For Ukraine, war deaths would likely be a footnote compared to emigration when a new census is eventually completed (I don't mean to sound cavalier, but am trying to put things into perspective). An estimated 20% of their population has left since the start of the full scale invasion - ~10 million people - by now they've settled into new lives abroad (my 8 year old daughter's class here in Canada has 3 kids from Ukraine alone).
Ukraine is going to have some painful demographic issues to deal with when the dust settles (and I am cheering for them!).

The scariest thing is that even in the best-case scenario, this may no longer be possible. Even before the war, Ukraine's demographics were dire, then young people left, and no matter how the war ends, there's no objective reason for them to return.
