Do most Swedes actually collect in pairs?
Of course not. It depends more on whether or not they collect mint or used, and what kind of storage (stock book/pages vs pre-printed album) are they using.
Mint collectors usually try to obtain complete booklets or booklet panes. Used collectors usually go with single specimens, but more advanced collectors hunt down BB/SX-pairs (BB = 3+3 sided pair, SX = pair with two different designs) and booklet panes.
If they use stock books for storage (like most in Scandinavia do), then they start and focus with singles. Pre-printed albums (usually SAFE or Leuchtturm in Sweden) have spaces for pairs and booklets only.
So it's complicated/mixed.
The reason you are seeing more sales ads for pairs and booklet panes/complete booklets comes down to money. Singles are usually worth very little and are sold in bulk (say 1000 different stamps for 20-30$), but pairs and panes easily sell for few bucks a piece.
