Abstract: | Most population data are collected and tabulated in an aggregate form by censuses around the world in which political and economic considerations determine the geographic unit of the aggregation. Large spatial variation in population size among, units can limit comparative analysis among different subregions. Census population counts are often used as the denominator in rate calculations. This paper proposes the design of new districts for Australian metropolitan areas that will decrease the absolute range in population among districts. The transport algorithm is used for aggregation of Collection Districts in order to achieve this goal. The transport algorithm proved efficient in assigning CDs to a more equitable alignment of population in the selected Statistical Divisions. This method affords the spatial comparison of city settlement and socio-economic variables as well as deriving a stable denominator for these comparisons. The results demonstrate the advantages of equalized population denominators over those associated with the current statistical districts. |
