The team at Hackster.io made a huge Maker survey. It is very interesting to discover more information about the people involved in the Maker revolution.
The highlevel info they gather is quite interesting and well worth a look.
One of the interesting detail is that the Maker movement is clearly happening worldwide, in all income categories and to create things of almost any kind… Creativity rules the game. The only sad thing is to realize that women are not well represented… I can only hope that will change (or that the survey missed them).
