Notes:
1) Students having multiple majors are counted once in each major; therefore the sum of
the headcounts in this table will not equal the unduplicated headcounts for the school.
2) Unaffiliated students are former Undecided/Undeclared students who have been assigned
to this school for academic jurisdiction purposes only. Assignments are usually made at
the end of the first year at UCI, based on students' interests.
3) Undeclared students are students who know they want to major in this school, have been
admitted to this school, but have not yet declared a major within the school.
