= National Household Education Survey = The '''National Household Education Survey''' ('''NHES''') is a national survey administered by NCES. <> ---- == Design == === Frequency === The survey is administered every 3 or 4 years. === Sampling === The survey is administered as two phases. The first screener phase collects information about the household composition. The target population is non-institutionalized, civilian members of households in the 50 states plus [[UnitedStates/WashingtonDC|DC.]] An [[Statistics/SurveyFrame#ABS_Frames|address list]] is used to select the sample of about 200,000. Black and Hispanic households are [[Statistics/SurveySampling#Stratification|oversampled]]. An initial invite and several reminders are sent to all selected addresses. The second phase is a topical survey, and the eligibility criteria can change year to year. Using screener responses, households with eligible children are selected for the second phase, a topical questionnaire. If there are multiple eligible children, the sampling process selects one. Note that the survey is administered to an adult on behalf of the selected child. === Weighting === The [[Statistics/SurveyWeights|base weights]] reflect unequal stage 1 sampling probabilities. Base weights are adjusted for screener [[Statistics/NonResponseBias|non-response bias]]. A within-household sampling adjustment accounts for unequal probability of selection. Topical surveys then have separate weights. Principally they reflect the respective target populations. The within-household adjusted weights are further adjusted for non-response and [[Statistics/SurveyInference#Sampling_Error|coverage bias]] of that particular survey's sample and instrument. Weights are raked to benchmarks from either the [[UnitedStates/CensusBureau/AmericanCommunitySurvey|ACS]] or [[UnitedStates/CensusBureau/CurrentPopulationSurvey|CPS]], depending on which has a superior sample size. ---- == History == Prior to the 2012 survey's administration, the sample was selected using [[Statistics/SurveyFrame#RDD_Frames|RDD]]. Also in 2012, the within-household sampling procedure was developed to reduce survey burden. No household can be selected for more than one survey. ---- CategoryRicottone
