In the United States, 12% of married couples with at least one spouse in their 30s or 40s have two incomes and no kids, according to a Pew Research Center analysis of federal data.
This group, often referred to as “DINKs,” has grown slightly over the past decade. In 2013, 8% of married couples in the same age range were DINKs.
The share of dual-income couples with kids has also inched up slightly since 2013, while the share of single-income couples with kids has decreased from 34% to 27%.
