Disparities in social advantage within Sydney suburbs have been revealed by data that shows a pocket of about 80 households in the northern suburb of Frenchs Forest is the city’s most well-off locality.

Six of the 10 most advantaged suburban enclaves are located in the city’s north-west, but none are in the east, the Australian Bureau of Statistics new Index of Household Advantage and Disadvantage (IHAD) shows.

The second most advantaged neighbourhood was a cluster of just over 100 homes not far from Taronga Zoo within the harbourside suburb of Mosman.
