Harrow has been rated as one of the most miserable places to live in the UK - behind some of the country's poorest neighbourhoods.
Using data from the British Household Panel Survey, a team from the universities of Sheffield and Manchester compiled a list rating the happiness of people in 273 places in the UK.
Shockingly, Harrow came in at a gloomy 253 - making it one of the unhappiest places in Britain.
The survey asked questions including 'Do you feel able to face up to problems?' and 'Have you been feeling unhappy and depressed?' before adding factors such as employment, health and education to make their conclusions.
Some of the places rated above Harrow included neighbouring boroughs Barnet (40), Hillingdon (92) and Brent (157), as well notoriously deprived areas such as Lambeth (100), Glasgow (111) and Salford (166).
The most sparsely populated county in Wales, Powys, topped the happiness list while Scotland's capital Edinburgh was bottom of the pile.
But not everyone is persuaded by the research. Tony McNulty, MP for Harrow East, said: "While people everywhere may be feeling a little unhappy because of the effects of the credit crunch, I don't think people living in Harrow are any more discontent.
"The borough is a vibrant place where people get on well with each other.
"The survey seems totally unreliable to me - for a start, it was carried out by academics in Manchester which, surprise, surprise, has finished second in the research. It's nonsense."
Spokesman for the Harrow branch of Samaritans David (known only by his forename because of the nature of his work) admitted there had been a small surge in calls to the branch, but this was not confined to the borough.
He said: "There has been an increase in calls, emails and drop-ins, but this is down to a number of factors -the credit crunch, the poor summer, Christmas being just round the corner.
"But these things are not specific to Harrow and by no means would I say that people here are unhappier than anywhere else."
However, Dr Dimitris Ballas, who helped conduct the research, defended his work. He said: "There really is something about the intrinsic nature of places which can influence happiness and wellbeing.
"The environment, lack of green spaces, air and noise pollution, crime rates - all of these influence happiness."
But before people rush to leave the borough in search of happiness, he also said that the longer you stay in one place the happier you are likely to get. [
