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.

N.A. – Data not available.
Note: Maps use the natural break classification method, which reflects patterns
in the data by dividing the map into naturally occurring groups. Using statistical tools, this method
determines cut-off points for each group by identifying large gaps in data values.
Note: The District of Columbia, Puerto Rico and the U.S. Virgin Islands are
not included in maps and rankings because they are not states and therefore comparisons on many
indicators of child well being are not meaningful.
