Divorce Rates
Divorce rates rose sharply across most advanced economies after no-fault divorce laws passed in the late 1960s and 1970s. The US crude divorce rate peaked at 5.3 per 1,000 in 1979–81; it has since fallen to ~2.4. Similar declines in many European and Asian countries since 2000 — partly because fewer people marry in the first place (selection effect). Russia maintains the highest divorce rates among major economies.
Key insights
Divorce has fallen from its 1980 peak
US divorce rates peaked at 5.3/1,000 around 1980 after no-fault divorce laws were enacted state-by-state. Since then, US divorce has fallen ~55% to ~2.4/1,000. Similar declines in many advanced economies. Why: fewer marriages overall (selection — people who would have divorced just don't marry), older age at marriage (more stable selection), education-marriage gradient (educated couples marry later and divorce less).
Russia and post-Soviet states top divorce rates
Russia: ~4.7/1,000 (close to global high). Belarus, Latvia, Ukraine, Lithuania all in similar range. Drivers debated — alcohol-related stress, housing shortages, gender-norm clashes, and high marriage rates that produce more marriages-to-dissolve. Russian total divorce rate (divorces per first-marriage cohort) approaches 60%. The pattern has been stable across decades.
'Gray divorce' is the rising US trend
Among older adults (50+), the US divorce rate has roughly doubled since 1990 — even as overall divorce has fallen. Drivers: empty-nest reassessment, longer life expectancy (more decades to anticipate), financial independence of older women, lower social stigma. The trend is reshaping retirement planning, housing markets in some segments, and long-term-care demand.

Crude divorces per 1,000 population
Key Finding: Peaked around 1980; sustained decline since then.
Methodology & caveats
CDR vs refined divorce rate
Crude divorce rate = divorces / total population × 1,000. Refined rate = divorces / married women × 1,000. The refined rate is more meaningful but harder to compare across countries. The two can diverge as marriage rates change — fewer marriages → lower CDR even at higher per-marriage divorce probability.
Lifetime divorce probability
Cumulative probability that a first marriage ends in divorce: ~40-50% in the US (post-1970 cohorts), ~35-45% in Northern Europe, ~10-20% in Southern Europe, varies widely in Asia. The figure has been roughly stable for 30 years but composition has shifted — fewer first marriages, more remarriages, more cohabitation that doesn't show up in divorce statistics.
India's low rate has multiple explanations
India's official divorce rate (0.1/1,000) is among the lowest in the world. Factors: religious and social stigma, women's economic dependence on marriage, family pressure, low formal divorce registration even when couples separate. Actual relationship dissolution probably much higher than official statistics indicate; legal divorce is rare for many of these other reasons.
