Seasonal differences in mobility and activity space in later life: a case study of older adults in the Northern...

Mobility is crucial for maintaining well-being in later life. Previous research has shown that older adults' mobility fluctuates throughout the day, with a particular focus on afternoon outdoor movement. This paper takes a broader approach and explores the seasonal differences and similarities in mobility and activity space in later life, using older adults in the Northern Netherlands as a case study. Seventeen older adults participated in the study, for which we used a mixed-methods approach combining GPS-, activity diaries, and in-depth interview data analysed through grounded visualisation. We have collected data from each participant for a week, once during fall/winter and once during summer. The findings of this paper defy common expectations around older adult mobility; for instance, the participants walked less in summer and had a larger activity space in winter. Equally, we demonstrate that it is crucial to distinguish between daily and incidental activity spaces, particularly when factoring in seasonal variations. Yet our mixed-methods approach revealed discrepancies between perceived and measured mobility and activity space. We argue that the intricate interplay of seasonal influences, weather conditions, and personal factors significantly shapes mobility practices in later life, underscoring the need for holistic planning of age-inclusive environments.
