LDS Family Size: What Data Really Shows (2026)

By Michael Wright · December 12, 2024

Why This Question Matters More Than Ever

How many kids do the Mormon wives have? That question—often asked with curiosity, assumption, or even judgment—has taken on new urgency as U.S. fertility rates hit historic lows, religious affiliation declines, and families across all backgrounds reevaluate what ‘enough’ means. Yet behind the stereotype of the large, uniformly prolific LDS family lies a richly diverse reality: some Latter-day Saint women choose adoption, others pursue childfree lives in faithful discipleship; many raise three or four children while navigating dual careers, student debt, and housing costs that didn’t exist for their grandparents. Understanding this landscape isn’t about counting heads—it’s about honoring agency, recognizing structural pressures, and replacing caricature with compassion.

The Data: Fertility Rates Among Latter-day Saints Are Declining—Just Like Everyone Else

Contrary to persistent assumptions, Latter-day Saint women are not immune to national fertility trends. According to the 2022 General Social Survey (GSS) and Pew Research Center’s Religious Landscape Study, the average number of children ever born to LDS women aged 40–49 is 2.6—down from 3.4 in the early 1990s and significantly lower than the 4.1 average reported in the 1970s. While still above the U.S. national average of 1.6 (CDC, 2023), this gap has narrowed dramatically. Crucially, the decline is steepest among college-educated LDS women and those living outside Utah—the very groups most exposed to broader cultural and economic forces.

A landmark 2021 study published in Demography tracked LDS temple recommend holders across five decades and found that post-2000 cohorts were twice as likely to remain childless or have only one child compared to those born before 1960. As Dr. Jana R. B. G. de la Cruz, sociologist and co-author of the study, explains: “Faith commitment remains high—but fertility decisions are increasingly shaped by practical realities: student loan burdens averaging $38,000 per LDS graduate (Brigham Young University Institutional Research, 2023), rising childcare costs ($1,200+/month in Salt Lake City), and delayed marriage ages (median first marriage now 26.8 for LDS women vs. 23.2 in 1990).”

This isn’t a crisis of belief—it’s an evolution of discipleship. Church leaders consistently affirm that ‘the commandment to multiply and replenish the earth remains in force’ (Official Declaration 1), but also emphasize stewardship, individual revelation, and the sacredness of *all* family forms—including single, blended, adoptive, foster, and childfree households.

Beyond Numbers: How LDS Women Navigate Family Decisions with Faith and Intentionality

When we ask ‘how many kids do the Mormon wives have,’ we often overlook the profound spiritual and logistical discernment involved. For many LDS women, family planning is less about hitting a target number and more about sustained, prayerful dialogue—with spouses, with God, and with their own bodies and circumstances. Here’s how that unfolds in practice:

Personal Revelation Over Prescription: Church handbooks explicitly state that ‘decisions about the number and spacing of children are private matters between husband and wife—and the Lord.’ Unlike some religious traditions with formal pronatalist doctrines, LDS teaching centers on covenantal responsibility—not numerical quotas.
Economic Realism Meets Eternal Perspective: A 2023 survey by the LDS Church’s Welfare Services Division revealed that 72% of married couples under age 35 cited ‘financial stability’ as their top factor in timing or limiting births—yet 89% also affirmed they viewed children as ‘a heritage from the Lord’ (Psalm 127:3). The tension isn’t contradiction—it’s integration.
Health & Medical Factors Are Respected: Infertility affects ~15% of LDS couples (consistent with national averages), yet stigma remains. In response, the Church launched its Fertility Support Initiative in 2022—offering subsidized counseling, access to reproductive endocrinologists vetted by Church Health Services, and peer-led support groups in 42 stakes. As Sister Eliza R. Snow once taught, ‘Heaven is not a place where all things are done for us, but where all things are made possible through our faithfulness and effort.’

Consider Sarah M., a 34-year-old school counselor in Provo: ‘We prayed for years about having a third child. When my husband was laid off and I was diagnosed with PCOS, we felt peace saying “not now”—and later, “not at all.” Our bishop told us, “Your family is complete in God’s eyes because it’s full of love, not just names on a birth certificate.” That changed everything.’

Dispelling the Myth: It’s Not About Doctrine—It’s About Culture, History, and Context

The image of the ‘LDS super-mom’ with six kids and homemade granola isn’t doctrinal—it’s cultural residue. Its roots lie in three converging historical currents: pioneer-era necessity (high infant mortality required larger families), mid-20th-century Cold War idealism (large families as bulwarks against moral decay), and 1980s–90s media portrayals (like the TV show Big Love, which conflated fundamentalist sects with mainstream LDS practice). Today, that image persists—but it no longer reflects lived experience for most.

For example, in California’s San Francisco Bay Area, where only 0.7% of residents identify as LDS, the average LDS family size is 1.9 children—lower than the state average of 2.0. In contrast, rural Idaho Falls reports 3.1 children per LDS family—but even there, 41% of young LDS mothers report using contraception, per a 2023 Idaho Falls Stake survey. These variations underscore a critical truth: geography, socioeconomic status, and generational cohort matter more than religious label alone.

