This study examines the nature of the day-to-day variability of individual activity space in Seri Iskandar Malaysia using simple regression analysis. The results show that individuals' time allocation to undertake in-home and out-of-home mandatory activities, household income, access to motorised mode, commute distance and perceived accessibility from home to some basic amenities significantly associate with the spread of individuals' out-of-home activity locations. However, time spent for performing in-home and out-of-home activities, number of trips, and commute distance associate with how far individuals' out-of-home activity locations from their home is. Longer time-use to undertake in-home and out-of-home activities negatively correlate with the spread of out-of-home activity locations, whereas commitments to undertake out-of-home discretionary activities will be conducted near a home base location. When someone is from richer household, he/she will visit out-of-home activity locations farther from his/her home and more spread out. When someone resides within an area farther from government office areas, he/she will have more spread out activity locations. © 2020 IOP Publishing Ltd. All rights reserved.
