Yes that looks much more plausible.
Still the population data is quite strange - northern Quebec uninhabited

Instead of just taking nodes into account, I used an awfull* SELECT
count(*) query on osm2pgsql point and line tables.
It means that only nodes with some useful tags are showing up in the green

That seems kind of an understatement - the white areas are quite
puzzeling for example - they are definitely not areas below a certain
node density, easy to see if you compare to

This makes it a very misleading graphic IMO since deliberately leaving
out significant parts of the data will influence many conclusions
people might draw from such a map.
That's what I thought too.
