The correct answer is a high number of refugees forced to relocate.
The pressure placed on the Jewish people in Germany was the main factor that forced a high number of refugees to relocate.
The number of Jews in Germany in January 1933, were about 523,000. These Jews decided to leave the country after the Nazi takeover. Emigration numbers were mostly 37,000 and they went to Belgium, Denmark, France, the Netherlands, and Switzerland, which always demonstrated an openness to receive the Jewish immigrants.
