(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.
\1 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 estiamte, the less reliable the estimate.
