<p>At least in my country, address is tied to lot parcels and not to individual buildings.</p>
<p>And since we dont have parcel data, we add housenumber as nodes.</p>

Some people put the house number on a node located where there
is the building entrace ( and sometimes forgot to tag the
entrance)<br>
Sometimes there are several house number on big buildings so
house number is place on nodes instead of buildings.<br>
Some people prefer to place the number where it is located
physically, near the street when an house has a long alley<br>
A lot of buildings outside cities does not have house number
appearing in cadastre.<br>
This kind of reason can explain what you are observing....<br>

Just so there is no misunderstanding: even taking address tagged
nodes in to account, the addresses / houses ratio is lower and at
best not different than in other countries without countrywide
access to cadastre-like sources. 3% with nodes, 0.6% without,
comparision CH: 18% / 12%. The numbers are from the respective
taginfo instances.<br>
<br>
So the question remains why the information in not being added to
the outlines.<br>
