“I’d always wanted to move out of home and I’d always felt ready,” says Ida Staberg, who has been renting an apartment by herself in Vällingby, a suburb north-west of Stockholm, for two years, since she was 19. More than half of Swedish households are single-person, the highest proportion in the EU, according to Eurostat. Official figures given to the BBC by the Swedish government’s number-crunching agency Statistics Sweden suggest that includes around one in five 18- to 25-year-olds, although its researchers estimate that the real number could be higher, since many remain registered at their parents’ address while they stay in sublet rentals.
