| Respondents | 652 |

| Randomization restrictions | observed in the data (not documented by the source): German and Austrian applicants never have 'Adequate' German; age '21 Years' never with '29 Years' since arrival. Level shares unequal: origin Italy and Turkey ~26% each vs ~6-9% for the other six; language 'Perfect' 52%; age '21 Years' 20%; residency '29 Years' 20%. |
| Task order | recorded in the deposit |
| Profile position | unknown |
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.
Outcomes:
| choice | Which of the two immigrant applicants do you prefer for naturalization? (paraphrase) [choice, forced] |
