We categorize them in our office when the complaints come in, but they are imprecise. For instance, a journalist could make a request without disclosing that they're from the news media, so we would probably qualify that as an individual or a member of the public because we wouldn't know. Or you could have somebody who is an academic but doesn't report that, so we would count them as a member of the public. A company may make a request or a complaint via a law firm, for instance, and we would consider that a business.
It's very imprecise the way it's done. We do it on the basis of the information we have when we receive the complaint, and I think it's the same in the institution.
