Footnotes

The profile universe is limited to the household population and excludes the population living in institutions, college dormitories, and other group quarters. Data are based on a sample and are subject to sampling variability.

For the characteristic Selected Monthly Owner Costs as a Percentage of Household Income, the percent distributions are calculated based on the total number of Specified Owner-Occupied Housing Units with a Mortgage and Specified Owner-Occupied Housing Units without a Mortgage minus the number of Specified Owner-Occupied Housing Units in the not computed category.

For the characteristic Gross Rent as a Percentage of Household Income, the percent distributions are calculated based on the total number of Specified Renter Occupied Units minus the number of units in the not computed category.

For the characteristic Gross Rent, the percent distributions and medians are calculated based on the total number of Specified Renter Occupied Units minus the number of units in the no cash rent category.

1. An '-' entry in an Estimate column indicates that no sample observations were available to compute an estimate.
2. An '-' following a median estimate means the median falls in the lowest interval of an open-ended distribution.
3. An '+' following a median estimate means the median falls in the upper interval of an open-ended distribution.
4. An 'N' entry in an Estimate column indicates that data for this geographic area cannot be displayed because the number of sample cases is too small.
