Seventy-five percent feel safe downtown compared to 83 percent two years earlier, the survey found.
After dark, only 34 percent feel safe; that figure declined from 44 percent in the 2005 survey.
However, most respondents gave the city high marks for cleanliness, friendly people and cultural attractions.
Sentiment about stress is down. Two years ago, 37 percent said their stress had a negative or extremely negative effect. This year, only 29 percent said stress was a problem.
