This study examines two factors affecting children's school journeys – independent mobility and accessible school opportunities. Two time-geography based indicators, the spatial extent of potential path area and the number of weighted school places reachable (labelled OPP), are estimated. Multi-level modelling has been developed to analyse the interplay of individual, household and neighbourhood factors. Hong Kong is used as a case study because the neighbourhood effects on school provision within compact cities have not been well studied. The results show that 30.4% of the children's school journeys were made without adult companions. Half of the children walked to schools. The multi-level analysis suggests that nearly 90% of the variance in both indicators was found at the individual level. Neighbourhood, though not a decisive factor, does have impacts on the number of accessible school choices. Copyright of Children's Geographies is the property of Routledge.
