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.

The number of householders does not necessarily equal the number of households because of differences in the weighting schemes for the population and occupied housing units.

For more information on understanding race and Hispanic origin data, please see the Census 2000 Brief entitled, Overview of Race and Hispanic Origin, issued March 2001. (pdf format)

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.
