| Randomization restrictions | observed in the data (not documented by the source): never observed: 'Born in the country with both parents born in the country' with Permanent or Temporary residency or with 'Does not speak language'; 'Born in the country with both parents born abroad' with Temporary residency. Migration-background levels each ~20%, but legal status (Citizenship ~49%) and language (fluent ~58%) shares are unequal as a consequence of the restrictions |
| Task order | recorded in the deposit |
| Profile position | recorded in the deposit |
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 resident family members should be allowed to bring their family member to the country? (paraphrase) [choice, forced] |
|---|---|
| rating | Rating of the resident family member's case for family reunification, 1-7 (paraphrase) [rating, 1 (unknown) to 7 (unknown)] |
