Carshalton consists of a number of neighbourhoods. The main focal point, Carshalton Village, is visually scenic and picturesque. At its centre it has two adjoining ponds, which are overlooked by the Grade II listed All Saints Church on the south side and the Victorian Grove Park on the north side. The Grade II listed Honeywood Museum sits on the west side, a few yards from the water. There are a number of other listed buildings, as well as three conservation areas, including one in the village. In addition to Honeywood Museum, there are several other cultural features in Carshalton, including the Charles Cryer Theatre and an art gallery in Oaks Park. It is also home to the Sutton Ecology Centre, and every year an environmental fair is held in Carshalton Park to the south of the village.
The combined population of the five wards comprising Carshalton was 45,525 at the 2001 census. A majority of the population of Carshalton is in the ABC1 social group. In the 2011 Census the wards had been merged into 3 with a total population of 29,917.
To the south of the area now known as Carshalton, remains of artefacts dating from the Neolithic to the Iron Age have been found, suggesting that this was an early place of habitation. Prior to the Norman Conquest it is recorded that there were five manors in this location owned by five freemen.
