The NCES has just released its Digest of Education Statistics: 2007 report, which provides statistical information on elementary, secondary, and postsecondary students, faculty, expenditures, and other elements. It includes historical data--in some cases for the last 100+ years--as well as projected data for some elements, such as enrollment and the number of degrees estimated to be conferred. For example, public elementary school enrollment nationwide (pre-K through grade 8) is projected to increase by 10% between 2007 and 2016, while public secondary school enrollment (grades 9 through 12) is projected to increase by 2% during the same time frame. The full report can be found at http://nces.ed.gov/programs/digest/d07/.
