The width of the confidence intervals for the number insured and the number uninsured are the same. This follows from the fact that the two numbers must add to a known population. A random deviation in one must thus be mirrored exactly in the other, so a measure of variability like the standard deviation must be the same.
Due to rounding, the sum of the state estimates may not equal the national estimate from the Annual Social and Economic Supplement of the Current Population Survey.
