Which countries did the migrants come from 1945?

After World War II in 1945, migrants primarily came from countries in Europe, especially those affected by the war, such as Germany, Poland, and Hungary. Many displaced persons sought refuge due to the destruction and upheaval caused by the conflict. Additionally, there was significant migration from Eastern European countries under Soviet influence, as well as from parts of Asia, including refugees from China due to the civil war. These movements were driven by the desire for safety, stability, and rebuilding their lives.
