Survey Items: Screener Questionnaire item number: 1,2 Variable in public use data file: SC_HISPANIC_R; SC_RACE_R
Denominator: Children age 0-17 years
Numerator: Hispanic children; White, non-Hispanic children; Black, non-Hispanic children; Other, non-Hispanic children
Revisions and Changes: In 2017, this item did not change from the 2016 NSCH. Due to changes in the administration and sampling for the NSCH, results from surveys prior to 2016 are not directly comparable and should not be used to conduct trend analyses. In the 2016 and 2017 NSCH, detailed race categories for Asian were included in response options: Asian Indian, Chinese, Filipino, Japanese, Korean, Vietnamese, other Asian. Additional specific race categories for Pacific Islander such as Guamanian or Chamorro and Samoan were included in the 2016 and 2017 NSCH. These data are not released in the public use files.
Additional Notes: The questions about child's Hispanic origin and race were asked in the initial screening questionnaire. Responses to the race question are combined into SC_RACE_R. Responses to the question about Hispanic, Latino or Spanish origin are included as SC_HISPANIC_R. Hispanic origin and race information for the selected sample child were provided in the "Topical" public use file provided by the Census Bureau. Children reporting Hispanic or Latino ethnicity (SC_HISPANIC_R=1) are counted as Hispanic regardless of reported race in SC_RACE_R. Non-Hispanic children (SC_HISPANIC_R=2) are grouped by race based on SC_RACE_R. Non-Hispanic children reporting only one race category of Asian, American Indian or Alaska Native, Native Hawaiian or other Pacific Islander, and some other race are grouped as "Other, non-Hispanic" because of small sample sizes in many states. Non-Hispanic children who reported more than one race are categorized as "Other, non-Hispanic". Hispanic origin had 0.6% (2016) – 1.1% (2017) missing cases and race had 0.3% (2016) - 0.8% (2017) missing values. The 2016- 2017 NSCH data set includes single imputed values for these missing cases in the variables SC_HISPANIC_R and SC_RACE_R.
Treatment of Unknown Values: Missing values due to non-response or a “don’t know” response are not included in the denominator when calculating prevalence estimates and weighted population counts displayed in the data query results table. In the majority of cases, the proportion of missing values is less than 2%. Exceptions are noted in the form of a Data Alert at the bottom of a results table. The exclusion of these values does not change the prevalence estimates (%) and only marginally affects the weighted population counts (Pop. Est.). If missing cases are handled in any other way, details can be found in the "Additional notes" section above.
History and Development: The Health Resources and Services Administration’s (HRSA) Maternal and Child Health Bureau (MCHB) funds and directs the National Survey of Children’s Health (NSCH) , and develops survey content in collaboration with the U.S. Census Bureau and a Technical Expert Panel. The Technical Expert Panel consists of experts in survey methodology and children’s health, federal and state stakeholders, clinicians and researchers. The U.S. Census Bureau conducts the survey, oversees the sampling, and produces a final data set of survey results. Respondents’ cognitive understanding of the survey questions was assessed during the pretest phase of the survey redesign and reassessed after the 2016 survey; subsequent revisions were made. Previously validated questions and scales are used when available. The manuscript “The Design and Implementation of the 2016 National Survey of Children’s Health”, provides detailed information about the redesign of the NSCH, administration of the first redesigned survey (2016), and the sampling and administration changes for the 2017 NSCH. Prior to 2016, the NSCH and the National Survey of Children with Special Health Care Needs were each conducted three times as interviewer-assisted telephone surveys using random digit dial sampling. In 2016, the two surveys were combined into a single annual self-administered questionnaire. Due to decline in the number of households with landline telephones, the NSCH now utilizes an addressed based sampling method to select participating households, thus all invitations are sent by mail. Participants may choose to complete the survey either online using a secure website or a mailed paper version of the survey. All final data components are verified by the Census Bureau, HRSA/MCHB and CAHMI/DRC staff prior to public release. More information about the survey can be found in the “About the National Survey of Children's Health” section of this website and HRSA’s MCHB website.
C.I. = 95% Confidence Interval. Percentages and population estimates (Pop.Est.) are weighted to represent child population in US. Please interpret with caution: estimate has a 95% confidence interval width exceeding 20 percentage points or 1.2 times the estimate and may not be reliable.

DATA ALERT: CSHCN Status is determined using a validated instrument for identification of children with special health care needs as defined by the federal Maternal and Child Health Bureau. The CSHCN Screener asks whether a child currently experiences a health consequence and, if so, whether that specific health consequence is due to a medical, behavioral, or other type of health condition that has lasted, or is expected to last, 12 months or longer. For more information, email info@cahmi.org. State samples for Black and Hispanic Origin are too small (n<30) in the following states and should not be used to derive population estimates: • Black: AK, AZ, CO, HI, ID, IA, KS, ME, MT, NE, NH, NM, ND, OR, SD, UT, VT, WV, WI, WY; • Hispanic Origin: AL, ME, MS, VT, WV Missing values (Hispanic origin: 0.57% and race: 0.32%) were estimated using single imputation methods.
