a) A 90-percent confidence interval is a measure of an estimate's reliability.
The larger the confidence interval is, in relation to the size of the estimate, the less
reliable the estimate.
(X) Not Applicable. Since the number of housing units is set equal to an independent
national measure, there is no sampling error, and hence no confidence interval.
NOTE: Since first quarter 2003, the Current Population Survey/Housing Vacancy Survey (CPS/HVS)
estimates have been controlled to independent housing unit counts. Doing so should make the
CPS/HVS estimate of housing units more comparable to other Census Bureau housing surveys.
