Any help much appreciated, thanks.

The government [is] extremely fond of amassing great quantities of
statistics. These are raised to the nth degree, the cube roots are
extracted, and the results are arranged into elaborate and impressive
displays. What must be kept ever in mind, however, is that in every case,
the figures are first put down by a village watchman, and he puts down
anything he damn well pleases. --Sir Josiah Stamp
