The Knot Yet Project found unmarried 20-somethings as more likely to drink excessively and suffer from depression than their married counterparts. As far as life-satisfaction goes, “35 percent of single men and cohabiting men report they are “highly satisfied” with their life, compared to 52 percent of married men. Likewise, 33 percent of single women and 29 percent of cohabiting women are “highly satisfied,” compared to 47 percent of married women.” In the end, married 20 year olds are happier than unmarried 20 year olds.
