I would infer that it's a large number of absentee parents, either working multiple jobs, or drug-addicted, in prison, etc. Why that leads to suicide I don't know, but teens don't generally have a great sense of the long term. If their future looks bleak now, they don't have the life experience to understand that "now" is temporary and circumstances can and often do change and work out OK in the longer term.
