Eli5: Why are bus depots so often in such rough areas of big cities?

Which comes first - is the bus depot built in a rough area because it’s cheap, or does something about it attract shady people?

Whatever it is, in most major cities the area around the major bus/coach station is always a scary place to be at night. What’s the connection?

A bus depot requires a large amount of land, for a business that doesn't make a ton of money, so the land cannot be very expensive. Yet passengers want it to be near the center of the city.

Cheap land near the city center? It's going to be a rough neighborhood, because the nice parts are expensive.
