Current definitions and views on single living are not quite as precis
e as could be and often such different forms, such as celibacy, single
families, social disinsertion, solitude, are treated as one. This art
icle attempts to rule out some of these inaccuracies by analysing the
combination of two essential components: single living and the importa
nce of the relational network. The main conclusion is to have brought
to light somewhat contradictory processes at the two ends of the socia
l ladder; single living positions itself in very different contexts de
pending on the place it occupies on the social ladder. One of the most
obvious trajectories is that of isolation-exclusion with narrow spher
es of family-type integration as the predominant element, meaning ulti
mate protection, which at the same time penalizes the access to the mo
st operational of social ties.
