The suburb spans approximately 3.1 square kilometres and recorded a population of 6,913 at the 2021 census, indicating moderate growth since the 2016 census. Residents have a median age of 35 years, reflecting a slightly younger profile than the NSW average.
Households average three residents, with about 1.8 vehicles per dwelling. Families number around 1,700, each typically consisting of one or two children, and married couples account for over half of the adults.
Weekly median household income sits at $1,793, while median rent is $450 per week, and median mortgage repayment is about $2,260 monthly. Approximately 38.6 per cent of dwellings are rented, with 34.2 per cent mortgaged and 23.6 per cent owned outright.
Public transport relies mainly on the Liverpool–Parramatta T‑way bus route, as South Wentworthville lacks a train station. Cyclists and pedestrians benefit from access to the M4 cycleway, which terminates in the suburb and links to broader Western Sydney paths. Commuters primarily drive or use buses, with about 60 per cent travelling by private vehicle and a smaller proportion taking public transport or working from home.
Essential services are available in the adjacent areas of Wentworthville and Merrylands, offering supermarkets, cafés, medical clinics, childcare facilities, and educational services. The nearby Wentworthville station provides train access to Parramatta and the city centre.

Its suburban streetscapes rely on bus and cycleway links, with neighbouring centres supplying shopping and community infrastructure. Green transport corridors, parks nearby, and a solid demographic structure shape this quietly evolving Western Sydney suburb.
