This Tube map shows which areas of London are affordable if you make an average income

A new version of the London Underground map, created by homelessness charity Shelter, redraws the traditional fare zones to show which areas are affordable if you make an average income.

Shelter map is divided into three zones - affordable, difficult to afford, and unaffordable - based on an average full-time income in London of £34,320.

Here's an explanation of the categories:

Affordable: the average cost of a two-bed private rental property is less than 35% of the combined take home pay of a two-wage household (one person working full-time, one working part-time) on an average salary.

Difficult to afford: the average cost of a two-bed private rental property is between 35% and 50% of the combined take home pay of a two-wage household (one person working full-time, one working part-time) on an average salary.

Unaffordable: the average cost of a two-bed private rental property is more than 50% of the combined take home pay of a two-wage household (one person working full-time, one working part-time) on an average salary.

Unaffordable

The majority of the network is categorised as "unaffordable," with 171 stations wiped off the map.

This is what central London looks like:

Difficult to Afford

The "difficult to afford" category covers clusters of stations situated in outer London, near residential areas in the north and northeast of the city.

This means that anybody hoping to rent private property in areas like West Ham, for example, will likely have to sacrifice between 35% and 50% of their salary.

Affordable

Out of the 27o stations on London's underground network, just 15 are considered to be in affordable areas: Chesham, Amersham, Chalfont & Latimer, Watford, Epping, Theydon Bois, Debden, Loughton, Buckhurst Hill, Roding Valley, Chigwell, Elm Park, Hornchurch, Upminster Bridge, and Upminster.

"Affordable" stations, which exist on the outer-reaches of the Tube network, account for no more than 6% of entire system.

Shelter

In December, a YouGov poll commissioned by estate agents Knight Frank showed that a third of Londoners were willing to spend 50% of their salary on rent. Shelter's map suggests 50% is the least you should expect to pay if you want to rent property anywhere in fare zone 1 and the majority of fare zone 2.

"The idea behind this map is to highlight the scale of the problem by closing stations in areas no longer affordable to the average renter," a Shelter spokeswoman said in an emailed statement.

Shelter is campaigning to put pressure on the next mayor of London to fix it what it describes as a renting crisis. Front-runners Zac Goldsmith and Sadiq Khan have both prioritised the cost of renting in London as major issues in their manifestos.
