    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.
