Reply To: What percentage of conservative and reform are halachically jewish?

Intermarriage for the last decade plus amongst the non-Orthodox has been at about 75%. 3 out of 4 non-Orthodox marriages are to a gentile.

And it didn’t go to 3/4 rapidly. It worked is way up to that dismal figure over a long period of time.

And even where the mother is Jewish and the father non-Jewish, those children are raised as non-Jews in the vast majority of cases.
