Generally, no. We did look at the public service as a whole and how well distributed the responses were, and we saw no what would we call “risk of bias” in the data.
You would have a problem, to use an extreme example, where no women answered the survey and it was all done by men. You would only get the perceptions of men. You wouldn't get the perceptions of the whole of the public service.
We did not find that. We found our response to the survey to be proportional to what we knew were the characteristics of the public service.
