Theme B: Creating a livable, healthy and environmentally viable citiesAn analysis, which was conducted with residents’ occupancy time and floor areacontrolled, found that, in the category of children’s safety, there was no significantdifference between super high-rise mixed-use housing and ordinary multi-familyhousing. This suggests that residents’ satisfaction with children’s safety isinfluenced by the floor area of their residences, and this issue is related tochildren’s age in households with smaller floor area. However, these results aresignificant in that, with regard to their satisfaction with their children’s safety,residents in super high-rise mixed-use housing, which are exposed to relativelypoor external environments and are located in commercial areas, showed littledifference with those in ordinary multi-family housing.Table 7.
