DINK is an acronym that stands for "Dual Income, No Kids". It describes a couple who do not have children. One factor for forming such a couple is when a female wants to be a career woman, rather than following the "mommy track".

The term was coined in the 1980s at the height of "yuppie" culture. The Great Recession has solidified this social trend as more couples wait longer to have kids. In the Netherlands, one in five couples choose not to have them at all.
