Most transfers come from California community colleges, as noted in previous posts.
Compared to Indiana, Berkeley has a higher percentage of undergraduates from lower income (Pell grant) backgrounds, and a higher percentage of undergraduates with year-round tans. That may affect the cultural feel of the campus. Fraternity and sorority participation rate is significantly lower at Berkeley than at Indiana.
