Reinterpreting Behaviour–Space Mismatch and Shifting Demand for Flexible Housing in South Korea's Compact Dwellings

This dataset supports the manuscript entitled “Reinterpreting Behaviour-Space Mismatch and Shifting Demand for Flexible Housing in South Korea's Compact Dwelling”. It contains processed national time-use data derived from KOSIS statistics for 1999–2024 and anonymized survey data collected from 500 urban residents in South Korea. The dataset was used to examine changes in in-home activities, construct the Behaviour–Space Mismatch Index (BSMI), analyze flexible-housing demand, and identify resident clusters with different spatial needs and technology acceptance patterns.
