According to the United Nations, Ukraine has a population of 37.9 million as of 2024.
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.
The total fertility rate (TFR) of a population is the average number of children that are born to a woman over her lifetime, if they were to experience the exact current age-specific fertility rates (ASFRs) through their lifetime, and they were to live from birth until the end of their reproductive life.
As of 2023, the total fertility rate varied widely across the world, from 0.7 in South Korea, to 6.1 in Niger. Among sovereign countries that were not city states or microstates, in 2024 the following countries had a TFR of 1.0 or lower: South Korea, Taiwan, Thailand and Ukraine; the following countries had a TFR of 1.2 or lower: Argentina, Belarus, Chile, China, Colombia, Costa Rica, Estonia, Italy, Japan, Lithuania, Poland, Spain, and Uruguay.
The 2001 Ukrainian census is to date the only census of the population of independent Ukraine. It was conducted by the State Statistics Committee of Ukraine on 5 December 2001, twelve years after the last Soviet Union census in 1989. The next Ukrainian census was planned to be held in 2011 but has been repeatedly postponed.
The total population recorded in 2001 was 48,457,100, of which the urban population was 32,574,500 (67.2%), rural: 15,882,600 (32.8%), male: 22,441,400 (46.3%), female: 26,015,700 (53.7%). The total permanent population recorded was 48,241,000.

The next Ukrainian census is planned to be conducted by the State Statistics Service of Ukraine. The 2001 census was the most recent, and the only census conducted in independent Ukraine to date. The next census was to have been held ten years later, in 2011 (censuses should be conducted every ten years, according to standards set by the United Nations). However, the next census has been regularly delayed and a date for a new census has not been set.
The 2001 census recorded the population of Ukraine as 48,457,100 people. By May 2021, that population had dropped down to 41,442,615(excluding Crimea and Sevastopol).
