The Great Downsize, Part 2: The Decline of American Jewish Organizations

The great downsize, which has been documented since the 1990’s, reflects the undoing of civic and religious engagement but raises a broader challenge to American democracy itself. Earlier on these pages, we noted the financial challenges facing institutions; here we are examining the declining membership numbers.

Civic organizations: Membership and active participation in groups like labor unions, fraternal organizations, neighborhood associations, PTAs, and service clubs have declined overall. This trend was famously documented by Robert D. Putnam in Bowling Alone.

Political parties: Formal party identification remains strong, and political engagement online is very high, but fewer people participate in local party organizations or long-term grassroots civic structures than in earlier decades. At the same time, political polarization and issue activism have increased.

Religious institutions: Religious affiliation and attendance have declined significantly. A growing share of Americans identify as religiously unaffiliated (“nones”), while weekly church attendance and membership in churches, synagogues, and similar institutions have generally fallen. Gallup found that membership in houses of worship fell below 50% of American adults for the first time in modern polling history.

The overall pattern suggests less participation in long-standing formal institutions but more fluid, individualized, and digital forms of engagement. One major debate among sociologists and political scientists is whether this represents a true decline in “social capital” or simply a transformation in how Americans connect and organize.

On the Jewish Side:

Traditional forms of Jewish institutional participation (synagogue membership, attendance, denominational affiliation, supplementary religious schooling, and membership-based organizations) have declined over the last several decades. At the same time, the story is more nuanced than a simple collapse. Some sectors of Jewish life are growing, and many Jews remain strongly connected to their Jewish identity outside traditional institutional engagement.

Synagogue Attendance and Membership:

The most comprehensive source is the 2020 survey of American Jews by the Pew Research Center.

Pew found that only about 20% of American Jews attend synagogue services at least monthly. Roughly half say they seldom or never attend religious services. Among Jews of no religion, attendance is extremely low. The largest non-Orthodox denominations have experienced long-term decreases in affiliation and participation.

Other indicators point in the same direction. Supplementary Hebrew-school enrollment declined by about 45% between 2006 and 2020, while over a quarter of such schools closed. Researchers and communal leaders have linked this decline to broader decreases in synagogue affiliation.

One of the most striking patterns is the weakening of denominational identity. Pew found that the Conservative movement has experienced substantial net losses over time. Reform Judaism has generally maintained or modestly increased its share of Jews despite broader secularization. However, a growing share of Jews identify with no denomination at all. This suggests that many Jews who remain Jewish are choosing less formal or less institutionally committed forms of identification.

Jewish organizations have also been affected by the wider American trend away from membership institutions, as referenced above. Major Jewish membership organizations are all experiencing this phenomenon as their peak mid-20^th century numbers have declined.  Across the United States, participation in churches, synagogues, mosques, civic organizations, fraternal groups, and voluntary associations has declined for decades, struggling to attract younger generations.

How people engage has changed. Today, many are more likely to donate, attend events, volunteer for causes, or participate online without becoming traditional members. As noted in my prior work, Jewish institutions operate within that broader social environment.

Are There Exceptions?

The most important finding from recent Jewish demographic research is that decline is not universal. By every measure American Orthodoxy is continuing to grow.

Indeed, while non-Orthodox sectors face aging memberships and weaker institutional attachment, Orthodox communities have generally expanded both numerically and institutionally.

Pew found many Jews who rarely attend synagogue still are celebrating Jewish holidays, enjoying traditional Jewish foods, participating in Jewish cultural activities, and are feeling connected to Jewish history and peoplehood. In other words, institutional participation may be declining faster than Jewish identity itself.

Several Jewish organizations have reported increased participation following the October 7, 2023 attacks in Israel and the subsequent rise in antisemitic incidents. There is evidence that such institutions as Hillel International and Birthright Israel, among others, are attracting significant numbers. Reports describe increased attendance at Jewish events, greater interest in learning, and renewed communal engagement, especially among younger Jews seeking connection and solidarity. The long-term durability of this trend remains uncertain.

Researchers generally identify several overlapping causes. Secularization represents the single most common explanation given by Jews who do not attend synagogue as they do not consider themselves religious. Pew found the top reasons for infrequent attendance were:

• “I’m not religious.”
• “I’m just not interested.”
• “I express my Jewishness in other ways.”

This parallels trends across many religious traditions in North America and Europe. Many Jews increasingly define Jewishness today as ethnic, cultural, historical and familial. As we have noted elsewhere on these pages, alternative forms of informal organizing models are rapidly emerging.

The Generational Factor:

Younger adults generally show less enthusiasm for joining formal membership organizations of all kinds. The broader shift away from civic associations, religious institutions, and dues-based organizations has affected Jewish institutions as well.

Intermarriage rates have risen substantially among non-Orthodox Jews. Researchers debate the consequences, but many argue that intermarriage can weaken the likelihood that children will be raised with strong institutional Jewish involvement unless communities actively engage mixed families.

Some scholars and rabbis have argued that synagogue dues, religious-school costs, and expectations of participation discourage involvement. Interestingly, Pew found cost was not the most common reason cited by non-attenders; lack of religiosity and lack of interest were much more frequently mentioned. Still, financial barriers remain a concern in many communal discussions.

Many scholars therefore describe the trend not as “less Jewishness,” but as a shift from membership-based institutional Judaism toward more individualized, cultural, networked, and privatized forms of Jewish engagement. Accordingly, the rise of virtual Judaism has also contributed to this shift involving on-line Jewish experiences.

The Broader Meaning:

Not only do these trends impact the health and vitality of the civic, religious and communal sector but such downsizing profoundly impacts the quality, vitality and health of America’s sense of the common good, as fewer individuals are bound together around shared activities and common purpose toward preserving democratic institutions, civic values and religious communalism.
