- Locations: UCD near (20 min) Sacramento and a few hours from Silicon Valley. Small town/rural family friendly laid back community. Highly residential campus.
UCI in large suburban city. Near beaches and within a 1-2 hours of the San Diego tech hub or LA Silicon Beach tech area. Quiet clean campus, but more known as a commuter campus with many students leaving on weekends.
I suggest you consider watching some YouTube videos on Campus life for each school.
On campus costs are comparable, but off-campus housing will be expensive near UCI vs. UCD.
