The University of California was chartered in 1868 and its flagship campus — envisioned as a "City of Learning" — was established at Berkeley, on San Francisco Bay. Today the world's premier public university and a wellspring of innovation, UC Berkeley occupies a 1,232 acre campus with a sylvan 178-acre central core. From this home its academic community makes key contributions to the economic and social well-being of the Bay Area, California, and the nation.  Currently UC Berkeley has 35,843 students as of Fall 2009 including 25,530 undergraduates and 10,313 pursuing graduate degrees.
