Supplementary information
SI Table A-1 (demographic characteristics, continuous variables), Age
Published
Table A-1, Age, all respondents: Min 1940, median 1964.0, mean 1965.3, Max 2014
Correction
Corrected Table A-1, with age in years: 19 to 101, median 43, mean 44.3.
Corrected SI Table A-1, Age: age in years (2015 minus birth year), unweighted, by racial group. Variable Levels n Min q1 Median Mean q3 Max s IQR Age White 800 19 36 53.0 50.3 63 93 16.5 27 White-Black 720 19 26 37.0 41.0 55 101 16.9 29 White-Asian 509 19 25 35.0 38.3 49 82 14.8 24 Black 500 19 35 44.5 45.7 56 87 14.4 21 Asian 500 19 32 44.0 44.2 55 84 14.4 23 all 3,029 19 30 43.0 44.3 58 101 16.2 28 Basis preprocess.r computes age as 2015 minus as.numeric(birthyr). In the deposited multiracial.sav, birthyr is a factor, so as.numeric() returns the position of each birth year in the list of years observed, and the result is a number between 1940 and 2014. The corrected table uses 2015 minus the birth year.
SI Table A-2 (demographic characteristics, nominal variables), Education
Published
Table A-2, Education: “Less than HS” 703 (23.2%) of all respondents and 299 (37.4%) of Whites
Correction
The category is “HS or less.” It combines respondents without a high school diploma (66, 2.2% of the sample) and high school graduates (637). The counts are unchanged.
Corrected SI Table A-2, Education rows, in the published layout (counts and percent of each group). The first category combines “No HS” and “High school graduate” (preprocess.r); the counts are unchanged and only the label is corrected. Variable Levels nWhite %White nWhite-Black %White-Black nWhite-Asian %White-Asian nBlack %Black nAsian %Asian nall %all Education HS or less 299 37.4 113 15.7 58 11.4 195 39.0 38 7.6 703 23.2 Some College 243 30.4 301 41.8 187 36.7 191 38.2 122 24.4 1,044 34.5 College Grad 258 32.2 306 42.5 264 51.9 114 22.8 340 68.0 1,282 42.3 Basis The education recode in preprocess.r leaves “No HS” (code 1) in place and moves “High school graduate” (code 2) into the same category, which it labels “Less than HS.” The regressions use this category as the omitted reference, so no coefficient changes.
SI Tables B-1 to B-5, intercepts
Published
Intercepts of Tables B-1 to B-5, estimated with the age variable from preprocess.r (for example, 9.45 for linked fate to Asians in Table B-3)
Correction
Corrected intercepts, with age in years. For linked fate to Asians (Table B-3), the intercept is 0.74.
Intercepts of the regressions in SI Tables B-1 to B-5 with age in years. Weighted OLS as in analysis.r; 95% confidence intervals in brackets. All other coefficients are unchanged at two decimals. Table Outcome Intercept, age coded as in preprocess.r Intercept, age in years B-1 Relative salience of race 0.93 [−0.64; 2.51] −0.16 [−0.21; −0.10] B-2 Closeness to Whites −1.35 [−2.74; 0.03] 0.70 [0.65; 0.74] B-2 Closeness to Blacks −0.09 [−1.52; 1.33] 0.77 [0.72; 0.82] B-2 Closeness to Asians −0.58 [−1.99; 0.84] 0.71 [0.66; 0.76] B-3 Linked fate to Whites 1.38 [−0.47; 3.23] 0.58 [0.52; 0.65] B-3 Linked fate to Blacks 1.31 [−1.08; 3.71] 0.69 [0.62; 0.77] B-3 Linked fate to Asians 9.45 [7.08; 11.82] 0.74 [0.66; 0.82] B-4 White stereotypes −3.40 [−4.97; −1.83] 0.11 [0.05; 0.16] B-4 Black stereotypes 2.09 [0.16; 4.02] 0.07 [0.01; 0.14] B-4 Asian stereotypes −1.22 [−2.83; 0.38] 0.39 [0.33; 0.45] B-5 Resentment −5.48 [−6.84; −4.12] 0.52 [0.47; 0.57] B-5 White-Black D-score 1.88 [−1.42; 5.19] 0.18 [0.07; 0.29] B-5 White-Asian D-score 2.56 [−0.74; 5.86] 0.17 [0.06; 0.29] Basis The regressions control for the age variable described in the correction to Table A-1, which equals age in years plus 1,921 for all but 4 respondents. The intercepts are therefore predictions for an age of about −1,921. The age coefficients and the racial-group estimates in Tables B-1 to B-5, and so Figures 1–5, are unchanged at two decimals.
