Understanding the Difference Between Religious and Ethnic Judaism
When asking the question, “How many ethnic Jews are there?” it’s vital to first distinguish between religious and ethnic identity. Many people conflate being Jewish with practicing Judaism, the monotheistic religion rooted in the Torah. However, being ethnically Jewish extends beyond religious practice—it encompasses ancestry, heritage, cultural traditions, and historical identity.
Ethnic Jews are individuals who identify as part of the Jewish people through lineage, regardless of whether they actively practice the Jewish faith. This category includes secular Jews, cultural Jews, and those who may not identify as religious but trace their roots back to Jewish communities. In contrast, religious Jews are those who observe Jewish rituals, holidays, and laws, such as keeping kosher, attending synagogue, and observing Shabbat.
The distinction is crucial because population estimates vary dramatically depending on how “Jewish” is defined. For example, Israel’s Central Bureau of Statistics counts anyone with at least one Jewish grandparent or who has converted under Orthodox auspices as a Jew for aliyah (immigration) purposes. Meanwhile, demographic studies in the U.S. often rely on self-identification in surveys.
Global Jewish Population Estimates: The Numbers Behind the Data
Precise numbers on the global Jewish population remain challenging due to differing methodologies, migration patterns, intermarriage rates, and the complex nature of identity. However, reliable sources such as the World Jewish Population Survey (published annually by the Berman Jewish DataBank), the Pew Research Center, and national statistics offer the most current and comprehensive estimates.
As of 2024, the estimated number of ethnically Jewish people worldwide stands at approximately 15.7 million. This figure includes individuals who identify as Jewish by ancestry, ethnicity, or religion, regardless of their level of religious observance.
This global count represents roughly 0.2% of the world’s total population, reflecting a community that has endured diaspora, persecution, and assimilation, yet has sustained a distinct cultural and ethnic identity for millennia.
Regional Distribution of the Jewish Population
Jewish communities are geographically dispersed, but the majority of the world’s Jews live in just two countries: Israel and the United States.
- Israel – ~7.2 million ethnic Jews
- United States – ~5.7 million ethnic Jews
- France – ~450,000
- Canada – ~400,000
- United Kingdom – ~280,000
- Argentina – ~170,000
- Russia – ~150,000
Israel hosts the world’s largest Jewish population, a significant milestone since its founding in 1948 as a Jewish homeland. This demographic shift means, for the first time in nearly 2,000 years, the majority of the world’s Jews live in the Land of Israel.
In contrast, many historically significant Jewish communities outside Israel and the U.S. are shrinking due to assimilation, emigration, or low birth rates—particularly in Western Europe, the former Soviet Union, and Latin America.
Israel: The Center of Jewish Demographic Growth
Israel’s Jewish population growth is notable not only in absolute numbers but in its impact on global Jewish demographics. With a current population of around 9.6 million, Jews constitute about 74% of Israel’s total population.
Israel’s high fertility rates among religious and ultra-Orthodox (Haredi) Jewish communities are a key driver of population growth. The Haredi population, in particular, has experienced a doubling over the past two decades and is projected to constitute one-quarter of Israel’s school-age population by 2050.
Moreover, Israel continues to attract Jews from around the world through the Law of Return, which grants Jews and their descendants the right to immigrate and become citizens. This policy has led to continuous population growth via aliyah, especially from France, Russia, the United States, and Ethiopia.
United States: A Diverse and Evolving Jewish Community
The U.S. maintains the second-largest Jewish population, though precise numbers are subject to debate due to different definitions and inclusion criteria. Estimates range from 5.7 to 7.5 million when including people with partial Jewish identity or patrilineal descent.
American Jews are highly diverse, with significant differences in religious affiliation:
- Reform Judaism (35%)
- Conservative Judaism (18%)
- Orthodox Judaism (9%)
- Just as Jewish (no denomination, 30%)
- Secular or cultural Jews (growing segment)
A hallmark of American Jewry is its relatively high rate of intermarriage—approximately 60% of non-Orthodox Jews marry outside the faith. This has sparked concern about long-term demographic continuity and prompted community investment in outreach and education.
