Migration at older ages is commonly explained by reference to the search for greater amenity, and subsequently by the onset of greater dependency, but the links between mobility and specific life course transitions have rarely been articulated. We aim to establish the timing of migration in relation to retirement from the labour force, and to determine how its intensity varies around the retirement event. We also seek to identify how household and individual characteristics shape the propensity and timing of migration, differentiating moves according to distance and with particular attention to the characteristics of the spouse. Data are drawn from the first six waves of the Household, Income and Labour Dynamics in Australia survey, a nationally representative panel study covering the period 2001–2006. Migration events are identified relative to retirement and event history methods are employed to establish the characteristics predisposing households to relocate around retirement. Results demonstrate that retirement acts as a trigger to migration but the propensity to move falls as retirement age rises and the hazard is increasingly concentrated in the year retirement occurs. Within this framework the presence, health, education and retirement status of a spouse exert a significant influence on the likelihood of migration, though with different effects for long and short distance moves. Results highlight the importance of variations in underlying life-course trajectories in shaping retirement migration and demonstrate that only a minority of moves at ages 55–69 are directly associated with retirement, underlining the need for caution when identifying retirement migration using age as a proxy measure.
