The city around the clock: space - time patterns of urban ecological structure

The space - time diaries for more than 1500 respondents in Halifax, Canada are used to generate census-like data for spatial units at six different times during the day. A space - time factorial ecology reveals distinctive diurnal patterns in the city's social geography. Aside from illustrating temporal variations in traditional factors, such as status and family orientation, additional factors relating to activity patterns and their social settings are identified.
