About 15 percent percent of the population has fled Ukraine since the start of the Russian aggression in February 2022. Nearly 4 million Ukrainians have already registered in European Union countries. Based in part on evidence that few refugees return voluntarily to poor countries once they settle in rich countries, even once security is re-established at home, it can be expected that large numbers of Ukrainian refugees are likely to remain in European host countries, and will likely be joined by others, including many men that remained to fight when the conflict is over.
