Regarding France I was mistaken - actually most of its civilian losses were Non-Jews.
And survival ratio of French Jews was very high.
But several questions need to be asked:
Do we know what % of French Jews as of 1940 could speak French language fluently, and what % of French Jews were religious, especially Orthodox (while what % were Atheists, or converts to Christianity). Also what was the % of survivors among Jewish refugees in France, and what among native Jews of France?
Large groups of Jews from Germany and also some from other countries escaped to France.
But those Non-French Jews overwhelmingly perished in the Holocaust, unlike native French Jews.
Being non-religious, Christian, or at least non-Orthodox and speaking fluently the language of local gentiles, was vastly increasing your chances of survival as a Jew or person with Jewish ancestry.
Most of native French Jews survived because they were not "detected" as being Jews.
French Jews were among the least religious and the most well-assimilated into the culture of local gentiles among whom they lived. This is why France had such a large survival ratio of Jews - if we call those acculturated French Atheists or Catholics with Jewish or partially Jewish ancestry, Jews.
