I have to make a poster based on a current public concern. Any ideas on what public concern to use?

My poster has to have some sort of statistic. I was throwing around the topics of school drop outs, health care, homeless, or something about the economy. If you have any ideas please keep in mind my topic cant be too controversial (nothing about abortion, religion or anything of that nature) My teacher also wants us to "think out side the box" so the more creative the better!!!! Thanks!!!!
