Under the microscope: New study offers unprecedented insight into diaspora Jewish identity after October 7

In the flood of commentary and conjecture that followed the Hamas attacks of October 7, 2023, one question has echoed through Jewish communities worldwide: Has this moment fundamentally changed what it means to be a Jew in the Diaspora?

Now, we have rigorous empirical data to answer that question — at least for British Jewry. Dr. David Graham's landmark report, "'October 8 Jews': The impact of October 7 on British Jewish identity," published by the Institute for Jewish Policy Research (JPR), is a methodological triumph that cuts through the noise of anecdote and speculation to deliver something far more valuable: the truth.

This is not another snapshot survey hastily assembled in the wake of tragedy. It is a longitudinal study of rare power — following the same several thousand British Jews over a six-year period, linking their responses wave by wave, allowing us to measure actual change before and after October 7 with a precision that cross-sectional data simply cannot match. In the world of quantitative survey methodology, this is the gold standard. And JPR has wielded it with admirable skill.

The Findings: Strengthened Israel Attachment, Enduring Anxiety, and a Nuanced "Surge"

The picture that emerges is one of significant change alongside striking continuity — a nuanced portrait that should inform Jewish leadership and policy for years to come.

First, the headline: British Jews became notably more attached to Israel. Emotional attachment rose modestly overall — from 72% in May 2023 to 76% in June 2024 — but the intensity of that attachment surged dramatically. The proportion saying they were "very" emotionally attached to Israel jumped from 38% to 50% in the nine months after October 7, and remained elevated at 51% twenty months later. This was no momentary spike. It was a durable shift.

Even more striking: the proportion who said supporting Israel was "very important" to their Jewish identity rose from 35% to 48% — a 13-percentage-point leap that held steady over time. Self-identification as Zionist climbed from 61% to 67%. Consideration of aliyah rose significantly. And the prioritization of Israel-related charitable causes nearly tripled, from 6% to 16% by June 2025 — the only Israel-related measure that continued to grow over time rather than merely plateau.

These are not trivial changes. They represent a profound reassessment of Israel's place in the lives of British Jews.

The Shadow Side: Rising Antisemitism and Declining Safety

Yet this strengthening of Israel attachment and Jewish peoplehood occurred against a backdrop of profound insecurity. The report is unflinching in documenting the dark reality that followed October 7.

The proportion of respondents who experienced at least one antisemitic incident nearly doubled — from 17-20% in the years prior to 29% in the eighteen months spanning October 7. Reports of verbal antisemitic attacks quintupled (from 2% to 10%), and online abuse more than tripled. Concern about antisemitism as a problem in the UK skyrocketed: the proportion saying it was a "very big problem" rose from 18% in May 2023 to 46% in June 2024 — nearly tripling — and remained at 50% by June 2025.

Feelings of safety as a Jewish person in the UK fell sharply, from a mean score of 7.4 in May 2023 to 6.2 in June 2024, and further still to 5.8 by June 2025. Anxiety levels among British Jews diverged dramatically from the general population, reaching 3.8 compared to 3.2 nationally — a striking gap given how similar these figures had been historically.

Dr. Graham is careful to note the causality: the anxiety increase was driven primarily by concern about antisemitism in the UK, not by concern for Israel's security. Emotional attachment to Israel showed no association with anxiety levels. This is an important finding for those seeking to understand and address the mental health toll on British Jewry.

What Did Not Change: The Resilience of Jewish Identity

Perhaps the most surprising — and, in some ways, reassuring — finding is what did not change.

Despite widespread talk of an "October 8 Jew" or "the Surge," the JPR data reveal no broad transformation in Jewish religiosity or communal participation. Synagogue attendance remained essentially flat. Jewish learning showed no measurable increase. General charitable giving and overall strength of Jewish identity were unchanged. There was no evidence that previously disengaged Jews became substantially more involved in Jewish life.

Feelings of attachment to the local Jewish community did rise initially — from 64% to 71% — but fell back to 67% by June 2025, suggesting even this was a temporary phenomenon. As Dr. Graham notes, this "challenges the notion of a British 'Surge,' or the 'October 8 Jew': i.e. the idea that less engaged Jews in particular 'woke up' after October 7."

This is not a reason for disappointment. It is evidence of something perhaps more valuable: resilience. Faced with exceptional levels of antisemitism and insecurity, British Jews did not withdraw from Jewish life. Their identity did not erode. Jewish life continued.

A Methodological Triumph

It must be said: this report is a model of what rigorous social science can accomplish. JPR's longitudinal panel — running for several years prior to October 7 — presented a serendipitous opportunity to measure actual change, not retrospective accounts skewed by memory and emotion. As Dr. Graham explains, longitudinal data have "several important advantages over cross-sectional data. They measure actual change in opinions and behaviours over time and can be confidently anchored to a particular trigger."

The report is transparent about its limitations — attrition, the challenges of sub-group analysis over time, the possibility of missing transient spikes. But these caveats only strengthen confidence in the findings. This is not advocacy masquerading as research. It is empirical inquiry at its finest.

The Challenge Ahead: From Solidarity to Participation

Dr. Graham concludes with a challenge that should resonate far beyond Britain's shores: "The challenge for community leaders and educators now is to shape these strengthened feelings of connection into something more broadly impactful. There were no easy answers to strengthening Jewish identity before October 7, and there are none today. But there is now an opportunity to convert solidarity into participation, concern into commitment, and attachment into engagement."

This is the right question, framed the right way. The JPR data show that British Jews emerged from October 7 with a clearer appreciation of Israel's importance to them personally and a stronger sense of belonging to the Jewish People. These are precious resources. But they are not self-sustaining. As Dr. Graham warns, the rise in solidarity occurred alongside anxiety and fear — "a fragile foundation upon which to build Jewish life."

The task now is to transform these emotional shifts into enduring behavioral change. To move from feeling more attached to Israel to engaging more deeply with it. To move from a sense of Jewish peoplehood to active participation in Jewish community. To move from resilience in crisis to genuine flourishing.

A Model for the Diaspora

While this study focuses on Britain, its implications extend far beyond these shores. Jewish communities worldwide have grappled with the same questions since October 7. The JPR report provides a template — both methodologically and substantively — for understanding how Diaspora Jews have responded to this watershed moment.

The findings should be read by every Jewish communal leader, educator, and policymaker. They should inform strategic planning, resource allocation, and program development. They should temper both excessive optimism about a "Surge" and excessive pessimism about Jewish disengagement.

Most of all, they should inspire a deeper commitment to the hard work of building Jewish life — not merely in response to crisis, but in pursuit of something more enduring.

Conclusion: A Vital Contribution

Dr. David Graham and the team at JPR have done the Jewish world an immense service. This report is rigorous, honest, and deeply insightful. It refuses easy answers and comfortable narratives. It tells the truth — even when that truth is complex.

October 7 was a watershed. But as this report demonstrates, the nature of that watershed is not what many assumed. British Jews became more attached to Israel and more conscious of their Jewish peoplehood. But they did not become more religious, more observant, or more engaged in communal life. The "October 8 Jew" is real — but only in a specific, limited sense.

This is not cause for despair. It is cause for clear-eyed determination. The resilience of British Jewry is remarkable. But resilience is not renewal. The opportunity now is to build on these strengthened foundations — to transform solidarity into participation, concern into commitment, and attachment into engagement.

The JPR report shows us where we are. The challenge now is to decide where we go from here.
