ACS and LTDB Race Data by Community Reporting Area

Abstract: Census tract-based race and ethnicity data aggregated to City of Seattle Community Reporting Areas (CRAs) from the 1990 and 2010 Brown University Longitudinal Database (LTDB), 2010 decennial census and the 2014-2018 5-year American Community Survey (ACS).  Brown University researchers created the LTDB to allow for comparing census data over time (see https://s4.ad.brown.edu/projects/diversity/Researcher/Bridging.htm). The  race and ethnicity categories in the 2010 LTDB  have been modified from those in the 2010 census to more closely match the 1990 race categories. (Before 2000, census questionnaires allowed respondents to identify as one race only. The LTDB allocates mixed-race people in post-1990 census estimates to non-white categories.)  Please remember that the ACS data carry margins of error, and for small racial/ethnic groups they can be significant. The numeric and percentage changes overtime are also included. There is also a polygon representation for the City of Seattle as a whole.Purpose: Census data of racial and ethnic categories from 1990 and 2010 Brown University LTDB, 2010 decennial and 2018 American Community Survey (ACS). Data is for the City of Seattle Community Reporting Areas as well as a polygon representation for the City of Seattle as a whole.  Numeric and percentage changes over time are also included.
