Ukraine is the fastest depopulating country in the world.

Ukraine's population went down 5.8 million in 11 years.

Ukraine's population has declined by 27% from its peak.

It is pretty much guaranteed that the population of Ukraine will fall even further in the years ahead as we cannot expect anybody to be actively willing to return home unless they are deported, and for everybody to wish to leave Ukraine if the war ever ends, or for the population to keep declining if the war keeps going on.

In the long run, win or lose, Ukraine's population is guaranteed to disappear.

One can expect the entirety of Ukraine to become a militarized zone without a civilian population as there is nobody willing to move there and there will never be enough births for the population of the region to go up.

The lowest estimates suggest that Ukraine's population is already down to 37 million.

The higher end count is 41 million.

Conclusion:

Ukraine will win the war but it has no future.

Ukraine today has far fewer births than even South Korea, with a comparatively similar population size.

Population collapse is guaranteed to destroy Ukraine. There is no next generation for Ukraine. All they can do is to move to the European Union.

European Union's population is going to keep increasing till 2050 with the influx of Ukrainians moving into the EU over the coming years.

All the previous predictions and numbers about decline in EU population are now wrong.
