and Ukrainian authorities have documented forced transfers of Ukrainian civilians — particularly children — from occupied territories to Russia; the magnitude of child transfers specifically is estimated at 19,000+ confirmed by Ukrainian authorities (higher figures cited in some contexts include transfers to Russia from occupied territories broadly); this formed the basis of the ICC arrest warrant against Putin
9. Russification Policies
Russian occupation administration has implemented systematic Russification across all five regions:
- Administrative: Ukrainian municipal, oblast, and national administrative structures replaced by Russian equivalents; Russian-appointed administrators; integration into Russian federal budget and pension system
- Educational: Ukrainian curriculum replaced; Ukrainian language instruction removed or drastically reduced; Russian textbooks; all children enrolled in Russian educational system; Ukrainian-language schools closed in most areas
- Religious: Orthodox Church of Ukraine (OCU) — the canonical Ukrainian Orthodox church — banned or restricted in occupied areas; properties transferred to the Russian Orthodox Church (Moscow Patriarchate); priests arrested in some cases
- Legal: Russian law applies; Ukrainian property, business registration, and professional credentials require Russian re-registration; courts operate under Russian judicial system
- Identity documentation: Russian passports required for full civic participation; residents without Russian passports face restrictions on employment, banking, property ownership, and movement; the "passportization" policy creates coercive incentives for Russian citizenship acceptance
- Financial: Ukrainian hryvnia replaced by Russian ruble; Ukrainian bank accounts inaccessible; Russian pension system and social payments are often significantly larger than pre-war Ukrainian equivalents, creating deliberate economic incentive for occupation acceptance
10. Civilian Life: Conditions and Surveillance
Civilian life under Russian occupation is characterized by pervasive surveillance, economic hardship for many, and coerced compliance:
- Security services: Russian FSB (Federal Security Service) and Military Counterintelligence are extensively deployed in occupied territories; surveillance of communications, neighborhood informant networks, and checkpoint systems restrict freedom of movement and expression
- Collaboration dynamics: occupation administration requires a layer of local collaborators for administrative functions; collaborators face post-liberation accountability in Ukrainian judicial processes; this creates complex loyalty dynamics for individuals navigating occupation
- Economic conditions: variable. Russian pension and salary levels are often higher in nominal terms than pre-war Ukrainian equivalents for the public sector; private sector disruption and loss of Ukrainian market access has damaged many businesses; sanctions-related goods shortages are significant in some categories; those who retained businesses or land are economically integrated into Russian system whether by choice or compulsion
- Humanitarian access: international humanitarian organizations have extremely limited access to most occupied territories; the UN and ICRC have negotiated minimal access for specific programs; independent reporting on conditions is primarily from those who have left the occupation
11. Resistance and Underground Activity
Ukrainian partisan and intelligence operations in occupied territories are ongoing at levels difficult to fully document:
- Ukrainian intelligence services (SBU and GUR) maintain networks in occupied territories that provide: targeting intelligence for Ukrainian long-range strikes; reporting on Russian military movements, logistics hubs, and deployments; documentation of Russian war crimes and deportations for legal proceedings
- Documented resistance activities: ambushes on Russian occupation officials; assassination of collaborators (multiple confirmed killings of Ukrainian citizens working with Russian authorities); sabotage of rail logistics (particularly effective in 2022–2023); intelligence support for HIMARS strikes
- Civilian passive resistance: documentation by human rights organizations suggests significant non-cooperation at personal level — refusal of Russian passports where possible, maintenance of Ukrainian identity documentation, avoidance of Russian civic and military structures
- Russian counter-intelligence response: sweeps, detentions (hundreds documented by human rights organizations), torture in detention (documented by UN and international human rights bodies), and disappearances of suspected Ukrainian sympathizers or those maintaining contact with Ukrainian territory
12. International Legal Status
The occupation's international legal dimension:
- UN General Assembly: Resolutions ES-11/1 (Mar 2022) and ES-11/4 (Oct 2022) declared Russian military actions and annexation proclamations violations of the UN Charter; adopted with near-universal support (141–143 in favor, 5–7 against, 35 abstentions)
- International Court of Justice: Ukraine filed cases against Russia at the ICJ under the Genocide Convention and other instruments; proceedings ongoing; ICJ provisional measures issued requiring Russia to cease military operations — ignored by Russia