Geographically, U.S. Jews are concentrated in major metropolitan areas: New York (especially Brooklyn and Manhattan), Los Angeles, Miami, Chicago, and the San Francisco Bay Area. The New York metropolitan region alone is home to over 2 million Jews, making it one of the largest Jewish communities in the world.
Defining Ethnic Jewishness: Who Counts as a Jew?
One of the biggest challenges in estimating the number of ethnic Jews is the lack of a universal definition. Different cultures, religious movements, and nations interpret Jewish identity in distinct ways.
Halachic (Traditional Jewish Law) Definition
According to Halacha, Jewish law, a person is Jewish if they are born to a Jewish mother or have undergone a valid conversion (giyur) under Orthodox auspices. This matrilineal descent rule has been upheld for centuries and remains central in Orthodox and Conservative Jewish communities.
However, this standard excludes individuals with only a Jewish father—a significant issue in interfaith families. Reform Judaism in the U.S. and elsewhere recognizes patrilineal descent under certain conditions, broadening the definition in those movements.
Secular and Cultural Jewish Identity
For many, Jewish identity is not defined by religious observance but by cultural heritage, language, food, history, and family traditions. These individuals may not attend synagogue or believe in God, but still feel a strong connection to Jewish peoplehood.
In countries like the U.S. and Canada, sociologists often use the term “ethnic or cultural Jews” for people who do not practice Judaism but identify Jewishly through ancestry, celebrate Jewish holidays in cultural contexts, or partake in Jewish organizations.
This broader conception inflates population counts. For example, the Pew Research Center’s 2020 study of U.S. Jews estimated 5.8 million adults identify as Jewish by religion, but that number increases to 7.5 million when including those who say they have Jewish ancestry or background but do not identify as Jewish by religion.
The Challenge of Self-Identification
Modern demographic studies often rely on self-identification due to the impracticality of verifying ancestry or religious status. In national censuses or opinion polls, respondents are asked whether they consider themselves Jewish. This method captures people who feel ethnically tied to Judaism even if not halachically Jewish.
While self-identification allows for a more inclusive count, it also introduces fluidity. A person might say “yes” to being Jewish in a cultural context but “no” in a religious survey. This complexity complicates cross-national comparisons and long-term demographic analysis.
Jewish Subgroups: Diversity Within the Ethnic Community
The Jewish people are not a monolithic group. They comprise various ethnic and cultural subgroups shaped by centuries of diaspora, migration, and local influence.
Ashkenazi Jews
Ashkenazi Jews originate from Central and Eastern Europe—Germany, Poland, Ukraine, Russia, and beyond. They constitute the largest Jewish ethnic group globally, making up roughly 70–80% of the world’s Jewish population.
Historically, Ashkenazi Jews developed unique religious customs, liturgical music, and the Yiddish language. Tragically, two-thirds of the 9 million Jews in Europe before WWII were Ashkenazi, and approximately 6 million perished in the Holocaust. Today, most Ashkenazi Jews live in Israel, the United States, and Canada.
Sephardic Jews
Sephardic Jews trace their roots to the Iberian Peninsula (Spain and Portugal). After their expulsion in 1492, many resettled in the Ottoman Empire, North Africa, the Balkans, and the Middle East. They developed distinct traditions, liturgy, and languages such as Ladino (Judeo-Spanish).
While smaller in number than Ashkenazi Jews, Sephardic communities have a rich cultural legacy and are now integrated into modern Israel, France, Turkey, and Latin America.
Mizrahi Jews
Mizrahi (Eastern) Jews originate from Muslim-majority countries across the Middle East and North Africa—such as Iraq, Iran, Yemen, Syria, and Morocco. Their traditions differ significantly from European Jewry, reflecting centuries of integration within Arabic and Persian cultures.
