A report from the University of Pennsylvania makes use of the most recent national data available from the National Center for Education Statistics (NCES) that can be used to compare all states. It is a tool for assisting states in taking stock of college affordability and identifying the populations and institutions that are most severely affected by declines in affordability.
The report can be accessed at http://www2.gse.upenn.edu/irhe/sites/gse.upenn.edu.irhe/files/Natl_Affordability2016.pdf.
