The Grapevine project entails an annual compilation of data on state tax support for higher education, including general fund appropriations for universities, colleges, community colleges, and state higher education agencies. Each year states give tax appropriations data for the new fiscal year, and revisions (if any) to data reported one year ago, two years ago, five years ago, and ten years ago. Updated state reports are entered on the Grapevine website as they are received from May through December of the calendar year. Over 30 years of data are available. Visit the Grapevine website.
