What are the London postcodes where you’ll be greeted with a smile, and where are the miserable areas where you’re more likely to get an eye-roll?

These questions can be answered after a year-long study into social interaction that has been used to create a 3D map and website called the Happy Forecast.

The research looked at how different areas of the city rank by social activity, with interactive design firm Clubhouse Studios visiting 119 postcode areas three times a day noting interactions between people such as acts of kindness or aggression, body language and verbal exchanges.

The Fulham area was found to be the happiest London postcode to live in – see the lists below to see the other best – and worst- ranking places.

This Is Local London:

Dan Coppock, co-founder of Clubhouse Studios said: "Research shows that sharing the same space for even just a few minutes a day with kind and friendly strangers makes us more optimistic, improves our self-esteem and helps us connect with our environment.

"We undertook this year-long observational study as a general health check for the city's public spaces, and the effect Londoners have on each other as they move through them."

Fellow co-founder Will Orrock added: "We'd like the Happy Forecast to be seen as a playful but informative start in the raising of awareness around how the smallest everyday interactions can make a big difference on our social well-being in London's public spaces."