- International Criminal Court: ICC issued arrest warrants for Vladimir Putin and Maria Lvova-Belova (Children's Rights Commissioner) in March 2023 for the deportation of Ukrainian children; Putin cannot travel to any of the 123 ICC member states without risk of arrest
- G7 position: All G7 states maintain non-recognition of Russian sovereignty over any occupied Ukrainian territory including Crimea; this has been maintained formally through the Trump administration, though Trump peace framework discussions have generated concern about de facto recognition through frozen-conflict language
- Frozen assets: Approximately $300–350B in Russian sovereign assets are frozen in Western financial institutions; the legal mechanism for using these funds for Ukrainian reconstruction is being developed through various multilateral instruments
13. Economic Annexation
Russia's economic annexation of occupied territories goes well beyond political administration:
- Agriculture: Zaporizhzhia and Kherson oblasts are among Ukraine's most productive agricultural regions ("breadbasket" areas); Russian occupation has transferred agricultural assets — land, equipment, storage facilities — to Russian-aligned operators; grain stolen from occupied territories and exported was documented extensively in the first years of the war
- Industry: Mariupol's Azovstal and Ilyich steelworks have been seized and assessed for reconstruction under Russian control; Donetsk Oblast's coal mines reassigned to Russian operators; Zaporizhzhia ZNPP's electricity generation potential (when plant returns to operation) would benefit Russia substantially
- Intellectual property and cultural assets: systematic looting of museums (Kherson Regional Art Museum, Melitopol museum collections) documented; cultural heritage removal to Russia is documented by UNESCO and international heritage organizations
- Real property: significant property confiscation from those who left; Ukrainian-owned properties transferred to Russian nationals or occupation-friendly claimants through Russian administrative mechanisms
- Total estimated economic value: the assets contained in occupied territories represent a very significant share of Ukraine's pre-war economic capacity, including approximately 40% of pre-war Ukrainian mineral wealth (coal, iron ore, titanium, other metals within or under occupied territories)
Frequently Asked Questions
- How much Ukrainian territory does Russia occupy in 2026?
- Russia controls approximately 107,000–112,000 km² of internationally recognized Ukrainian territory as of spring 2026 — approximately 18–19% of Ukraine's total land. This includes Crimea (~27,000 km², since 2014), nearly all of Luhansk Oblast (~26,700 km²), approximately 55–60% of Donetsk Oblast, approximately 65–70% of Zaporizhzhia Oblast, and approximately 50–55% of Kherson Oblast. The area is roughly the size of Bulgaria or Hungary — larger than Portugal. The line of control has been relatively stable since late 2022 despite extraordinary casualties on both sides.
- How many people live under Russian occupation in Ukraine?
- Pre-war population of currently occupied territories was approximately 6.5–8M. Current estimated remaining population under occupation: approximately 4–5M, after massive displacement — flight to Ukrainian-controlled areas, flight abroad, death from conflict, and movement to Russia. The remaining population skews older; those with means and strong Ukrainian identity motivation largely departed. The total represents one of the largest forced demographic displacements in European history since WWII.
- What is Russia doing to Russify the occupied territories?
- Russia has implemented comprehensive Russification: (1) Russian administration replacing all Ukrainian structures; (2) Russian passports required for civic participation; (3) Ukrainian curriculum replaced with Russian; Ukrainian language instruction eliminated; (4) Orthodox Church of Ukraine banned; Russian Orthodox Church installed; (5) Russian ruble replacing hryvnia; Russian banking and pension systems; (6) Russian law applying; Ukrainian credentials requiring re-registration; (7) Cultural institutions closed or Russified; (8) Russian-language media environment replacing Ukrainian. The program most advanced in Crimea (12-year occupation) is now being rapidly implemented across 2022-seized territories.
- Does the international community recognize Russia's occupation?
- No. UN General Assembly resolutions (141–143 votes in favor) have declared Russian military actions and annexation proclamations violations of the UN Charter. All G7 states, the EU, and the vast majority of world nations maintain non-recognition of Russian sovereignty over any occupied Ukrainian territory. An ICC arrest warrant was issued for Putin (March 2023) for deportation of Ukrainian children. The Trump administration has formally maintained Ukraine's territorial integrity position while pursuing peace negotiations; Trump's frozen-conflict framework language has generated concern about implicit de facto recognition, but no formal US position change has occurred.
