What percent of Germans where Nazis in WWII?

During World War II, approximately 10% of the German population were members of the Nazi Party at its peak. This accounted for around 8 million people in a country of about 80 million at the time. However, it's important to note that many more Germans supported the regime or were complicit in its activities without being formal party members. The level of active support and involvement varied significantly across different segments of the population.
