From Exodus to Freedom: The History of the Soviet Jewry Movement Book

Most of this book is about post World War II "D.P." (displaced persons) camps in Germany. I had always thought most D.Ps were Jews, but in fact many of them where non-Jewish refugees from newly Communist Eastern Europe. This book focuses on Jewish D.Ps. Some of the surprisin things I learned were:
1. I had always thought that most Jewish D.Ps had been in concentration camps; the author thinks, however, that many of them fled to the Soviet Union to avoid Nazism, survived the war in the Soviet Union, discovered after the war that their Eastern European hometowns were unwelcoming or dangerous, and then fled to the D.P. camps.
2. I had always thought of D.P. camps as sealed off from their German neighbors; but in fact they needed Germans in a wide variety of service jobs (e.g. plumbers, doctors etc). About 20 percent of D.Ps lived on their own in German towns, where they interacted even more with local Germans.
3. I was vaguely aware that Jews in the D.P. camps were eager to make up for lost time by getting married and having children- but I had no idea how eager. One estimate was that Jewish D.Ps had 50 births per 1000 people in 1947- roughly seven times the German birth rate at the time. Jews also had about ten times as many weddings as Germans.
The book also discusses Germans (who were very traumatized by the war in Berlin, but often were unaffected if they lived in rural areas far from combat) and surviving Berlin Jews (most of whom were elderly and highly assimilated).
