aA 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.
