JTA: This map shows the 20 congressional districts with the most Jews

September 10, 2020

About one-third of American Jews live in just 20 of the country’s congressional districts. Nearly half of those districts are in New York, and all but one of them is represented by a Democrat.

Meanwhile, the district with the most Jews in the country is also the site of Mar-a-Lago, President Donald Trump’s Florida estate.

Those are among the findings from a  recent study  analyzing Jewish voting patterns. Key findings from the study, which was conducted by the Jewish Electorate Institute and the Steinhardt Social Research Institute at Brandeis University, were published online Aug. 25.

The study, like previous others, found that Jewish voters are more Democratic and politically liberal than the country at large. It also found, similar to earlier research, that Jewish voters tend to be older than average.

What’s new here is that the researchers were able to identify not only how Jews vote but where they cast their ballots. The study found that the majority of Jewish adults live in four states — New York, California, Florida and New Jersey.

“In all of the so-called battleground states, not only Florida but places like Pennsylvania and Ohio and Michigan, those are states where if something similar to 2016 happens in 2020, Jews are large enough in number in those states where they could make a difference,” said Leonard Saxe, director of the Steinhardt Social Research Institute.

Approximately one-third of Jewish adults, about 1.8 million, are concentrated in just 20 congressional districts among the 435 across the United States.

The district with the most Jewish voters, Florida’s 21st, is drawing a lot of attention this year for its race between two Jewish candidates, the Democratic incumbent Rep. Lois Frankel and Laura Loomer, an anti-Islam provocateur who  won the Republican nomination  and  Trump’s endorsement. Loomer released an  ad this week that used Holocaust imagery  and Yiddish to attack Frankel as an opponent of Jewish interests.

The district covers southeastern Florida cities such as Palm Beach, Boynton Beach and Delray Beach, and includes 152,000 Jewish adults, according to the study. In total, the district has about  524,000 registered voters. According to the study, the district is 24.3% Jewish, and more than half of those Jewish adults are older than 65.

The two adjacent districts down the South Florida coast, the 22nd and 23rd, also crack the top 20 for Jewish voters. Both are also represented by Jewish Democrats: Reps. Ted Deutch and Debbie Wasserman-Schultz, respectively.

Most of the other districts in the Jewish top 20 are in New York and New Jersey, including seven in New York City and two on suburban Long Island. The second-largest Jewish district overall, New York’s 10th on the Upper West Side of Manhattan, has 151,000 Jewish adults and is represented by longtime congressman Jerry Nadler, a Jewish Democrat. The other New York City districts cover large swaths of Manhattan, Brooklyn, Queens and Staten Island.

The lone district on the list represented by a Republican, Rep. Chris Smith, is New Jersey’s 4th, which includes the heavily Orthodox city of Lakewood. That district is about 10% Jewish, with 51,000 Jewish adults, according to the study.

The rest of the top 20 districts are in Los Angeles County and the suburbs of Chicago, Philadelphia, Baltimore and Boston.

Overall, eight of the top 20 Jewish districts are represented by Jews. Saxe said the list of the most Jewish districts is a key data point ahead of the 2020 census, which will likely lead to congressional redistricting.

“The concentration of Jews and whether that concentration is allowed to continue, whether it’s not, will be an important issue,” he said. “In those districts where Jews are 10% or more of the population, they’re also a very significant force in choosing members of Congress.”

