In analyzing the data from the general social survey on unpaid work, the survey itself and the methodology do provide quite robust estimates on their own. We have, over time, done some analysis at a very high level between the results from the census and the results from the general social survey. There were consistencies, and they do hold together.
However, the analysis itself--the deep and rich analysis, including the high-level aggregates--can be produced through the general social survey. This is what is being recommended, or what is being used, as the primary source for analysis of unpaid work.
