More than 40 per cent of neighbourhoods across Greater Sydney now have a majority of renters, making tenants a growing electoral force in NSW.

That’s the conclusion of a report by lobby group the Committee for Sydney which maps how renting is on the rise in the city.

The neighbourhood with the highest share of renters in Sydney was Parramatta-Rosehill (70 per cent) followed by Warwick Farm (67 per cent).

But a swag of inner-city neighbourhoods were also among the ten suburbs with the biggest proportion of renters. They include Redfern-Chippendale (65 per cent), Potts Point-Woolloomooloo (65 per cent) and Pyrmont-Ultimo (64 per cent).
