Children who missed 11 or more days of school per year due to illness or injury in United States

The state-level data used here come from the National Survey of Children’s Health (NSCH). The NSCH includes information on over 102,000 children under age 18, with roughly 2,000 children per state. Households were selected through a random-digit-dial sample, and one child was randomly selected in each household. Information on each child is based on responses of the parent or guardian in the household who was most knowledgeable about the sampled child’s health. Information was collected via a computer-assisted telephone interview. For more information on the NSCH, see http://www.cdc.gov/nchs/about/major/slaits/nsch.htm.

Data for the 2011-2012 NSCH were collected February 2011 through June 2012. Additionally, cell phones were contacted for the first time in 2011-2012, so trend comparisons should be made with caution.
