Here is a map that changes from pre invasion until now.
One of the points of the article is that people were already leaving Ukraine in droves even before the “invasion”. The invasion made it easier for women and children to leave. Today, the resident population is estimated at between 28 and 31 million” dropping 10 to 12 milllion since the "invasion" began.
Bodes not well for any type of post war “ Reconstruction “. Very near sighted thinking. Fact is, there will be no one left with the skills to attempt rebuilding, nor anyone left to administer the civilian infrastructure.
Fact is, very, very few Ukrainians will return. “ Rebuilding” will no doubt be attempted with very low paid aliens, extending the Ukrainian poverty cycle ( They were / are the poorest nation in Europe).
