Survey Results

While the survey has been active, we have been providing daily snapshots of the results in this page. Here you can find a list with the number of participants for each day of the survey.

Now the survey is closed, we are providing the anonymized, raw dataset. Future (curated) versions of the dataset will be published here too.


We provide the survey questionnaire in several formats, and the dataset with the answers, in anonymized form, in several formats too. The dataset is versioned: current dataset is version 1.0 (raw). Please refer to the changelog file for further details on each dataset version.

Import the survey to your own LimeSurvey install

You can import the survey into your own LimeSurvey environment in order to have full freedom to build upon our work. It's easy, and free software! Follow these instructions:

  1. Download and install LimeSurvey. Right now we are using Version 1.92+ Build 120919, but we have tested the import with most recent version at the time of writing (2.05+) and it works too.
  2. Create a survey, go to the "Import" tab, and import the ".lss" file of our questionnaire.
  3. Activate the survey.
  4. Go the "Responses and Statistics", and generate an (empty) CSV file with the headers for answers to the survey, using the "VV Export" button.
  5. Open the resulting CSV file with your favorite spreadsheet software (e.g. LibreOffice Calc) and copy the two rows containing the headers.
  6. Open the our CSV file containing the answers of the survey with your favorite spreadsheet software (e.g. LibreOffice Calc).
  7. Insert two rows at the top of the spreadsheet and paste the headers you copied from your exported scheme.
  8. Verify that the column order remains the same (the text of the questions is the same in both header rows). If not, reorder the answer columns to match your headers.
  9. Delete the old headers (should be rows 3 and 4), and save the file.
  10. Go again to your LimeSurvey install, "Responses and Statistics", and import the file using the "VV Import" button.
  11. Enjoy!