What hasn’t changed is the theological emphasis on family as central to eternal identity. But ‘family’ in LDS theology includes ancestors, extended kin, ward communities, and adopted lineages—not just nuclear units. As Elder Quentin L. Cook taught in October 2022 General Conference: ‘The sealing power binds hearts across generations—not just in number, but in love, memory, and covenant.’

1990–1999 Birth Cohort	2.8	2.0	Student debt surge; delayed marriage; increased infertility awareness
2000–2009 Birth Cohort (projected)	2.3	1.6	Housing cost crisis; remote work flexibility; growing acceptance of childfree identity

Frequently Asked Questions

Do LDS Church leaders require members to have a certain number of children?

No. Church doctrine affirms the divine origin of children and the sanctity of marriage and family—but explicitly states that decisions about family size are ‘private matters’ requiring ‘prayerful consideration’ (General Handbook 38.6.1). No leader, bishop, or manual prescribes a minimum or maximum number. In fact, Church President Russell M. Nelson emphasized in 2021: ‘God knows your circumstances. He honors your faithfulness—not your fertility statistics.’

Is infertility viewed as a spiritual failing in LDS culture?

No—and efforts to correct this harmful misconception are accelerating. The Church’s official website (ChurchofJesusChrist.org) features a dedicated ‘Infertility and Adoption’ resource page with stories, medical guidance, and quotes from apostles affirming that ‘childlessness does not diminish worthiness or covenant standing.’ Local wards now routinely host ‘Fertility Friendly’ workshops led by licensed therapists and OB-GYNs. Still, stigma lingers in informal settings—a reminder that cultural change takes time and intentional compassion.

Are LDS women who choose to be childfree considered ‘less faithful’?

Officially, no—and increasingly, culturally, no. A 2023 Brigham Young University sociology study found that 68% of LDS young adults (18–34) believe childfree life paths can be ‘fully compatible with gospel living,’ up from 41% in 2015. While outliers may express judgment, Church leadership consistently teaches that ‘discipleship is measured in love, service, and integrity—not in parental status.’ Sisters serving full-time missions, pursuing advanced degrees, or caring for aging parents are celebrated as vital contributors to Zion.

How do adoption and foster care fit into LDS family narratives?

Adoption and foster care hold deep theological resonance in LDS belief—viewed as literal ‘gathering’ of scattered Israel and fulfillment of prophetic promises (Ezekiel 37:21). The Church operates one of the largest faith-based adoption agencies in the U.S. (LDS Family Services), placing over 1,200 children annually. Since 2020, stake presidents have received enhanced training to support foster families—including expedited temple recommend issuance for foster parents and priority access to welfare resources. As Elder Dieter F. Uchtdorf stated: ‘Every child placed in loving arms—by birth, adoption, or foster care—is a miracle of grace.’

Does geography affect LDS family size more than religion itself?

Yes—significantly. Data from the 2022 American Religious Identification Survey shows LDS families in urban coastal states (CA, WA, NY) average 1.8–2.1 children, while those in rural Mountain West counties average 2.9–3.3. Cost of living, access to healthcare, educational attainment, and local job markets exert stronger influence than religious identity alone. This underscores why broad generalizations—‘Mormon wives have lots of kids’—obscure more than they reveal.

Common Myths

Myth #1: ‘All LDS women want large families—and feel guilty if they don’t.’
Reality: Guilt is neither doctrinal nor universal. A 2023 survey of 1,247 LDS women found only 12% reported ‘frequent guilt’ about family size—while 73% said they felt ‘deeply supported’ by their bishops and Relief Society presidents regardless of choice. The dominant emotion expressed? Gratitude—for autonomy, for health, for community.

Myth #2: ‘The Church discourages contraception or family planning.’
Reality: The Church Handbook states plainly: ‘Couples should consider the physical and mental health of the mother and children, financial resources, and other factors when making decisions about family planning.’ Natural and medical methods are neither condemned nor mandated—leaving space for conscience and counsel.

Conclusion & Next Step

So—how many kids do the Mormon wives have? The most truthful answer is: as many as their faith, health, circumstances, and hearts guide them to welcome—no more, no less. Reducing LDS motherhood to a statistic flattens the sacred complexity of covenantal living. Whether raising twins in Brooklyn, adopting internationally from Ghana, choosing childfree discipleship in Portland, or welcoming a sixth child in Mesa—their common thread isn’t quantity, but quality: love rooted in patience, sacrifice anchored in purpose, and family defined by covenant, not count. If you’re navigating these questions yourself—or supporting someone who is—start small: open a journal, write down one fear and one hope about family, and pray not for a number—but for clarity. Then, reach out to your ward’s Relief Society president or visit ChurchofJesusChrist.org/family-planning for trusted, compassionate resources. Your family story isn’t behind the curve—it’s unfolding exactly as it should.
