"Adulting," as it has become known, refers to millennials' ability to complete daily tasks, such as cooking, cleaning and paying their bills on time. It can measure how good they are at being able "to do the things that adults regularly have to do," as Merriam-Webster puts it.

In addition to quotidian tasks like loading the dishwasher and doing laundry, a broader definition of "adulting" includes moving towards larger financial goals, such as buying a home and doing your own taxes.
