*

Estimates are considered unreliable. Data preceded by an asterisk have a relative standard error (RSE) of 20%–30%. Data not shown have an RSE greater than 30%.

1

Based on parents responding “yes” to both of the questions, “Has a doctor or other health professional ever told you that your child had asthma?” and “Does your child still have asthma?”

2

Based on parents responding “yes” to both questions, “Has a doctor or other health professional ever told you that your child had asthma?” and “During the past 12 months, did your child have an episode of asthma or an asthma attack?”

3

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

4

The race groups white, black, American Indian or Alaska Native, Asian, Native Hawaiian or 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 1999 data, race-specific estimates are tabulated according to the 1997 Revisions to the Standards for the Classification of 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 the 1997 Standards. Starting with 1999 data, 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 1999, data were tabulated according to the 1977 Standards with four racial groups, and the Asian only category included Native Hawaiian or Other Pacific Islander. Estimates for single-race categories prior to 1999 included persons who reported one race or, if they reported more than one race, identified one race as best representing their race. Starting with 2003 data, race responses of other race and unspecified multiple race were treated as missing, and then race was imputed if these were the only race responses. Almost all persons with a race response of other race were of Hispanic origin. See Appendix II, Hispanic origin; Race.

5

Percent of poverty level is based on family income and family size and composition using U.S. Census Bureau poverty thresholds. Missing family income data were imputed for 1997 and beyond. See Appendix II, Family income; Poverty; Table VII.

6

Health insurance categories are mutually exclusive. Persons who reported both Medicaid and private coverage are classified as having private coverage. Starting with 1997 data, state-sponsored health plan coverage is included as Medicaid coverage. Starting with 1999 data, coverage by the Children’s Health Insurance Program (CHIP) is included as Medicaid coverage. In addition to private and Medicaid, the insured category also includes military, other government, and Medicare coverage. Persons not covered by private insurance, Medicaid, CHIP, state-sponsored or other government-sponsored health plans, Medicare, or military plans are considered to have no health insurance coverage. Persons with only Indian Health Service coverage are considered to have no health insurance coverage. See Appendix II, Health insurance coverage.

7

Based on parents responding “yes” to the question: “Has a doctor or health professional ever told you that your child had attention deficit hyperactivity disorder (ADHD) or attention deficit disorder (ADD)?”

8

Based on parents responding “yes, definite” or “yes, severe” to the question, “Overall, do you think that [child] has difficulties in any of the following areas: emotions, concentration, behavior, or being able to get along with other people?”

9

Based on parents responding “yes” to the question, “During the past 12 months, has your child had any kind of food or digestive allergy?”

10

Based on parents responding “yes” to the question, “During the past 12 months, has your child had any eczema or any kind of skin allergy?”

11

Based on parents responding “yes” to the question “During the past 12 months, has your child had hay fever?” or “yes” to the question, “During the past 12 months, has your child had any kind of respiratory allergy?”

12

Based on parents responding “yes” to the question “During the past 12 months, has your child had three or more ear infections?”
