Why there are not many Rated contests for division 2?

There are many contests going on but only some (very few) have the sentence “Rated for division 2” Why is that so? Am I considering something wrong? There are many contests that do not mention whether they are rated or not.
Please provide some names of the contests which are rated for division 2…

  • Cook-off
  • Lunchtime
  • No more contests

So only once or twice a month???
Cool. Thanks.
