So, in math class, we were given an assignment regarding graphs. Everyone is to pick a hobby and research it and make a simple graph. I picked publishing numbers of YA versus Adult fiction. I asked on Twitter for some help but got no takers...so can anyone point me in the right research direction? I was thinking about trying the website for a major publishing house but not sure where I'd begin to look there. I just want to know what the numbers are as far the last five years: how much YA is out there and how much Adult? I know YA is big right now, so that's what triggered my thinking here.
Any help would be greatly appreciated!
