A very general, thorough and thought-out work. Well done!
There are *some* flaws in it though.
The charts detailing demographics (specifically education) could use a side-by-side comparison with the world/U.S. percentages, as it stands, some might not know how educated bronies really are.
Personality type percentages would also improve this analysis; I firmly believe that the fact 28% of bronies are INTJ's (Scientists) is relevant to your analysis.
Clopfics probably didn't need a column of it's own (a subgroup of fanfics), however, music probably did. I realize that music is more amorphous and thus harder to detail, but it is still a large part of the fandom; 85% of bronies listen to fan-produced music at least once a week, second only to watching episodes (96%).
*This does not apply to the current hiatus in which no new episodes are being released.*
Giving each of the Mane 6 a personality description is debatable, after all, this is a analysis of Bronies and not the show, but I concede that their personalities are relevant to the fandom. However, the descriptions did not give us much new information, assuming that this was made for Bronies.
All statistical information was obtained and can be obtained from The 2013 State of the Herd Report. [link]
So anyway, nice work, keep it up!
