The Pew Research Center, which does by far the most comprehensive polling and statistics on things like this, published a study in 2021 titled “Jews in the U.S. are far less religious than Christians and Americans overall, at least by traditional measures." As the title suggests, it discusses the disparity in religious belief and observance between Jews and the rest of the country, and the results are worrying. They use a fairly consistent cross-section of Orthodox, Conservative, Reform, and unaffiliated Jews to mimic the actual demographic of American Jews. For more context, you can view their full methodology for this specific study here.
Here are some of the results:
For example, 12% of U.S. Jewish adults say they attend religious services weekly or more often, compared with 27% of the general public and 38% of U.S. Christians.
That means if I take your average guy off any street in America, there is a higher chance that he is attending a weekly religious service than your average Jew is showing up to Friday night minyan.
There are even bigger gaps when it comes to belief in God. About a quarter of Jews (26%) say they believe in God as described in the Bible, compared with more than half of U.S. adults overall (56%) and eight-in-ten Christians.
Although:
Jews are more likely than U.S. adults overall (50% vs. 33%) to say they believe in some other spiritual force or higher power, but not in God as described in the Bible.
And not surprising, Jewish identity charts way higher than Jewish orthopraxy:
In fact, twice as many Jews say “being Jewish” is very important to them as say their religion is very important to them (42% vs. 21%).
On the other hand, Orthodox Jews are one of the most religious groups in the country.
For example, 86% of Orthodox Jews say religion is very important in their lives, as do 78% of black Protestants and 76% of white evangelical Protestants, two of the most highly religious Christian subgroups.
and
Orthodox Jews (93%) are also about as likely as white evangelicals (94%) and black Protestants (88%) to say they believe in God as described in the Bible.
So the picture emerges of a religion with a highly religious sub-group, the Orthodox, against the backdrop of a strongly non-religious majority. Is there any way forward that doesn't involve the complete assimilation of the majority of Americans while a small minority gradually takes over? I don’t know. How did this happen? As all of Jewish history, it is a long and complicated story.
"A 2020 survey conducted in the United States by the Pew Research Center found that 42% of all currently married Jewish respondents indicated they have a non-Jewish spouse. Among those who had married since 2010, 61% were intermarried and the percent increases to 72% when Orthodox Jews were excluded from the data." -- Wikipedia, https://bit.ly/4bzLFU2
Other sources quote a 70% intermarriage rate among non-Orthodox American Jews, since the 1970s. IOW, very few of the now 2nd (3rd?) generation American Jews since the 1970s are, in fact, "Jews". What are they? They're the modern-day equivalent of the ערב רב -- the "mixed multitude" who tagged-along when our ancestors left Egypt. And today, in practice, they're the "'Jews' for Justice for Palestinians", the "Jewish Voice for Peace", the "'Jews' for Jesus", the "Court Jews" like Mayorkas, Blinken, and so many others.
We need to repudiate them... and the sooner, the better.
We know that catastrophic and near disastrous events as well as a rise in anti Semitism awaken in many a sense of Hirhurei Teshuvah , rethinking and discovering what it means to be a committed Jew .This is evident since 10/7 among many of our brothers and sisters who thought they were part of the woke world or who had never explored any aspects of their tradition in both the US and Israel We need to reach out to our brothers and sisters one Mitzvah at a time
