Then that would be the point of the data. At the moment people are acting on claims of differences in pay across a number of sectors and roles and it's way too vague to pinpoint what the actual issue is.

If the data found an actual issue like this, the it would need to be addressed, but at the moment simply claiming that women are paid less doesn't offer any solution apart from paying women an extra 20% across every single job.
