Returns aggregated resident demographics for the BRF: total resident count, median age, median förvärvsinkomst (when ResidentCount ≥ 20 of adults), and a per-bucket breakdown by age band × gender. Cells with fewer than 5 residents are suppressed for k-anonymity. Numbers refer to all current residents folkbokförda at the BRF’s addresses; income is computed over the 18+ subset.
