What was a notable effect of WWII on the population of Europe and Asia?

The notable effect of World War II on the population of Europe and Asia was indeed mass homelessness and casualties. The war resulted in devastating loss of life, with millions of soldiers and civilians killed, injured, or displaced. Cities across both continents faced significant destruction due to bombings, battles, and military occupations, leading to a severe humanitarian crisis. Many people were left homeless as their residences were destroyed, and vast populations were uprooted, leading to refugee crises as people fled war-torn regions for safety. The impact of these losses and displacements created long-term challenges in recovery and rebuilding for the affected nations, shaping the social and political landscapes of the post-war period. This period not only highlighted the immediate humanitarian needs but also set the stage for subsequent political changes, including decolonization efforts in various parts of Asia.
