This dataset contains Individual Questionnaires (IQ1, IQ2 and IQ3) completed at home by fieldworkers.
The database doesn't allow the completion of more than one IQ1, one IQ2 and one IQ3 per individual.
According to the protocol, an IQ3 should be completed only if an IQ2 has been previously completed. However, there are few cases of individuals having completed an IQ3 without having completed an IQ2.
Also, an individual should normally complete a maximum of one IQ per calendar round, but some individuals have completed two IQs during the same calendar round (at different dates).
Finally, although definition of logical rounds is based on IQ completion, there are some inconsistencies between logical rounds as recorded in the individuals file and completion of IQs.
IQ1 and IQ3 are identical (they have the same questionnaire), while IQ2 is a shorter questionnaire with specific questions.
