Fact check: What is the correlation between body count and divorce rates in the United States as of 2025?
Executive Summary
Research through 2025 shows no simple, population-level “body count” metric that reliably predicts U.S. divorce rates; divorce has declined slowly over recent decades while some studies link higher numbers of premarital sexual partners to elevated divorce risk for individuals, particularly at extreme counts. National divorce statistics from 2022–2024 indicate falling crude and refined divorce rates and substantial geographic and demographic variation, while social-science work flags correlation (not proven causation) between large numbers of premarital partners and later marital instability in some samples [1] [2] [3] [4]. Competing interpretations exist: some commentators and institutes emphasize individual-level associations, others stress confounding factors—age at marriage, socioeconomic status, mental health, and selection effects—meaning the public debate often amplifies correlations into causal claims without consistent empirical support [5] [6] [7].
1. Why headline divorce numbers don’t settle the “body count” question
National divorce indicators show declining divorce rates across the U.S. while absolute divorce events remain substantial; for example, refined divorce rates reported near 14.2–14.4 divorces per 1,000 married women in 2023–2024 and a crude rate around 2.4 per 1,000 people earlier in the decade, with roughly 1.8 million divorces in 2023 reported by major research centers [1] [2] [3]. Those aggregate statistics are useful for tracking population-level marriage stability but they say nothing about how an individual’s number of prior sexual partners—often termed “body count”—affects their personal divorce risk. Population trends and individual risk factors operate on different levels, and conflating the two creates misleading headlines. Geographic differences further complicate interpretation because state-level cultures and laws influence divorce independent of sexual history patterns [3].
2. What social science actually finds about sexual history and divorce
Peer-reviewed and institute-level studies report associations between higher counts of premarital partners and greater divorce risk in some datasets, with one line of work finding that individuals reporting nine or more premarital partners face notably higher divorce rates compared with those reporting fewer partners [4]. These studies typically control for some confounders but cannot fully eliminate selection effects: people who accumulate many partners may differ systematically in traits—personality, socioeconomic background, attitudes toward commitment—that also predict divorce. Several recent commentaries and literature reviews emphasize the difference between correlation and causation, cautioning that the observed relationship may reflect broader life-course patterns rather than a direct causal effect of sexual history on marital stability [6] [7].
3. Why some sources amplify the link and what agendas to watch for
Certain outlets and think tanks present stronger claims that women with higher partner counts are “bad wives” or inherently more likely to divorce; these narratives often simplify complex findings and underplay confounders [5]. Such framing can reflect ideological agendas or cultural perspectives about sexuality and gender. Conversely, academic researchers tend to present nuanced results that highlight methodological limitations and contextual moderators—age at marriage, education, religiosity, and mental health—that strongly influence both sexual behavior and marital outcomes. Readers should treat sensational headlines skeptically and prioritize studies that report effect sizes, control variables, and robustness checks [5] [6] [7].
4. What the evidence omits and why that matters for policy and personal decisions
Existing work often omits long-term mediators like relationship quality, cohabitation history, and economic stability, which can fully or partly account for observed associations between premarital partner count and divorce. Many studies rely on retrospective self-reports or specific subpopulations, limiting generalizability; others measure partner counts without distinguishing context—consensual casual encounters versus serial cohabiting relationships—making it hard to draw actionable conclusions for couples or policymakers [8] [7]. Without consistent measurement standards and longitudinal designs that track individuals from before sexual debut into marriage, causal inference remains weak, and policy prescriptions based on “body count” risk stigmatizing behavior rather than addressing root drivers of marital instability [6].
5. Bottom line for journalists, couples, and policymakers
The best-supported conclusion is that higher numbers of premarital partners correlate with greater divorce risk in some studies but do not establish a direct causal pathway that applies uniformly across the population; meanwhile, U.S. divorce rates have generally declined into the early 2020s, reflecting complex demographic shifts rather than changes in any single behavioral metric [1] [2] [4]. Responsible reporting and policy should focus on well-established drivers of marital outcomes—economic security, mental health, educational attainment, and relationship skills—while acknowledging individual-level variability and avoiding moralizing headlines that overstate the predictive power of “body count” [3] [6].
