Through United Nations, World War II and Russia

In July 2023, Reuters reported that due to refugee outflows, the population of Ukrainian-controlled areas may have decreased to 28 million, a steep decline from Ukraine's 2020 population of almost 42 million.

This drop is in large part due to the ongoing Ukrainian refugee crisis and loss of territory caused by Russo-Ukrainian war, which resulted in mass emigration. The demographic decline is also affected by a very low birth rate and a high mortality rate. The most recent (and only) census of post-Soviet Ukraine occurred in 2001, and much of the information presented is potentially inaccurate or outdated.

Since 2021, the Ukrainian fertility rate has fallen below 1.3, and is now one of the lowest in the world. By 2024, it was one of the ten lowest in the world, falling under 1.00.

History

Historical population

There were roughly four million Ukrainians at the end of the 17th century. However, population estimates from this period are approximate and may vary depending on methodology and available records.

The estimated population figures for Ukraine in the early 20th century are based on various sources. The 1931 population statistics were estimated by Professor Zenon Kuzelia, as an official census was not conducted in Soviet Ukraine during that year.

Data for 1926–2001 is based on official Soviet and Ukrainian censuses. The 2014 and 2020 figures are adjusted estimates, excluding Crimea and occupied territories in Donbas.

Natural change and migration
