Below is a graph of the spending per pupil in Fairfax County Schools per year since FY 2007. (We'd love to go back further but haven't had time yet. We're a volunteer organization. If you love data and analysis and want to make a difference, then contact us. We welcome your help!)
If you are interested in doing your own analysis we have made this document and supporting data available for download. (Google Spreadsheet, Excel - CSV)
