Screener Questionnaire item number: 1,2 Variable in public use data file: SC_HISPANIC_R; SC_RACE_R
Children age 0-17 years
Hispanic children; White, non-Hispanic children; Black, non-Hispanic children; Other, non-Hispanic children
Revisions and Changes:
In 2018 this measure did not change from the 2017 NSCH.
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 is included as SC_HISPANIC_R. Hispanic origin and race information for the selected sample child was provided in the "Topical" public use file provided by the Census Bureau. For race4_1718, 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/Alaska Native, Native Hawaiian/other Pacific Islander, or 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% (2018) - 1.1% (2017) missing cases and race had 0.3% (2018) - 0.8% (2017) missing values. The 2017- 2018 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 may be due to non-response (i.e. a skipped item) or a “don’t know” response. The way these items are handled can vary by measure. For NPMs and NOMs, having missing values for all items in an indicator will lead to the case being given a missing value on the overall measure. For some other measures, if there is a missing value on any of the items, the case will be set to missing. How missing values are handled is documented in the "Additional notes" field above when required.
Missing values are not included in the denominator when calculating prevalence estimates and weighted population counts displayed in the Interactive 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.).

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 (in 2015) 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 and 2018 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.
