  1. ASSESSING THE ETHNIC/RACIAL DIVERSITY OF AMERICAN PUBLIC OPINION Marisa Abrajano and Keith T. Poole UCSD October 2008

  2. The Problem • Major concern for scholars studying subgroup populations-- availability of adequate survey data. • Makes it difficult to examine the ethnic/racial differences in American public opinion beyond the Black-White dichotomy.

  3. Example: Sample Sizes 2004 NES Annenberg Census Whites 876 67,851 71.9% Blacks 180 6,550 10.7 Hispanics 81 6,155 11.8 Other 75 ***** 5.5 Total 1,212 81,422 100.0

  4. Our Approach • Develop a method for linking respondents from different surveys based on their internal (subjective) utility from political stimuli. • Measure of subjective utility: feeling thermometers. • Thermometer Score = f [Ui(X, Z)]

  5. Linking Procedure For each respondent in the larger sample (Annenberg), search for the respondent in the smaller sample (ANES) with the closest set of thermometer scores. Linked dataset produces: Annenberg respondents who have “answered” all of the ANES questions.

  6. Link Score Link Score = k=1|ri –rj | K

  7. Another Check of the Linked Data

  8. 2nd Linking Procedure Both sets of respondents answer the same 10 thermometer questions. Treat them as a joint sample and scale them using old fashioned metric unfolding. The result is a spatial map with both sets of respondents in the same space.

  9. Conclusions • Linking procedure offers researchers one way of analyzing subpopulations. • Heterogeneity in public opinion exists between and across ethnic/racial groups.
