So you're curious about the data behind this app. Here's one more little tidbit for you:
  • The median for K-12 spending per county per student is $9,694.26.
The data behind this app was manually gathered from Excel spreadsheets available on the California Department of Finance website. K-12 Enrollment numbers and Community College numbers are from 2004-2005 unless otherwise noted. As far as I can tell, this is the most recent data. If you know of more recent data, or would just like to chat about the app, please contact me. Thanks for looking!
