I wonder if respondents were allowed to check more than one item on that list when answering the question? If so, there is likely a lot of double counting. Large, overarching surveys are quite difficult to create and interpret. The Django survey I quoted earlier was a worldwide survey for what it's worth.
> I wonder if respondents were allowed to check more than one item
yes, you are right, they definitely were allowed to check more than one item, we can see that the total sum of all options gives us a total of more than 100%, so that must have been the case.
But even then, it's hard to overlook the fact that the first three options in the list are related to web development, and with quite high percentages.
