title_body: Which types of conlangs are the most popular to construct? For example, can it be shown that there are more auxiliary than artistic conlangs? Note that I'm not talking about use, but about which type is more popular to create. The answer can address any level of specificity; i.e. it could address types, subtypes, very broad generalizations, etc. (I'm afraid I don't know very specific categorizations to be more clear; feel free to edit or suggest better words in the comments.) I would prefer answers focused on conlangs from more "modern" times; say, starting with the introduction of Tolkien's languages forward.
  
  If no answer is possible because the data doesn't exist or isn't organized in a way that allows for such an inventory to be taken, that is also acceptable.
upvoted_answer: My experiences are largely the same as those of Adarain, though I have access to a data-set that perhaps better shows the predominance of artlangs, as I moderate a moderately sized discord server in which users can request roles that show what kind of languages they make and at the same time get a fancy-coloured name. Many users have more than one roles and the roles are not mutually exclusive either. The first number is the amount of people who have the role, the second number is the amount of people who have it as their primary colour:
  
  
  A posteriori: 24, 8
  A priori: 73, 19
  Artistic: 66, 43
  Auxiliary: 11, 8
  Engineered: 16, 16
  Joke: 8, 4
  Secret (for secret communication): 12, 4
  
  
  These numbers clearly show the dominance of a priori artistic languages. Additionally, all but one of the people with auxiliary as their main colour are relative beginners, though this a rather small sample and it may come down to server culture as much as anything.
