Methods

In 2010, the Census long form, which contained a question about individual marital status, was discontinued. The Census short form, which all households are still expected to complete, assesses household relationships by each individual's relationship to the householder. Therefore, one is now only able to assess the marital status of the householder. The householder is the first adult listed on the Census form who is generally the person, or one of the people, in whose name the home is owned, being bought, or rented. If there is no such person in the household, any adult household member 15 years old and over could be designated as the householder. Using the householder's relationship status, the Census defines households as husband-wife households, unmarried partner households, and other households where the householder is unpartnered.

Percent of married households was calculated by dividing the number of husband-wife households, those where the householder has a husband or wife of the opposite sex, by the total number of households.

Percent of unmarried partner households was calculated by dividing the number of unmarried partner households, those where the householder has an unmarried partner of the same or opposite sex, by the total number of households. Unmarried parters include same and opposite-sex couples who marked "unmarried parter" on their Census form and same-sex couples who marked married. 

Percent unpartnered households was calculated by dividing the number of households where the householder has neither a husband or wife nor an unmarried-partner by the total number of households. Unpartnered households may contain married or partnered individuals; however, the householder is not married or partered. An example of this situation would be a married couple living in the home of a parent who is unmarried.

Data Source

2010 US Census. 

Map and table created by San Francisco Department of Public Health, Environmental Health Section using ArcGIS software.

Map data is presented at the level of the census tract. The map also includes planning neighborhood names, in the vicinity of their corresponding census tracts.

Table data is presented by planning neighborhood. While planning neighborhoods are larger geographic areas than census tracts, census tracts do not always lie completely within a planning neighborhood. SFDPH used ArcGIS software and a dasymetric mapping technique to attribute Census block group data to residential lots. We then assigned residential lots to planning neighborhoods to calculate Census population totals within the neighborhoods.
