New figures show that despite Harrow's low crime rate, people living in the borough are not as happy and relaxed as they could be.

Using data from the BBC’s Big Personality Test - which gathered a sample of 590,000 people between 2009 and 2011 – a Cambridge University study analysed how personality and life satisfaction differed according to postcodes.

In the study published in the journal Proceedings of the National Academy of Sciences this week, maps created by the research team show clustering of each analysed trait with red suggesting high levels and blue showing low levels.

Results show that people living in Harrow are least open to new experiences, along with also having the least extrovert personalities and lower emotional stability.

And despite Harrow having the lowest crime in London last month, life satisfaction in the borough is also largely on the lower side, although homes tend to be more agreeable than their central London counterparts.

In areas that showed lower life satisfaction overall, researchers found that those individuals who displayed the most agreeable and conscientious traits tended to show higher than average satisfaction levels.

Dr Jason Rentfrow, a Fellow of Fitzwilliam College at the University of Cambridge, said: “Together, these findings not only add to our understanding of the ways in which features of our personalities relate to our physical environments, but they also provide potentially useful information for choosing a place to live.

“Making the decision that fits with your personality could have an effect on your overall life satisfaction.”