After the establishment of Israel, over 800,000 Mizrahi Jews were displaced or fled from Arab countries due to rising antisemitism and political instability. Today, their descendants form a large segment of Israel’s population and have revitalized Middle Eastern Jewish music, cuisine, and religious practices.
Other Jewish Communities
Beyond these major groups, smaller but significant communities include:
- Ethiopian Jews (Beta Israel)
- Bukharan Jews (Central Asia)
- Cochin Jews (India)
- Chinese Jews (Kaifeng, historically)
- African-American Jews (some converts, some claim ancient descent)
These communities demonstrate the geographic and cultural diversity of Jewish ethnic identity across centuries.
Demographic Trends Shaping the Jewish Population
Jewish demographic patterns are influenced by a range of factors, including birth rates, intermarriage, migration, and antisemitism. Understanding these trends is essential for predicting future population trajectories.
Fertility and Population Growth
Fertility rates vary widely among Jewish communities:
- In Israel, the average Jewish woman has 3.1 children—much higher than in Western nations.
- Among ultra-Orthodox Jews in both Israel and the U.S., fertility can exceed 6–7 children per family.
- In contrast, secular Jewish communities in Europe often have below-replacement fertility (below 2.1 children per woman).
This disparity means that within Israel, the Orthodox population is growing rapidly and will have increasing societal and political influence. Globally, high fertility rates help offset population losses elsewhere.
Intermarriage and Its Impact
Intermarriage—marrying a non-Jewish partner—is a significant factor in diaspora communities. In the U.S., the rate of intermarriage has risen steadily since the 1970s. The 2020 Pew study found that 72% of non-Orthodox Jews marry someone who is not Jewish.
While intermarriage can lead to assimilation, many interfaith families still raise children with Jewish identities. In response, organizations like Hillel and Chabad have expanded programs to engage these families.
Israel maintains a much lower intermarriage rate due to the homogeneity of its Jewish population and strong cultural cohesion.
Migration and Return to Israel
Aliyah (immigration to Israel) continues to shape Jewish demographics. In recent years, waves of immigration have come from:
- France (driven by rising antisemitism)
- Russia and Ukraine (due to war and instability)
- North America (both religious and secular motivations)
In 2023 alone, over 32,000 people made aliyah, the highest rate in decades. These migrations contribute to Israel’s growing dominance in the global Jewish demographic landscape.
Antisemitism and Emigration
In Europe, growing concerns over security, antisemitism, and integration have prompted Jewish emigration—particularly from France, Belgium, and Sweden. At the same time, Jewish communities in Germany have grown due to immigration from the former Soviet Union, though many younger Jews are now leaving due to rising hate crimes.
In North America, while antisemitism remains a concern—especially after the October 2023 Hamas attack on Israel and the subsequent war in Gaza—most Jewish communities continue to feel relatively safe. Still, acts of vandalism, harassment, and hate speech are on the rise in some areas.
Challenges in Counting Ethnic Jews Accurately
Despite advances in survey methodology, accurately counting ethnic Jews remains fraught with difficulty. Several key challenges include:
Lack of Universal Criteria
No single entity governs Jewish identity globally. The State of Israel, Orthodox rabbis, Reform movements, academics, and national governments all use different standards. This leads to inconsistencies in who is counted.
Hidden or Unidentified Jews
In some countries, historical persecution has led to families concealing their Jewish identity across generations. For example, “anusim” (forced converts, primarily in Spain and Portugal) or crypto-Jews in Latin America may only rediscover their heritage decades later.
Similarly, in the former Soviet Union, official atheism and systemic antisemitism led many to hide or abandon their Jewish identity. Though some have reclaimed it post-1991, many still do not identify as Jewish due to cultural erasure or fear.
