The assertion that runway excursions are on the rise isn't borne out by the statistics. For many years, they have typically accounted for about one quarter of the (reducing) number of accidents and incidents.
I unfortunately cannot find back the exact figures from a power point presentation, done by the FSF if I remember correctly. But the key message was that they were on the rise this last decade after having been constant. They were now the biggest chunk of the (ppt) cheese. That said it also showed that CFIT decreased dramatically in the same period (due EGWPS) so that might explain the rise too.
As someone once said " only trust the statistics you made yourself"
