Note: because of changes in the organizational structure and in definitions of items over time, numbers from previous Campus Profile years are not always comparable to those in the current Profile. This is particularly true of aggregated units such as schools, colleges, academic or administrative totals, or campus totals; when a department moves from one college to another, subsequent versions of the Profile will add the department's ten-year history into the new college history and subtract it from the previous college. Any previous unit selections have been reset to Campus Total due to the possible mismatches mentioned above.
