The civilian population residing in Ukrainian-controlled areas of Donetsk Oblast fell to approximately 93,600 people as of September 1, 2026, according to official regional figures. Data provided by the Donetsk Regional Military Administration in response to an inquiry by Radio Free Europe's Donbas Realities project revealed that about 4,800 children remain in government-held territory across the war-torn eastern region.
The new figures highlight a dramatic demographic contraction over the past 14 months as heavy fighting continued along the eastern front. On June 30, 2025, official statistics recorded 269,100 civilians living in Ukrainian-held parts of Donetsk Oblast. Since then, the civilian population in the free areas has shrunk by nearly two-thirds, marking an overall drop of 65 percent.
Evacuation efforts intensified throughout the summer months as authorities urged civilians to leave areas exposed to shelling and ground combat. During the three months of summer, approximately 48,700 residents departed from Ukrainian-controlled territory, either through organized government evacuations or by self-evacuation. Among those who left during the summer period were around 3,700 children.
Donetsk Oblast forms part of the industrial Donbas region in eastern Ukraine, an area historically known for its heavy industry, coal mining networks, and dense urban centers. Following the onset of Russian-backed conflict in 2014 and the loss of control over the regional capital of Donetsk, Ukrainian authorities transferred the administrative functions of the oblast to the northern city of Kramatorsk, which has since functioned as the regional center.
Civilian presence in frontline communities
The military administration provided specific civilian population counts for six key communities located near the active battle lines. Kramatorsk remains the largest urban center under Ukrainian control in the oblast, holding 39,200 residents. The neighboring city of Sloviansk maintains a population of 26,400. In smaller frontline communities, figures stand at 5,500 residents in Mykolaivka, 2,590 in Druzhkivka, 2,100 in Lyman, and 780 in Kostiantynivka.
Children are now reported present in only two of the six frontline communities. Official records list 2,070 children in Sloviansk and 1,500 children in Kramatorsk, with no children remaining in Mykolaivka, Druzhkivka, Lyman, or Kostiantynivka. Ukrainian authorities have frequently implemented compulsory evacuation mandates for families with minors in settlements closest to active artillery range to prevent civilian casualties.
The cities of Sloviansk and Kramatorsk together form a primary urban agglomeration in northern Donetsk Oblast. Located along major rail and road corridors, the area serves as a key logistical hub for civil administration and humanitarian relief. Settlements such as Lyman, positioned near the forested border with Luhansk Oblast, and Kostiantynivka, situated further south toward active combat sectors, have frequently been targeted by long-range artillery and aerial bombardment.
Shift in territorial control and military operations
The reduction in civilian population matches a gradual increase in the territory occupied by Russian forces in the region over the same 14-month timeframe. Statistics from the Donetsk Regional Military Administration indicate that the estimated proportion of temporarily occupied land in Donetsk Oblast expanded from 66.7 percent on June 30, 2025, to 73.43 percent as of September 1, 2026.
Regional officials noted that the September 1 figure of 73.43 percent occupation does not capture territorial gains made during Ukrainian counter-offensive maneuvers under Operation Vivaldi. Andriy Biletskyi, commander of the 3rd Army Corps and the Center operational grouping, reported that Ukrainian Defense Forces have liberated a total of 176 square kilometers of territory in the region since offensive actions commenced.
Andriy Biletskyi is a well-known Ukrainian military officer who commands the 3rd Army Corps, a tactical formation of the Ukrainian Armed Forces actively deployed in high-intensity combat operations across the eastern sector. The statistics were published by Donbas Realities, a dedicated regional project of the United States funded broadcaster Radio Free Europe/Radio Liberty, which has reported on human rights, civilian displacement, and military operations in Donbas since 2014.