In the nearly two years since Hamas’s brutal Oct. 7 attack on Israel, American Jews have watched a disturbing rise in antisemitism take place across America — and crucially, among some of our longtime allies. For decades, Jewish Americans stood at the forefront of progressive causes, marching for civil rights, fighting for reproductive freedom and advocating for immigrants and the marginalized. My Jewish faith is what first drove me to public service. The Jewish concept of tikkun olam — our responsibility to repair the world — is not just a religious tenet but a moral call to action. It’s why we’ve always shown up to defend others. Yet now, as antisemitism surges to record levels, many progressive organizations and leaders who once stood with us have gone quiet; or worse, turned their backs entirely. It’s no longer just about Israeli policy. The line between anti-Zionism and antisemitism has been crossed so many times it’s barely a line at all. “Zionist” has become a stand-in for “Jew,” and the message is clear: Unless you disavow the world’s only Jewish state, your place in many progressive spaces is no longer welcome. The picture is sobering. There have been calls to ban “Zionists” from Pride events. Many women’s groups have shrugged at Hamas’ rape of Israeli women. And the Democratic nominee for mayor of America’s most populous city has a pattern of antisemitic rhetoric and has refused to condemn the hurtful call to “globalize the intifada,” a rallying cry that has been used to incite violence against Jews. This didn’t happen overnight, but the silence from many who claim to fight for justice has been deafening and deeply painful. I know what it feels like to be targeted for who you are. In January 2020, shortly after I became the first woman and the first Jewish Speaker of the Virginia House of Delegates, the FBI uncovered a plot to assassinate me. Two members of a neo-Nazi domestic terrorist group had targeted me. It was the most serious of many threats I received during my time as Speaker. Thankfully, law enforcement intervened in time. But the threat was real, and it reminded me that hatred knows no single party or ideology. We’ve long seen this kind of extremist hate on the right, but today that same danger is rising on both extremes of the ideological spectrum. Antisemitism spreads under different names but with the same devastating consequences. Now, with the recent war between Israel and Iran, we’re likely to see a fresh wave of anti-Zionism and antisemitism. It is already giving rise to a new round of dangerous conspiracy theories laced with antisemitic tropes: accusing American Jews of dual loyalty; suggesting we control foreign policy; and portraying Jewish political engagement as part of a shadowy cabal influencing Washington. This is a moment of moral testing. Will our leaders speak clearly and forcefully against antisemitism, even when it’s politically inconvenient? Will those who champion diversity and inclusion apply those values to Jews as well? And will we be honest about how bad actors have exploited division, stoked extremism and enabled those who traffic in hate? Just as many Americans oppose President Donald Trump’s leadership while still loving this country and believing in its promise, the same is true for Israel. You can criticize or reject Prime Minister Netanyahu’s government and still support Israel’s right to exist, to defend itself and to thrive as a Jewish and democratic state. That distinction matters. Criticizing a government is not the same as condemning a people; but when it comes to Israel, that line is too often deliberately blurred. We must be able to hold leaders accountable without fueling hatred or questioning a nation’s fundamental legitimacy. Antisemitism is not merely a problem faced by Jews — it is a bellwether for the health of our democracy. When a society tolerates hatred against one group, it gives license to hate others. When threats against public servants go unchallenged, violence becomes normalized. I was reminded of that tragic reality when my friend and former counterpart, former Minnesota House Speaker Melissa Hortman, was executed in her home along with her husband, Mark. Authorities say her killer was a politically motivated extremist who had compiled a list of Democratic lawmakers. Melissa was a principled leader and a friend. Her death was a heartbreaking loss and a flashing red warning sign for the tolerance of hate in our democracy. We cannot afford to treat this moment as normal. It is time for our allies to rejoin us. To speak up when we are threatened. To see antisemitism for what it is: a growing, dangerous force that must be confronted head-on. Because if we wait until it affects everyone, it will already be too late.

July 1, 2025 U.S. House Committee On The Judiciary 2142 Rayburn House Office Building Washington, DC 20515 Now in our ninth year, the nationally and internationally recognized Jewish Electorate Institute (JEI), an independent, non-partisan, non-profit organization, continues to serve as the barometer for the Jewish electorate. We are therefore honored to submit the following Comments for the Record to the U.S. House of Representatives’ Judiciary Committee in support of its June 24, 2025, hearing on antisemitism - Rising Threat: America’s Battle Against Antisemitic Terror. This hearing, punctuated by the moving testimony of Matt Nosanchuk, reminded us that Jewish safety in America is not a political football - it is a national imperative. Nosanchuk, a former senior official in both the Obama and Biden Administrations and a lifelong advocate against antisemitism, laid bare the stark realities we face. The murder of Sarah Milgrim and Yaron Lischinsky, who were attending a Jewish community event just blocks from his home, brought the crisis home - literally and painfully. It also underscored a chilling truth: this could have been any one of us. Antisemitism today does not discriminate based on geography, profession, or even political identity. Nosanchuk rightly challenged both ends of the political spectrum. From the right, we've seen rising indulgence of white nationalist rhetoric, normalization of Nazi imagery, and an embrace of conspiracy theorists. When antisemitism is tolerated—or worse, weaponized—by public officials and influential institutions, it emboldens violence and undermines the rule of law. The example of the pardoning of the person wearing a “Camp Auschwitz” shirt at the riot on the Capitol on January 6, 2021, was not just shocking to the Jewish community – it was symptomatic of a deeper, corrosive tolerance for hate. From the left, antisemitism also too often masquerades as political critique. When Jews are asked to renounce their ties to Israel to participate in coalitions, or when pro-Palestinian activism turns violent against Jews, with intimidating targeted rhetoric and violence, that’s not solidarity – it’s exclusion and scapegoating. Our Jewish identity should never be a precondition for political participation. What we need is not partisan grandstanding, but comprehensive action. That includes implementing the Biden Administration’s well-thought-out National Strategy to Counter Antisemitism, restoring funding for civil rights enforcement at the Justice Department, and condemning hate, regardless of its ideological source. Nosanchuk’s call for education, prevention, and cross-community solidarity is exactly right. In closing, it’s our view at JEI that using antisemitism as cover for draconian immigration or university policies erodes the democratic institutions that have allowed Jewish life to flourish. Fighting hate must not become an excuse to violate civil liberties - ours or anyone else’s. Our safety as Jews has always been linked to the safety of others. In this perilous moment, we must demand more than soundbites. We must demand seriousness, solidarity, and above all, solutions. We are grateful to the Committee for having held this vital hearing at a perilous moment for American Jews. Sincerely, Barbara Goldberg Goldman Chairperson The Jewish Electorate Institute
