Compared to other cities yeah. Those areas are the west side, south end, and east side. Which isn't to say it's the entirety of the east, west, and south of Stamford. There are just areas that haven't gotten investment in decades so they look rundown. My definition of safe is to express you won't have a confrontation if you're in the area. I don't think these areas are great for taking a family stroll, but even with that caveat there's always some park you can walk to that's ideal for that.

For context I've lived in other cities like Boston, New York, Los Angeles and I've visited cities like DC, Baltimore, Nashville, Memphis, New Orleans, Houston, Austin, New Mexico, and some other places up north. There are definitely places I remember feeling scared for my life and Stamford doesn't come anywhere close to that.