Assimilation and Loss of Identity
In multicultural societies, younger generations may lose connection with Jewish traditions, especially in intermarried families. Without active engagement in community life, these individuals may not identify as Jewish in surveys—erasing them from demographic counts despite their ancestry.
The Future of the Global Jewish Population
Looking ahead, the global Jewish population is likely to remain stable or grow slightly, but with major regional shifts.
Continued Growth in Israel
Israel is expected to surpass 9 million Jews by 2030 and could host over half of the world’s Jewish population within the next two decades. Its vibrant society, strong family culture, and immigration policies will sustain growth.
Stagnation or Decline in Diaspora Communities
In Western Europe and parts of North America, Jewish populations are projected to decline or remain flat due to aging populations, intermarriage, and low birth rates. Without renewed efforts in education and community engagement, some diaspora communities may shrink significantly.
The Role of Technology and DNA Testing
Advances in genealogy and DNA testing (e.g., 23andMe, Ancestry.com) have enabled individuals to discover unexpected Jewish ancestry. Many people with Sephardic or Ashkenazi markers are now connecting with communities or converting formally. These trends may influence future definitions and counts of ethnic Jews.
Conclusion: An Enduring Identity with a Complex Count
So, how many ethnic Jews are there? While the most reliable estimate is around 15.7 million, this number is fluid and depends heavily on how one defines Jewishness—by religion, ancestry, culture, or self-identification.
The Jewish people represent a unique case study in global demography: a small ethnic group with an outsized cultural, historical, and religious influence. From ancient roots in the Levant to modern life in Tel Aviv, New York, and Paris, the Jewish community continues to evolve and adapt.
Despite challenges—assimilation, antisemitism, and identity debates—Jewish ethnic identity remains resilient. Whether counted by religious law, national censuses, or personal belief, the story of the Jewish people is one of continuity, diversity, and enduring connection across time and space.
What is the estimated global population of ethnic Jews?
The estimated global population of ethnic Jews is approximately 15.2 million people as of recent demographic studies. This number includes individuals who identify as Jewish through ancestry, heritage, or cultural background, regardless of religious practice. The majority of this population is concentrated in two main regions: the United States, home to about 5.7 million ethnic Jews, and Israel, with around 7 million Jewish residents, making these two countries the largest Jewish communities in the world.
Other significant populations are found in countries like France, Canada, the United Kingdom, Argentina, and Russia, each hosting more than 100,000 ethnic Jews. These figures are based on national censuses, community surveys, and data from Jewish organizations, but accurate counts can be challenging due to varying definitions of Jewish identity and self-identification practices. Factors such as secularism, intermarriage, and migration also influence population estimates, necessitating ongoing research and updated methodologies to maintain demographic accuracy.
How is Jewish identity defined—ethnically, religiously, or culturally?
Jewish identity is multifaceted, encompassing ethnic, religious, and cultural dimensions. Ethnically, a person may be considered Jewish if they are born to a Jewish parent, particularly according to traditional matrilineal descent in Orthodox Judaism. However, Reform and other progressive Jewish movements often recognize patrilineal descent if the individual is raised with a Jewish identity. This ethnic component is rooted in shared ancestry, history, and communal heritage, distinct from religious observance.
Religiously, being Jewish involves adherence to Judaism, including belief in its principles and engagement in rituals and practices. Yet, many people who identify as ethnically Jewish do not practice the religion or may even identify as atheist or agnostic. Culturally, Jewish identity can include language (such as Yiddish or Hebrew), cuisine, literature, music, and participation in communal traditions. These overlapping interpretations mean that Jewish identity is not monolithic and varies significantly across individuals and communities.
Which countries have the largest Jewish populations?
Israel and the United States are home to the two largest Jewish populations in the world. Israel, established as a Jewish state in 1948, has approximately 7 million Jewish residents, representing about 73% of its total population. The country serves as a center of Jewish religious, cultural, and political life, attracting immigrants through its Law of Return, which grants citizenship to Jews and their descendants from anywhere in the world.
