Dual income, no kids: What we know about 'DINKs' in the U.S.

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.
