(DINK) Dual Income, No Kids

"DINK" is an acronym used to describe a household where both partners have an income and do not have children. This term is often used to describe a demographic group that is characterized by their high level of disposable income and their focus on spending on themselves and their lifestyle, rather than on supporting a family. People in this demographic may be focused on saving for the future, traveling, pursuing hobbies or other interests, or simply enjoying a more carefree lifestyle.
