Question: has your dependent lived with you the entire year? My daughter lives on campus, but we pay for her housing. Does that count as living with us?

Yes, time spent away for educational purposes is considered a temporary absence and you can still count that time as living with you.  

IRS Pub 501 (page 14):  Temporary absences. Your child is considered to have lived with you during periods of time when one of you, or both, are temporarily absent due to special circumstances such as: Illness, Education, Business, Vacation, Military service, or Detention in a juvenile facility.
