Demographic D.2 Neighborhood population by race and Hispanic origin
* In this table, the Hispanic / Latino category is not a mutually exclusive race category. Thus, the percent Hispanic should not be added to percentages for racial categories. Tallies that show race categories for Hispanics and non-Hispanics separately are available. In the U.S. Census, people of Hispanic origin may be of any race and are asked to answer the question on race by marking one or more race categories shown on the questionnaire, including White, Black or African American, American Indian or Alaska Native, Asian, Native Hawaiian or Other Pacific Islander, and Some Other Race. Hispanics are asked to indicate their origin in the question on Hispanic origin, not in the question on race, because in the federal statistical system ethnic origin is considered to be a separate concept from race. Hispanics or Latinos are those people who classified themselves in one of the specific Spanish, Hispanic, or Latino categories listed on the Census 2000 questionnaire. People who identify their origin as Spanish, Hispanic, or Latino may be of any race.
Data Source
Applied Geographic Solutions, Inc. Spring 2007 Update: Current Year Estimates. Methodology available at: http://www.appliedgeographic.com/library.html.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, which was calculated by assigning census block data to census tracts based on spatial location. 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 'centroids within' methodology to convert census blocks to geographic mean center points. We then assigned census blocks to planning neighborhoods based on the spatial location of those geographic mean center points and calculated the planning neighborhood totals for the table.
