A rising SEIFA decile over successive Censuses is one of the clearest signals of gentrification. It captures the demographic shift in who lives in a suburb rather than just what they are paying for housing. If Woollahra has moved up a decile or more between the 2016 and 2021 Censuses, it is undergoing the kind of socio-economic transition that has historically accompanied above-average capital growth in Sydney.
