Lottery Wins May Increase Divorce Risk for Women, Study Suggests

Winning the lottery, often envisioned as a path to marital bliss, may paradoxically increase the likelihood of divorce for some women, according to a recent study. The research suggests that while a substantial financial windfall can bolster marriages for men, it appears to have an opposite effect on married women.

The study, published in the Journal of Human Resources, analyzed the outcomes for over 76,000 Swedish lottery players. Researchers linked lottery records with government data on marriage, divorce, and childbirth, tracking participants for up to a decade after their winnings.

Key findings indicate that for men, lottery wins are associated with increased marriage formation and fertility, and potentially a reduced risk of divorce. In contrast, the research found that for women, a significant lottery win is linked to a higher short-run divorce risk.

Specifically, winning the equivalent of approximately $105,000 was found to effectively double the short-term risk of divorce for married women within two years. However, this elevated risk appears to diminish over time, suggesting that sudden wealth may accelerate the dissolution of marriages that were already facing instability. Researchers hypothesize that increased financial independence might make single life more appealing to women who experience a heavier domestic workload or have less autonomy within their marriages.

The study also noted that lottery wins generally increased fertility, particularly among men, which the researchers attribute in part to improved relationship stability and marriage prospects associated with newfound wealth. For single women, the study found no significant impact of lottery winnings on their relationships.

Real-life examples appear to align with the study's findings. Adrian and Gillian Bayford, who won £148 million (approximately $200 million USD) on EuroMillions in 2012, divorced just 15 months later. Colin and Chris Weir, who won £161 million (approximately $218 million USD) in 2011, announced their intention to divorce in 2019. Roger and Lara Griffiths, lottery winners of £1.8 million (approximately $2.4 million USD) in 2005, split in 2013 amid reported financial difficulties.

The research was conducted by a team from New York University, Stockholm University, the Stockholm School of Economics, and the University of Barcelona.
