While dual-income, no-kids (DINK) households once seemed uncommon, they’re now the norm. According to the latest U.S. Census Bureau estimates, fewer than half of all U.S. households in 2025 were married couples, and among those, only 37% included children under 18—down from 54% in 1975. This means the majority of married-couple households today are child-free, reflecting a major demographic shift. As the population of DINKs continues to grow, the question becomes more pressing: are DINK couples happier with this lifestyle, or simply living differently?
