Postcode Personality

There's a 
saying that there are three things that matter in 
real estate: "location, location, location."  This was 
funny the first time I heard it, simply because some direct expressions of 
fact are funny when worded in certain ways.  Some 
stand-up comedians make a good living by creating such phrases.  A similar 
construction is found in the 
movie, "
Fight Club," in which the first two 
rules of the club are the same rule, "You do not talk about fight club."[1]
Some 
linguistic sleuthing by 
author and 
journalist, 
William Safire, pinpoints an early occurrence of the location saying to the 
Chicago Tribune, in a 1926 
classified ad.[2]  The wording of the ad suggests that this was a common saying, at least in 
Chicago, at that time.
In any case, it's 
common knowledge that people desire to live in certain areas, and when they move there, they find that their 
neighbors are very similar to themselves.  After my 
wife and I moved to our present 
house, I found that three of the other ten houses on our short street were occupied by people working at my own 
corporate campus.
A recent 
paper in the 
Proceedings of the National Academy of Sciences examines the 
geographical distribution of life 
satisfaction and 
personality traits in the 
London metropolitan area.  It further examines the geographical distribution of the 
correlation between personality traits and life satisfaction.  The 
research was done by an international team of 
scientists from the 
University of Helsinki (Helsinki, Finland), the 
University of Cambridge (Cambridge, United Kingdom), 
Tilburg University (Tilburg, The Netherlands), the 
University of California (Davis, California), and the 
University of Texas (Austin, Texas).[4-5]
The study 
hypothesis, as the paper states, is a person–
environment hypothesis in which a match between a person's personality and the characteristics of his/her neighborhood is important for life satisfaction.[4]  The 
database was the set of 56,019 people in 216 London 
postal districts who participated in the 
BBC Big Personality Test that ran from 2009-2011.[5-6]
The data 
analysis showed significant geographical clustering in satisfaction levels and certain personality traits. It was found that people in central, 
urban areas, were "most open," and, to a lesser degree, the most 
extroverted.  These levels decreased towards the 
suburbs.  The urban areas, aside from their higher 
population density and higher housing 
prices, had higher 
ethnic and 
religious diversity, 
tolerance for 
alternative lifestyles and ideas, but a higher 
crime rate.[5]  I wrote about 
computer modeling of the summer, 2011, 
riots in London in a 
previous article (Modeling Crime, March 13, 2013).
Western Central London was found to be the least agreeable area that had, also, the highest crime rate, the highest housing prices, and the greatest number of 
pedestrians.  As in other studies, it was found that 
emotionally stable and/or extroverted people had the greatest life satisfaction no matter where they lived.  Life satisfaction was high in the 
affluent regions of London.[5]

So, how do people cope in an environment that affords less life satisfaction?  In those areas, people who were most 
agreeable and 
conscientious were better off, suggesting that personality is an important determinant for life satisfaction.[5]  Some key findings,[4-5]
• A person's best place to live depends on the match between his/her dispositions and the characteristics of the neighborhood.
• The strength of the correlation between life satisfaction and personality traits depend on neighborhood characteristics; e.g., a greater openness to experience was more positively associated with life satisfaction in postal districts with greater ethnic diversity.
• In postal districts with a lower level of life satisfaction, greater agreeableness and conscientiousness in individuals were more strongly correlated with life satisfaction.
• The association between emotional stability and extroversion was not modified by neighborhood characteristics.
• Individuals with different personalties derive life satisfaction from different aspects of their environment.[4]

Says 
Markus Jokela, an author of this study from University of Helsinki, Finland,
"It's very common for people to talk about where is the best place to live, but most research has tended to look at factors such as income and low crime rates, and only on a very broad geographical scale, failing to consider individual differences in personality... As a result, studies imply that all people would be equally happy in the same places. It's a one-size-fits-all conclusion that, as we show, is misleading because one's level of happiness is dependent on whether their environment is suited to their personality."[5]
