Apologies if my question is poorly worded; after reading a work of fiction detailing the life of a Jewish family in pre-War Germany I became curious as to whether Jews had returned to make their home in Germany despite the shadow of the Final Solution hanging over them. Has Germany's Jewish population returned to a 'normal' level, or are there noticeably less Jews living in Germany, even today?
The global Jewish population has not recovered to pre-Holocaust numbers.
The 1939 global Jewish Population was 16.7m and was 13.9m in 2014.

The Jewish population in Europe was 9.5m in 1939, and 1.4m in 2010.

The Jewish population in Germany was 118,000 in 2014.

The Jewish population in Germany at the time of the census in 1933 was 505,000. It is estimated to have been 523,000 at the end of 1932, but some had already fled Germany after the Nazi takeover by the time of the census.

So, there are about 1/5 as many Jews in Germany today as there were before the Nazis.
Note: All these demographic numbers have some unreliability, as not all people identify by religion consistently in censuses.
Rounding out the statistics above, as a Jew living in Germany, I'd add that only Munich and Berlin have anything approaching a serious Jewish community and the former's is quite small.
Furthermore, although I don't have stats on this, a sizeable amount of the Jewish population here are not descendants of German Jews, but largely people who immigrated from the USSR in the 70s and 80s due to government-sanctioned antisemitism there during that time.
Before and after WWII most German Jews immigrated to the US, UK, and Israel.
