Housing Systems Through Time: Trajectories, Accumulation and Uneven Futures

Housing systems are central to contemporary inequality, yet housing inequality is often described through point-in-time outcomes: who owns, who rents, who experiences affordability stress, who accumulates wealth, and who lives with insecurity or poor housing conditions. These outcomes matter, but a snapshot cannot fully explain how housing systems produce unequal futures. Building from housing careers, housing pathways and life-course research, this paper develops a trajectory perspective for analysing housing systems through time. Trajectories are understood as temporal patterns through which households move, remain, accumulate, recover or become constrained. The paper identifies five interrelated features and processes: timing, sequence, accumulation, stability and carry-over. Using Australia as a conceptual illustration, it shows how tenure outcomes can conceal different housing histories, with different implications for security, wealth and future choice. The paper brings these temporal insights together to examine how housing systems shape the opportunities available to households over time.
