20,954 rated or chosen profiles from 1,311 respondents, in up to 8 tasks of 2 profiles varying on 10 attributes.
| Description | Paired forced-choice conjoint in which 1,311 US adults (Verasight, July 2024) chose which of two hypothetical immigrants should be given priority to come to the United States, over 8 pairs; ten attributes include the immigrant's expected place of residence (the United States, the respondent's state, city or neighborhood). Outcome: choice; survey weight included. |

| Randomization restrictions | yes (stated by the source): Computer programmer, Doctor, Financial analyst, Research scientist only with education of two years of college or more; 'Escape political/religious persecution' only for Iraq, Somalia, Sudan (authors' script 'model formula with restrictions' Education*Job + Reason*Country; the data show exactly these empty cells). Level shares are unequal as a consequence (e.g. reason persecution 13%, college-or-more education levels ~18% vs ~11% for lower levels). |
| Task order | inferred from row order |
| Profile position | inferred from row order |
Because the attribute levels were not randomized independently, an estimator has to account for the restriction; a plain difference in means across levels can mislead. Task order or profile position was rebuilt from row order; analyses of position or task order should leave it out.
Outcomes:
| choice | If you had to choose between them, which of these two immigrants should be given priority to come to the United States to live? [choice, forced] |
