9,216 rated or chosen profiles from 384 respondents, in up to 12 tasks of 2 profiles varying on 5 attributes.
| Description | Residents of Siechnice (Poland) chose between two described visions of the town's development in 12 tasks, or neither, in a paper-and-pencil survey. 384 respondents, 12 tasks x 2 profiles, 5 attributes (city direction, public investment, housing form, social policy, environment) in Polish. |

| Randomization restrictions | observed in the data (not documented by the source): fixed blocked design (24 cards, 5 blocks of 12 tasks, idefix); 27 of 176 level pairs across attributes never occur together, and level shares range 17-29% within an attribute (the first attribute has 5 levels, the others 4) |
| 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:
