Biological parents' deaths works in the case of Ellone, and although Squall only lost his mother, his father was in somewhat of a unique situation. I think it can be assumed that everyone else's parents are dead. It would also explained why there are so many unattached teenagers ready to join military academies at relatively young ages. The large populations of Balamb and Galbadia Gardens speaks to a generation of people with no where else to go.
