Abstract This study compares the activity spaces of residents in large-scale apartment complexes and low-rise residential areas in Seoul using mobile phone-based mobility data. Four indicators of activity-destination distribution were calculated for 250 m residential grids by gender and age group: mean travel distance, home-destination centroid distance, destination dispersion, and 90 percent kernel density estimation activity-space area. K-means clustering classified activity-space types into five groups at two spatial scales: the metropolitan scale and the neighborhood scale, defined as activity destinations within 1 km of the home grid. The results indicate that residents of apartment-complex-dominant grids had a higher proportion of distant activity-space types than residents of low-rise-dominant grids at the metropolitan scale, whereas they had a higher proportion of home-based activity-space types at the neighborhood scale. Differences by housing type were more pronounced among middle-aged men and older women. Although the effect sizes were modest, the differences were consistent within each spatial scale, while the direction of the differences was reversed between the metropolitan and neighborhood scales. These findings suggest that differences in activity-space composition by housing type vary across spatial scales and cannot be captured by a single measure of travel distance.
