A long planned master post of sources for future reference. First four are the 'general' surveys with many thousands of respondents deriving from tools used to play the game. These are capturing the preferences of players without requiring them to fill out a survey.
The other sources are survey responses, these give more detail of how people are playing the game but are self-selecting. As noted before the preferences of the general population and the survey responding 'enthusiasts' are different.
