Reason For Divorce Statistics

Divorce is tied to sharp real life shifts, from 11.7% of adults in households under $40k reporting they are divorced or separated to divorced adults facing about a 20% higher debt risk and a 1.4x jump in food insecurity for single mother headed households. It also comes with a price tag and pressure points most people miss, including median US divorce costs of $15,000 and 46% of divorced adults reporting reduced social support, while parents report major changes in co parenting and children struggle with school performance.
