There were not many Jews in Germany at the time of the WW2. Germany was home to 566,000 Jews in the early 1930s (less than 1% of the total population). Compare this to 3,250,000 in Poland (11% of the population) and 725,000 in Hungary (10% of the population). Also, most of the German Jews emigrated to North America and the United Kingdom during the mid-1930s. Around 25% of the German Jews stayed behind in Germany at the time of the WW2, and were exterminated. On the other hand, 75% of the Hungarian Jews, and 90% of the Polish Jews were exterminated by the Nazis.
Just to make a few things a bit more factual.
725,000 was the number of all jews in Hungary (reannexed territories included) and that was 4,9% of the population according to the official holocaust literature and 600,000 were deported (90% died). (Source: wikipedia)
According to the Hungarian Central Statistical Office (1941 census) that number is actually 431,711 and approximately 200,000 were deported but no exact data is available as things got a bit messy and not very well documented when the soviet army reached Hungary in 1944 and the germans occupied the rest of the country. Since the end of the war no data is available but the state paid/paying compensations for about 33,000 holocaust survivors, what makes the number of victims something like 167,000.
