How the two compare
In 2025 Russia has 3.68× as many people as Ukraine: 144 million against 39 million. The difference is 105 million. Ukraine would fit inside Russia 3 times over. Together they hold 2.2% of the 8.19 billion counted here.
Then and now
In 1960 the order was Russia ahead, 120 million to 42.8 million, a ratio of 2.8×. Since then Russia has grown 1.2× and Ukraine 0.91×, averaging 0.28% and -0.14% a year.
The lines never cross between 1960 and 2050: Russia stays ahead throughout, and the gap widens by 2050.
Towards 2050
Projected to 2050, Russia reaches 137 million (4.2% fewer than today) and Ukraine reaches 32 million (17.9% fewer). By then the ratio is 4.3× in favour of Russia.
Land and people
Land changes the picture: Russia has 16,376,870 km² and 9 people per km², Ukraine has 579,400 km² and 67 per km². Ukraine is 7.68× more densely settled.
Behind the totals, fertility is 1.42 in Russia and 0.99 in Ukraine; life expectancy is 73.4 against 74.7 years; 17.8% against 19% of people are 65 or older. The younger the population, the longer it keeps growing after birth rates fall.
Where the numbers come from
Figures are the World Bank's "Population estimates and projections" series, built from United Nations and national statistics. Values up to 2025 are estimates; 2026–2050 are projections that assume current fertility, mortality and migration trends continue, so they are not forecasts of events such as wars or policy changes. Territories are listed as the World Bank lists them, and a small number of places have gaps in some years.