The United States hosts the second-largest Jewish population, with about 5.7 million people identifying as ethnically or religiously Jewish. Major Jewish communities are located in cities such as New York, Los Angeles, and Miami. Other countries with substantial Jewish populations include France (around 450,000), Canada (approximately 400,000), and the United Kingdom (about 280,000). These communities vary in their levels of religious observance, cultural preservation, and integration into broader society.
How has the Jewish population changed over time?
The global Jewish population has undergone significant changes over the past century, shaped by events such as the Holocaust, mass migrations, and shifting geopolitical landscapes. Before World War II, an estimated 16.6 million Jews lived worldwide, but the Holocaust led to the murder of six million European Jews, drastically reducing the population. Following the war, large-scale immigration to Israel and the Americas helped rebuild communities and stabilize numbers.
Since the mid-20th century, the Jewish population has gradually recovered, but growth rates have remained slow due to low birth rates, assimilation, and intermarriage, particularly in diaspora communities outside Israel. Israel has experienced steady growth, fueled by Jewish immigration (aliyah), high birth rates among certain groups like the Haredim (ultra-Orthodox), and government policies supporting family life. Meanwhile, diaspora populations in Europe and North America have seen relative stability or slight decline, prompting concerns about long-term demographic sustainability.
What challenges exist in accurately counting the Jewish population?
Accurately counting the Jewish population presents several challenges due to the fluid and multidimensional nature of Jewish identity. Unlike many religious or ethnic groups, there is no universally accepted criterion for who counts as Jewish—some define it matrilineally, others bilineally, and still others by personal identification regardless of ancestry. This lack of standardization complicates census data and survey results, especially in countries where religion and ethnicity are not officially recorded.
Additionally, many Jews live in secular or mixed households and may not openly identify as Jewish in official surveys due to fear of discrimination, lack of affiliation, or personal choice. Interfaith marriages, conversions, and variations in religious practice further blur demographic boundaries. Organizations such as the Jewish People Policy Institute and local Jewish federations rely on sampling, community registries, and statistical modeling to estimate populations, but these methods are inherently imprecise and require constant refinement.
How does intermarriage affect Jewish population statistics?
Intermarriage—the marriage between a Jewish individual and someone of another faith or ethnic background—has a significant impact on Jewish population statistics, particularly in diaspora communities. In countries like the United States, intermarriage rates among non-Orthodox Jews have exceeded 50% in recent decades, raising concerns about long-term demographic continuity. Children from interfaith unions are less likely to be raised with a strong Jewish identity unless active efforts are made by the family or community to engage them.
However, the effect of intermarriage is complex and not uniformly negative. Some intermarried couples raise their children as Jews, and many communities offer outreach programs to include interfaith families. Reform and other progressive movements have responded by embracing inclusivity, recognizing patrilineal descent and conversion alternatives. While intermarriage can lead to assimilation and population decline in some contexts, it also presents opportunities for renewal and expansion of Jewish identity when coupled with education and integration efforts.
What role does Israel play in the global Jewish population?
Israel plays a central role in the global Jewish population as both a demographic anchor and a symbolic homeland. With around 7 million Jewish residents, it is home to the largest concentration of Jews worldwide and the only country where Jews constitute a majority. The Law of Return allows Jews from any country to immigrate and gain citizenship, reinforcing Israel’s function as a refuge and national center for the Jewish people.
Beyond numbers, Israel influences Jewish identity globally through its cultural, religious, and political institutions. Hebrew language revitalization, religious education, and national celebrations like Yom Ha’atzmaut (Independence Day) help strengthen Jewish connection worldwide. Israel also serves as a destination for diaspora Jews through programs like Birthright, encouraging engagement with heritage. Its existence and policies significantly shape how Jews around the world perceive their identity, security, and future.
