By BERNIE BELLAN A recent report from the Pew Research Center offers some interesting information about adult Jews in Israel and the United States. According to the report, 80% of the world’s Jews live in those two countries – which explains why there is no reporting about Jews in other countries.

Similar to the situation we reported on with respect to the Census of Canada in 2021, the Pew Report notes that “people may identify as Jewish in a multitude of ways, including ethnically, culturally, religiously or by family background. In this report, we use the term “Jewish” to mean only religious identity, because the survey questions used in the analyses ask about a person’s current religion and what religious group they were raised in (their childhood religion).”
It should be noted that the Canadian census allowed respondents to identify as Jewish both by religion and by ethnic identity. As a result, there were great disparities in the numbers who responded they were Jewish in both categories.

In a December 2023 article we noted that “Of all Winnipeg respondents only 6,700 reported that both their ethnic origin and their religion was Jewish. Yet, 10,700 people in total reported that at least one of their ethnic origins was Jewish, while 11,170 reported their religion was Jewish.”
As a result, after we did a cross-comparison of figures for both categories, we arrived at the conclusion that, at a maximum, the total possible number of individuals who identified as Jewish – either by religion or ethnicity, was 14,270. (But, when you consider, for instance, that of the 10,700 respondents in the census who reported their ethnic origin as Jewish, 1,080 reported their religion as Christian, it gives you some idea how amorphous Jewish identity is.)

The Pew Report, as noted, concentrated only on determining how many Jews in Israel and the United States reported their religion as “Jewish.”
Some of the findings of the report were:
• Most people who were raised Jewish in Israel and the U.S. still identify this way today, resulting in high Jewish retention rates in both countries – though it’s higher in Israel than in the U.S.

Leaving Judaism
• In the U.S., about a quarter of adults who were raised Jewish no longer identify as Jewish.• In Israel, fewer than 1% of adults who were raised Jewish no longer identify as such.

• Most adults who have left Judaism in both countries now are unaffiliated (i.e., they identify religiously as atheist, agnostic or “nothing in particular”).

Entering Judaism
• Most Jewish adults in Israel and the U.S. were raised Jewish, meaning the “accession” (or entrance) rates into Judaism are fairly low in both places.
• But of the two countries, the U.S. has the higher accession rate, with 14% of Jewish Americans saying they were raised outside of Judaism, compared with just 1% of Israeli Jewish adults.

The report delved further into the question of the affiliation of individuals who said their religion was Jewish, but who no longer identify as Jewish.
• In Israel, only 1% of individuals who were raised Jewish said they are now not religiously affiliated. (The number who said they now had another religion was so low that the Pew Report gave the figure as 0. I wonder though, how “Jews for Jesus” – which has a considerable following both in Israel and the U.S. would be taken into account in reports about the number of Jews in the world? Are “Jews for Jesus” still Jewish – even if they consider themselves Jewish? It’s questions like this that make me wonder about the reliability of surveys that claim to provide credible information about how many Jews there are in the world.)
• In the U.S., however, the Pew Report noted that “17% of adults who were raised Jewish now identify as unaffiliated, while 2% now identify as Christian and 1% now identify as Muslim.”

In an earlier study, conducted in 2021 also by the Pew Research Centre, Jews were asked what were the most important aspects of their identifying as Jewish. I’ve written about that report before because I found the answers so fascinating. (I’ve noted that having a good sense of humour was considered an essential part of being Jewish by 33% of respondents, as opposed to only 3% who said that observing Jewish law was an essential part of being Jewish. But don’t tell that to the Winnipeg Council of Rabbis, who insist that the Simkin Centre serving kosher food – even when almost half its residents aren’t even Jewish, is essential to the Simkin Centre.)
Here, again, are the results of that survey:
