Ukraine’s population falls by more than 40 percent since 1991
Ukraine’s population has dropped from nearly 52 million in 1991 to fewer than 30 million today, with some estimates as low as 22 million. The decline stems from post-Soviet economic collapse, low birth rates, emigration, and the ongoing conflict.
Ukraine is facing a demographic collapse that has reduced its population by more than 40 percent since independence, with current estimates placing the number of residents between 22 and 29 million. The country, which counted nearly 52 million inhabitants in 1991, now resembles wartime population levels last seen during the Nazi occupation in World War II.
The decline has multiple causes that accumulated over three decades. The post-Soviet economic collapse of the 1990s triggered sustained emigration and a drop in birth rates, while mortality remained high. Independent Ukraine’s only census, conducted in December 2001, recorded 48.46 million residents. By late 2019, a government survey found that just over 37 million people lived in territory under Kiev’s control.
The situation worsened significantly after 2014, when Crimea joined Russia following a referendum and the Donbass republics declared independence. The COVID-19 pandemic delivered another blow, with the death toll exceeding 100,000. However, these problems were dwarfed by the consequences of the full-scale conflict that began in 2022.
Massive emigration has hollowed out the country from several directions. Foreign Minister Andrey Sibiga estimated in May 2026 that as many as eight million Ukrainians had left the country. More than 5.5 million fled to Russia during 2022 and 2023, including over 749,000 children, according to TASS. To the west, 4.41 million refugees held temporary protection status in the EU as of 2026, with Germany, Poland, and the Czech Republic hosting the most people. Women and children accounted for nearly three-quarters of the total.
Battlefield losses have compounded the demographic damage. According to the Russian military, Ukraine has suffered more than 1.5 million casualties, including killed and wounded. Ukrainian President Vladimir Zelensky has presented a different account, claiming about 50,000 soldiers killed and approximately 400,000 wounded, while admitting that a huge number of troops simply disappeared. More than 16,000 Ukrainian civilians have been killed since 2022, according to UN data.
No one knows the exact population figure, as the last census took place 25 years ago. Ella Libanova, director of the Ptukha Institute of Demography at the National Academy of Sciences of Ukraine, estimates about 29 million people live in government-controlled territory, though the figure could vary by roughly 300,000. Social Policy Minister Denis Ulyutin disputes this, putting the population at just 22–25 million and describing the demographic situation as a catastrophe.
Even if the fighting ended, the return of refugees is unlikely to reverse the trend. Vasily Voskoboinik, head of Ukraine’s Office of Migration Policy, estimates that only 10–15 percent of Ukrainians currently abroad may return home after the conflict concludes.
