And just a further note on this.
As mentioned on the wiki the script that calculates the numbers
tries to reassign object types from "none" to whatever it is in
OSM if it can be found. This has worked well in the past, but it
seems that in the new data not only were 27'000 object reassigned
from "none" to "area", it seems as if this was simply a global
search and replace.
Example http://qa.poole.ch/ch-roads/allroads/2152.html in which
essentially all of the object should have been set to "road" and
not "area".

I've now run the stats with roads that have no associated addresses removed. This looks substantially better, the total number of objects in the GWR has gone slightly down because obviously the issue even existed in the old data just not as bad. To make things easier to understand the per municipality numbers http://qa.poole.ch/ch-roads/ "all" link now actually contains all objects indicating if they were removed because of the filtering, as you will see from the data it seems to be a bit of a per canton by canton issue. GWR OSM (matched) 2017 2019 2019 Corrected Streets 125'781 158'272 131'299 107'962 Points 2'374 1'918 1'615 N/A Areas 25'025 55'079 47'883 N/A None 34'700 7'989 4'880 N/A Total 187'880 223'258 185'677 131'116 (+ 3'855 with minor spelling differences) See https://wiki.openstreetmap.org/wiki/OSM_-_GWR_Street_and_Place_Names_Comparison for explanations.
