Columbia University has been recognized as one of the safest colleges in America, ranked first on many rankings and surveys for student satisfaction. The environment is safe due to their strong security measures, which includes around-the-clock patrols by police officers who are trained precisely how to deal with issues like sexual assault or other violence that might take place at night when most students will be asleep; this also applies during weekends, so you never have an excuse not check your surroundings because there’s some downtime!
