Number formatting

I would double check your consistency with displaying percentages. In the rows for the demographic info I think everything is presented as x%, but another option that wasn't the case. It was just 0 instead of 0%. Additionally, for large figures, like the institutions revenue, I would probably format that to 1.3 billion, or at least add commas. Any number > hundreds I would add commas and for really large numbers change it to 1.3 billion.
