Readers may be aware that one of my projects is to archive all of the travel surveys (which typically include one day travel/activity diaries) ever conducted in the United States (as part of the Metropolitan Travel Survey Archive), and that I have used those surveys for studies of time use. Today my wife got a call from the Bureau of the Census about her Time Use yesterday. Since this was an unprompted recall based survey, it wound up being relayed to the survey-taker in approximately reverse chronological order. This follows on my experience last year and this as part of the Bureau of Labor Statistics monthly employment and hours worked surveys.
The surveyor has become the surveyed.
