CI, confidence interval; FPL, Federal Poverty Level.
The sum of the sample sizes within each stratum might not equal the total surveyed because some parents did not know or refused to provide an answer to the question about the characteristic. Missing data for federal poverty level were derived using multiple imputation techniques. Missing data for child sex, race, and ethnicity were imputed using hot-deck imputation. Highest level of parent education (missing n = 879).
Residence in or not in a metropolitan statistical area (MSA) was used as a proxy for urbanicity. Children living in an MSA were considered to be living in an urban/suburban area, and children not living in an MSA were considered to be living in a rural area. Estimates related to urbanicity were calculated using restricted data accessed by the Health Resources and Services Administration because some geographic information is suppressed in the public use file to protect respondent confidentiality; unweighted counts have been rounded as part of the disclosure review process and do not sum to the overall n. The US Census Bureau reviewed this data product for unauthorized disclosure of confidential information and approved the disclosure avoidance practices applied to this release (CBDRB-FY20-POP001-0156).
