Data prior to 1997 are not strictly comparable with data for later years due to the 1997 questionnaire redesign. See Appendix I, National Health Interview Survey.


Persons who report the emergency department as the place of their usual source of care are defined as having no usual source of care. See Appendix II, Usual source of care.


Includes all other races not shown separately and unknown health insurance status.


The race groups, white, black, American Indian and Alaska Native (AI/AN), Asian, Native Hawaiian and Other Pacific Islander, and 2 or more races, include persons of Hispanic and non-Hispanic origin. Persons of Hispanic origin may be of any race. Starting with data years 1999–2000 race-specific estimates are tabulated according to 1997 Standards for Federal data on Race and Ethnicity and are not strictly comparable with estimates for earlier years. The five single race categories plus multiple race categories shown in the table conform to 1997 Standards. The 1999–2000 race-specific estimates are for persons who reported only one racial group; the category “2 or more races” includes persons who reported more than one racial group. Prior to data years 1999–2000, data were tabulated according to 1977 Standards with four racial groups and the category “Asian only” included Native Hawaiian and Other Pacific Islander. Estimates for single race categories prior to 1999–2000 included persons who reported one race or, if they reported more than one race, identified one race as best representing their race. The effect of the 1997 Standard on the 1999–2000 estimates can be seen by comparing 1999–2000 data tabulated according to the two Standards. Estimates based on the 1977 Standard of the percent of children under 18 years of age with no usual source of care are: identical for white children; 0.1 percentage points lower for black children; 0.6 percentage points lower for AI/AN children; and 1.0 percentage points lower for Asian and Pacific Islander children than estimates based on the 1997 Standards. See Appendix II, Race.


Poor persons are defined as below the poverty threshold. Near poor persons have incomes of 100 percent to less than 200 percent of the poverty threshold. Nonpoor persons have incomes of 200 percent or greater than the poverty threshold. Missing family income data were imputed for 14 percent of children in 1993–96. Starting with Health, United States, 2004 a new methodology for imputing family income was used for data years 1997 and beyond. Missing family income data were imputed for 21–25 percent of children under 18 years of age in 1997–98 and 28–30 percent in 1999–2002. Therefore, estimates by poverty for 1997–2001 differ from those in previous editions of Health, United States. See Appendix II, Family income; Poverty level.


Health insurance categories are mutually exclusive. Persons who reported both Medicaid and private coverage are classified as having private coverage. Medicaid includes other public assistance through 1996. Starting in 1997 Medicaid includes state-sponsored health plans and State Children’s Health Insurance Program (SCHIP). The category “insured” also includes military, other State, and Medicare coverage. Health insurance status was unknown for 8–9 percent of children in the sample in 1993–96 and 1 percent in 1997–2002. See Appendix II, Health insurance coverage.


MSA is metropolitan statistical area.
