A viral map sketched by an Israel-based journalist that draws a banana-shaped corridor through London does capture many of the capital’s most advantaged neighbourhoods, but data across housing, health, education, deprivation, transport and crime show a more mixed picture than the crude online claim.

The map, posted last week on X by Tel Aviv-based religious scholar Saul Sadka, drew rapid comment after he wrote: "As long as you stay within the Banana, you'll have a great time in London. Almost everything outside the Banana is horrible these days, best avoid." The post has been viewed more than 10 million times and prompted news organisations to test the observation against official statistics.

Housing costs are among the most striking differences. Using Land Registry figures overlaid on the drawn boundary, the highest median prices cluster inside the banana. The most expensive neighbourhood by the analysis was Hampstead Garden Suburb, north of Hampstead Heath, with a reported median house price of £8.68 million. All ten communities with the lowest average prices fell outside the banana, located across boroughs such as Ealing, Newham, Hackney, Hillingdon and Croydon. Analysts noted, however, that prices outside the banana have been rising quickly, which could make properties there comparatively attractive for some buyers.

Health measures from the 2021 Census also showed a clear divide in many parts of the city. The banana corridor contains numerous areas with high percentages of adults reporting very good health. The single highest-scoring small neighbourhood — one of London’s around 5,000 Lower Super Output Areas, each home to roughly 2,000 people — was a pocket of Hackney between South Tottenham and Stamford Hill, where more than three-quarters of adults reported very good health. A neighbouring area of Haringey also ranked highly; both areas are noted for large Orthodox Jewish populations.

School attainment followed a similar pattern. Ofqual data for 2024, analysed by constituency, showed the strongest GCSE performance in core subjects clustered within the banana. Schools in the Richmond Park constituency achieved more than 92 percent of maths and English grades at least a pass (grades 9 to 4), followed by Hammersmith and Chiswick at about 90 percent and Chipping Barnet at 89 percent. The lowest results by the same measure were in Croydon East and Dagenham and Rainham, each around 69 percent — neither constituency sits within the banana.

Deprivation statistics complicate the picture. One of the least deprived small areas in London was identified in central Stratford (Newham 039D), where 78.5 percent of households were not classed as deprived in any measured dimension. Other pockets with low deprivation generally fall within the banana, including parts of Barnes in Richmond and Eaton Square in Belgravia. Conversely, one of the highest concentrations of deprivation was recorded in Lisson Green, behind affluent Marylebone in Westminster, where only 17.2 percent of households were not deprived.

Transport connectivity is another factor favouring the banana. Central sections of the corridor are well served by Underground and rail lines, reflecting the inclusion of Westminster, Camden and major business and tourist nodes. Some parts of south-west London inside the banana, notably Wandsworth, have separately raised concerns in recent years about relatively fewer direct rail connections compared with other southern suburbs.

Crime statistics show a weaker picture for some banana neighbourhoods. Central areas in the boroughs of Westminster, the City of London, Southwark and Camden recorded some of the highest crime rates in the capital, even as other parts of the corridor — including Barnet and Richmond — registered lower rates than neighbouring districts outside the banana. One of the lowest recorded crime rates in the capital was in Berrylands, Kingston upon Thames 010A, at fewer than five crimes per 1,000 residents in the year to June.

Several areas outside the banana buck the broader trends. Hackney, historically one of London’s most deprived boroughs, has undergone substantial change: gentrified pockets now show high school attainment, strong health markers and rising property values. The analysis noted that some affluent enclaves — Notting Hill, Maida Vale, Greenwich, Chiswick, Ealing and the South London suburb of Dulwich — sit outside the banana despite their wealth and amenities.

Sadka told followers he used official house price and crime figures broken down by postcode sector to create what he described as a "minimal-effort, tongue-in-cheek" map intended to provoke debate among English residents. The post’s reach and the subsequent data-led scrutiny underline how discussions about London’s geography and inequality now play out across social platforms and news outlets.

Taken together, the data do not support an absolute rule that living inside the banana guarantees a better life, but they do show that many of the city’s most expensive properties, higher educational outcomes and certain health and deprivation advantages are concentrated along the corridor. At the same time, rising prices and pockets of strong social indicators outside the banana — and higher crime in some central banana areas — demonstrate the limits of a single, sweeping boundary to capture the capital’s complex social and economic geography.
