National Household Education Surveys Program, 2019

An initial sample of 225,500 addresses was selected, of which 205,000 were designated for the NHES:2019. The initial sample of addresses was drawn from a file of residential addresses maintained by Marketing Systems Group (MSG), based on the USPS Computerized Delivery Sequence File (CDSF).

The NHES:2019 sample was a two-phase, stratified sample. In the first phase, a sample of residential addresses was selected from the MSG master address file. In the second phase, an eligible child was selected from information provided in the completed household screener. Households were selected with differential probabilities of selection based on the proportion of households identified as Black and Hispanic in the Census tract in which the address was located. For households that completed the screener and reported at least one eligible child, a child’s probability of selection depended on the number of children in the household and their survey eligibility (ECPP or PFI). These differential probabilities of selection at both phases are accounted for in the NHES weighting methodology. When weights are applied to the NHES topical surveys, the ECPP survey is nationally representative of all children from birth through age 6 who were not yet enrolled in kindergarten and the PFI survey is nationally representative of students enrolled in grades K–12, including children who were enrolled in public or private school, and those who were homeschooled for the equivalent grades.

Data were collected using a two-phase survey (conducted primarily by mail), which used an address-based sample covering the 50 states and the District of Columbia. As described in detail in the user's manual, households were randomly sampled, and a screening questionnaire was sent to each sampled household. Households that were eligible for further surveying received a longer, topical survey.

The ECPP survey files contain data from surveys completed with the parents or guardians of 7,092 children age 6 or younger who are not yet enrolled in kindergarten. The PFI survey files contain data from surveys completed with the parents or guardians of 16,446 children age 20 or younger who are enrolled in kindergarten through 12th grade in a public or private school or who are being homeschooled for the equivalent grades.

The ECPP file contains 625 variables. The PFI file contains 828 variables.

Only Restricted-Use NHES data has variables which allow for linkages. The geographic identifiers within NHES permit data users to merge on any data available at the state, CBSA, county, NECTA, ZCTA, census tract, or census block group-level, such as population characteristics from the ACS. While this is possible it should be noted that the NHES is not designed to create sub-national estimates.
