  • During 2015–2018, US children and adolescents drank an average of 23 ounces of plain water daily, and US adults drank an average of 44 ounces.
  • Among US children and adolescents, plain water intake is significantly lower in younger children, non-Hispanic Black children or Hispanic children (compared to non-Hispanic White children), those living in lower-income households, youth whose head of household had less than a high school education (compared to college or higher), and those who are underweight or normal weight (compared to those with obesity) (Table 1).
  • Among US adults, plain water intake is significantly lower in older adults, non-Hispanic Black adults (compared to non-Hispanic White adults), adults with lower income and lower education, and adults without obesity (Table 2).
