Concerned About vs. Concerned With
Concerned About vs. Concerned With separates directly documented constructions and keeps the distinction narrow rather than turning a context-sensitive pattern into a universal preposition rule.
Use “concerned about” for worry or concern; use “concerned with” when something is interested in, focused on, or dealing with a subject.
