Demographic D.2 Neighborhood population by race and Hispanic origin
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, 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 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.
Detailed information regarding dasymetric mapping, census data, geographic units of analysis, their definitions, and their boundaries can be found at the following links:

Explanation and Limitations
The US Census asks respondents to indicate their Hispanic heritage and their race seperately. The Census does not consider Hispanic or Latino/a to be a racial category. In 2011 the San Francisco Department of Public Health released Ethnicity Guidelines for collecting, coding, and reporting social identity data (http://www.sfdph.org/dph/files/reports/CommunityProgs/SFDPH_Ethnicity_Guidelines02082011.pdf). These guidelines list Hispanic/Latino/a as a mutially-exclusive core race/ethnicity category along with those categories coded as "races" by the US Census. In order to comply with these guidelines, we report individuals of all races who reported being of Hispanic/Latino/a origins as "Hispanic/Latino/a" and all other non-Hispanic/Latino/a persons by their race selection.
