One in three households is a single person
33.6 % of households in Roda de Berà are one person, against a 22.6 % median. It reads like a census figure and it is one of the things that most changes a lockout: living alone means nobody inside can open from the other side and nobody nearby has your spare, so a door closing behind you goes from nuisance to standing in the street. It is also the profile that gains most from leaving a copy with someone you trust — which costs nothing and saves the callout.
