A note on sample size
In both individual year and multi-year analyses, the NSCH sample size may be limited for smaller populations (e.g., American Indian (AI) /Alaska Native (AN)) and state-level subgroups or rare outcomes (e.g., adolescent children with special health care needs (CSHCN) or autism in a particular state).
Small sample sizes may produce unstable estimates.
To minimize misinterpretation, we recommend only presenting statistics with a sample size or unweighted denominator of 30 or more.
Additionally, if the 95% confidence interval width exceeds 20 percentage points or 1.2 times the estimate (≈ relative standard error>30%), we recommend flagging for poor reliability and/or presenting a measure of statistical reliability (e.g., confidence intervals or statistical significance testing) to promote appropriate interpretation.
