HOUSEHOLDS in the most affluent areas of Croydon earn up to three times as much on average than those in the poorest parts of the borough.
Figures for the total median annual household income in Croydon also show the stark contrast between the north and south of Croydon.
Those differences - in health, politics, education and living standards - are well documented.
But the map below, created by the Advertiser, sheds new light on the gulf in earnings between certain sections of the town.
Croydon's highest earners live on the exclusive Webb Estate in Woodcote, with households there earning an average of £61,490.
In contrast, people living in the area of New Addington around Dunsfold Way and Castle Hill Avenue earn the least, with an average total income of £18,572.
Put another way, it would take a family in Dunsfold Way 806 years to earn Manchester United stay Wayne Rooney's annual wage, according to the BBC's online calculator.
The median income in the UK at the time the statistics were compiled was £21,326.
