Fines and fees can impose heavy burdens on those who come into contact with the criminal legal system. Using nationally representative data from the Urban Institute’s 2023 Well-Being and Basic Needs Survey, we examined the prevalence of fines and fees among nonelderly adults’ households, including the types of violations resulting in fines and fees, the populations impacted, and the consequences of these costs. About one in six adults incurred fines and fees in 2023, largely from traffic or parking tickets. Court or incarceration-related fines and fees disproportionately affected people of color and those with low incomes. Compared with adults who only incurred costs from traffic or parking tickets, those with court or incarceration-related fines and fees faced higher amounts charged, greater financial strain to make payments, and a higher likelihood of adverse consequences for being unable to pay, such as driver’s license suspensions, additional fees, or time in jail. They also faced higher rates of food insecurity and other material hardships. Our findings contribute to the growing evidence base on the impacts of fines and fees on family well-being.
