Where It All Began
The roots of the largest families in the US trace back to the Mormon pioneers of the 19th century, whose practice of plural marriage—officially abandoned by the LDS Church in 1890 but lingering in some communities—created multi-generational kinship networks that persisted long after the doctrine was banned. Families like the Buhmans, the Allreds, and the Moon clans in Utah are direct descendants of these early settlers, their large broods a mix of religious devotion and practical survival. But the story doesn’t end with Utah. In the early 20th century, Italian and Mexican immigrant communities in cities like New York and Los Angeles also embraced extended-family living as a way to navigate an unfamiliar land. Grandparents moved in with adult children to share housing costs, while aunts, uncles, and cousins pooled resources to build businesses or buy property. These weren’t just families; they were economic units, a buffer against the instability of the Great Depression and the industrial age.The Early Signs
By the 1950s, the American nuclear family—the two parents, two kids, white picket fence ideal—had become the dominant model, pushed by post-war prosperity and suburban expansion. Large families began to fade from mainstream visibility, relegated to rural areas or immigrant enclaves. Yet even then, pockets of resistance remained. In the Appalachian South, for example, families of 10 or more were common, their size a product of both tradition and the need for labor on farms and in small-town businesses. Meanwhile, in Hawaii, the blending of Polynesian, Asian, and European lineages created a cultural norm where extended families lived together, a practice that continues today. These early signs of resilience foreshadowed the modern revival of large families—not as a relic of the past, but as a deliberate choice in response to contemporary challenges.The Turning Point
The real shift began in the late 1990s and early 2000s, when two forces collided: the economic precarity of the post-dot-com crash and the cultural realignment of millennials. The Great Recession of 2008 accelerated the trend, as young adults—facing stagnant wages, crippling student debt, and a housing market that priced them out of homeownership—turned to their parents for help. Suddenly, multi-generational living wasn’t just a rural tradition or an immigrant necessity; it was a survival strategy for the middle class. The data supports this. Between 2010 and 2020, the number of three-generation households in the US grew by 40%, with the fastest increases in states like California, Texas, and Florida—areas where housing costs and job instability made independent living unaffordable. Families that once would have been seen as outliers became, in some circles, the new normal."We didn’t choose to live like this. The economy forced our hand." — Maria Rodriguez, 54, whose household of 12 in Miami includes three generations of her family.
The Build-Up, Year by Year
| Period | Key Developments |
|---|---|
| 1990–2000 | Rise of shared housing among immigrant communities; first signs of millennial cohabitation with parents due to student debt. |
| 2001–2010 | Post-9/11 economic uncertainty leads to increased multi-generational moves; Utah’s Buhman family gains national attention. |
| 2011–2020 | Great Recession normalizes large households; census data shows 30%+ growth in three-gen families. |
| 2021–Present | Pandemic accelerates trend; remote work allows families to live together without sacrificing careers; housing shortages push demand higher. |
Lessons From the Journey
- Economics over tradition: Most modern large families aren’t driven by religion or culture alone—they’re a financial calculation.
- Space is the new luxury: From Utah’s 10-bedroom homes to California’s converted garages, housing adaptations reflect creative problem-solving.
- Interdependence is rising: In an era of declining social safety nets, families are filling the gaps that government once provided.
- Privacy redefined: Large families require new social contracts—how to balance personal space with collective living.
Where Things Stand Today
Today, the largest families in the US are a microcosm of broader societal trends. In Utah, clans like the Buhmans continue to grow, their numbers a testament to both faith and resource-sharing efficiency. Meanwhile, in urban centers, blended families—where step-parents, ex-spouses, and in-laws live under one roof—are redefining what constitutes a household. The pandemic only sped this up; with remote work now common, the logistical barriers to multi-generational living have eroded. Yet challenges remain. Zoning laws in many states still favor single-family homes, making it difficult for large families to find suitable housing. School districts often struggle to accommodate the needs of multi-age groups. And culturally, there’s still a stigma—the assumption that large families are either wealthy or struggling, when in reality, they’re often both.
Conclusion
The largest families in the US are more than a demographic footnote; they’re a living argument about the future of American society. As housing costs rise, wages stagnate, and social support systems weaken, these families offer a model of resilience through unity. They prove that size isn’t just about numbers—it’s about how people choose to live, to support one another, and to adapt when the world pushes back. The question isn’t whether these families will persist—it’s how the rest of America will respond. Will they be seen as relics of the past, or as a blueprint for the future?Comprehensive FAQs
Q: What’s the largest family in the US by verified count?
A: The Buhman family of Utah holds the record with 69 children across three generations, though some clans in Mexico and Italy have unverified claims of 70+ members. Most large families in the US today hover between 10 and 25 people.
Q: Are most large families religious?
A: Historically, yes—many trace back to Mormon or Catholic traditions. Today, however, economic necessity is the primary driver, with secular families in urban areas adopting multi-generational living for financial reasons.
Q: Do large families receive government assistance?
A: Some do, but policies vary. Section 8 housing and child tax credits can help, though many families avoid assistance due to stigma or bureaucratic hurdles. Utah’s Buhman family, for instance, has rejected welfare, relying instead on private donations and communal support.
Q: How do large families handle privacy?
A: Strategies vary. Some families redraw floor plans to create private spaces, while others use shifted schedules (e.g., grandparents sleeping during the day). Open communication is key—many report that shared values outweigh the need for solitude.
Q: Are large families growing or shrinking?
A: The trend is stable but evolving. While Utah’s megaclans remain static, urban multi-generational households are expanding rapidly, driven by cost-of-living crises. Experts predict this model will only gain traction as housing becomes less affordable.
Q: What’s the biggest challenge for large families?
A: Housing accessibility tops the list. Many families struggle to find homes with enough bedrooms, bathrooms, and parking. School enrollment and healthcare coordination are also major hurdles, as systems aren’t designed for households with 15+ members.
Q: Can large families thrive long-term?
A: Absolutely—but it requires intentional planning. Successful families often pool incomes, share childcare, and negotiate roles (e.g., one parent handling finances, another managing household logistics). The key is flexibility; rigidity leads to conflict.
