January 2023
United States
1984 to 2019
under 65 years
* Data prior to 1997 are not strictly comparable with data for later years due to the 1997 questionnaire redesign.
Estimates for 2000-2002 were calculated using 2000-based sample weights and may differ from estimates in other reports that used 1990-based sample weights for 2000-2002 estimates.
Beginning in quarter 3 of the 2004 NHIS, persons under 65 years with no reported coverage were asked explicitly about Medicaid coverage. In this statistic, estimates were calculated with the additional information starting with 2005 data.
Values not included in the pdf version of the report were taken from the Health, United States, trend tables.
