Estimates for 2010 to 2019 are based on the 2010 census, those from 2020 on the 2020 census. The Census Bureau does not join the two series, so part of any step between 2019 and 2020 comes from the new base, not from a change in population.

Ages

In 2025, 19.7% of the people in Hawaii were under 18 and 22.6% were 65 or older. For the United States: 21.1% and 18.9%.
