Additionally, the report explores the relationships between income levels, family events, and the size and selected neighborhood qualities of the moved-to dwellings. The analysis is based on Norwegian registry data for the period 2005–2023. Key findings of the report include:

  • Over 10 million moves occurred in Norway during the period, involving individuals aged 19–69. Approximately one-third of these moves were linked to union formation, union dissolution, childbirth, or "empty nest" situations.
  • Most family-related moves within urban areas occurred inside the same municipality.
  • Union formation was the most common reason for family-related moves, comprising about 15% of urban moves in 2023, compared to 13% elsewhere in Norway.
  • Nearly one in ten moves in Oslo, Bergen, and Trondheim in 2023 were linked to union dissolutions, compared to 8% in Stavanger and other parts of Norway.
  • The proportion of childbirth-related moves decreased over time, making it the third most common family-related reason in 2023, representing 4–5% of moves.
  • Among individuals aged 50–69, union dissolution was the most common reason for moving, followed by new unions. Childbirths were a more frequent cause among those in their 30s.
  • Nearly 5% of moves among individuals aged 50+ occurred the same year their adult children moved out.
  • Households moving due to childbirth or "empty nest" situations had the highest incomes.
  • Moves for union formation and particularly childbirth resulted in the largest homes, while those moving due to union dissolutions or "empty nest" situations gained the most space per person in their new homes.
  • Family-related moves out of urban areas generally led to larger homes.
  • Moves within urban areas improved access to everyday infrastructure (e.g., daycares, public transport), while moves out of cities provided better access to nature, recreational areas, and lower pollution and noise levels.
  • Family-related movers in Oslo benefited from the best access to cultural amenities in their new neighborhoods, although these areas also had higher pollution levels.
  • Family movers with higher incomes secured larger homes and better access to nature and recreational areas, especially in Bergen and Trondheim. In Oslo, high-income moves were often to less polluted areas, while lower-income movers had better access to everyday infrastructure.
  • Overall, moves associated with new unions and childbirths typically led to homes with better neighborhood qualities. Both family events and income influence housing and neighborhood choices, with some geographical variations in key indicators.
