1. Land area of the census blocks that approximate the area. The same boundaries were used for both 2000 and 2010; any
differences in land area between 2000 and 2010 reflect changes to census block geography.
2. In combination with one or more of the other races listed. The six numbers may add to more than the total population, and the
six percentages may add to more than 100 percent because individuals may report more than one race.
3. "Spouse" represents spouse of the householder. It does not reflect all spouses in a household. Responses of "same‐sex spouse"
were edited during processing to "unmarried partner."
4. "Family households" consist of a householder and one or more other people related to the householder by birth, marriage, or
adoption. They do not include same‐sex married couples even if the marriage was performed in a state issuing marriage
certificates for same‐sex couples unless there is at least one additional person related to the householder by birth or adoption.
Same‐sex couple households with no relatives of the householder present are tabulated in nonfamily households. "Nonfamily
households" consist of people living alone and households which do not have any members related to the householder.
5. Percentage distribution of ownership categories ("owned with a mortgage or a loan" and "owned free and clear") adds to 100
percent.
6. Percentage distribution of vacancy categories ("for rent," etc.) adds to 100 percent.
