Also worth mentioning is the actual FOI question, which asks for 'a count of sexual offences by taxi and PVH drivers'.
Personally, I'd have also included the term 'hackney carriage', and spelt out the words 'private hire driver' rather than use PHV
And it's not clear precisely how they carry out the search for these things, but no sign that they used terms like hackney carriage or private hire.
On the other hand, they do seem to have included 'Uber'.
Of course, it's likely that police would record most offences like this simply under 'taxi', and to that extent all of them would be picked up.
Also, they seem to have used the (very) generic term 'driver' for search purposes, so that might be too broad
But shows the importance of getting the terminololgy bang on for recording purposes. And also shows the importance of using the right search criteria for actually finding recorded offences
But, like the numbers themselves, without knowing precisely how these thing are recorded, and how the FOI is conducted in terms of data search and interrogation, it's difficult to asses precisely how accurate the data might be...
