Not sure why people are debating LDRs, disputing 10 or 15 knot airframe certifications or some belief that the -800 is susceptible to overruns?
They are disproportionately represented in over-runs, and will be just because the the numerical number of takeoffs and landings they do, compared to almost every aircraft except the A32x.
The more interesting question is the
relative rate of A32x vs B737-NG runway excursions. Eyeballing, wikipedia says about 7,900 A32x deliveries vs about 7000 B737-NG, so a very large sample size for both to make valid comparisons.
My understanding is the -800 is also significantly faster across the fence compared to the A32x, and even the 737-classic, so that would provide and extra margin for pilot error in the decision to land/go-around for deep landings and floats on marginal runways.
