so you’d expect to see fewer cases the further south go. I wonder how that holds up?

  You would need to be careful about comparing areas that are otherwise similar or do something more sophisticated than merely comparing rates of psychiatric hospitalization between two areas. Average incomes and other factors are probably important too.

  Many homeless/sick move south so rates between regions may be affected.

  I'd say there are too many factors to guess. People sitting inside all day in offices and when people get home. Driving everywhere so barely outside at all only briefly. Various levels of skin pigmentation each would block various amounts of sun especially in northern latitudes. Clothing style covering more to block sun exposure to prevent skin damage or prevent skin cancer, or after a skin cancer diagnosis.
