    "description": "The \"50% of marriages end in divorce\" claim is one of the most durable statistical myths in American culture. It has been repeated so often — in news articles, self-help books, wedding speeches, and casual conversation — that most adults treat it as settled fact. The figure was never a cohort estimate; it came from comparing annual marriages to annual divorces in a calendar year, a method that confuses flows with stocks and overstates the risk for any individual marriage.\n",

To estimate a lifetime probability for first marriages, we use life-table methods rather than naive compounding, because the hazard is not constant — it peaks around years 5-8 and declines thereafter. The ~42% central estimate draws on the consensus range in family demography literature (roughly 40-45% for all US first marriages, lower for post-2000 and college-educated cohorts). This is consistent with the observed decline from the peak-divorce era: the refined rate fell from ~22.6 per 1,000 in 1980 to 14.2 in 2024, and younger cohorts are divorcing at lower rates than their parents did. The 42% figure is a population average that masks sharp demographic gradients by education, age at marriage, and birth cohort.\n",

Their age-standardized analysis showed that the apparent post-1980 decline in divorce masked rising rates among older adults and genuinely declining rates among younger cohorts. This bifurcated trend is critical to interpreting the lifetime probability: the 42% average blends a lower rate for post-2000 marriages (~35%) with higher rates for older cohorts who married in the peak-divorce era.\n",

The 42% central estimate is a population average for all US first marriages and masks large demographic gradients. For college-educated women who married after 2000, the best available estimates put the figure at roughly 25-30%. For women without a college degree, it is closer to 55-60%. Age at marriage, cohabitation history, and religious participation all shift the number further. The \"50% of marriages end in divorce\" figure was never a cohort estimate — it came from dividing annual divorces by annual marriages in the same calendar year, a method that confuses flows with stocks and has been repeatedly criticized in the demography literature. The rate has been declining for decades, and the decline is concentrated among younger, more educated cohorts.\n",
