  • * The unweighted sample sizes are the raw counts observed in the 2001 NIS sample of 23 632 children who were either unvaccinated or had sufficient data reported by their vaccination providers to determine their vaccination status.

  • The weighted percent is the percent of children in the 2001 NIS, each weighted by their sampling weight.
