targets are US rate; note high margins of error (eg 2015: 32.0 +/- 6.46)

This disability type is based on the question (asked of persons ages 5 or older): Because of a physical, mental, or emotional condition, does this person have serious difficulty concentrating, remembering, or making decisions?

'Target' value is national rate. Note high margins of error for estimated state rate. Caution should be used when interpreting a statistic based on small sample sizes or when the Margin Of Error (MOE) is large relative to the estimate. The MOE is a measurement of the accuracy of the statistic. We highly recommend that you indicate the sample size and MOE when reporting a statistic.
