Comparing rape statistics between countries is a poor measure for estimating violence in society, due to the different legal definitions and differences in willingness of victims to report it. There is some discussion of the issues here:
I quote one paragraph relating to Germany, as you mention it: https://worldpopulationreview.com/country-rankings/rape-statistics-by-country
" Sweden's seemingly oversized rape rate is perhaps the best-known example of this scenario. During the years 2013-2017, Sweden averaged 64 reported rapes per 100,000 inhabitants—a rate that tied for the highest in Europe. However, when the data was examined, it became clear that Sweden's high numbers were fueled in large part by Sweden's broader definition of rape and more inclusive reporting rules compared to other European countries. When the data was recalculated using Germany's narrower guidelines, for example, Sweden's average reported rapes per 100,000 people fell from 64 to 15, a decrease of 76.56%."
