New Yorkers are neurotic and unfriendly, says Cambridge University 'personality map'

New York is home to the most neurotic and unfriendly people in American while North Dakota is where the nicest people live, according to a Cambridge University "personality map" of the USA.

Researchers created the first ever map of its kind is based on the results of a six year online survey of 620,000 people.

They claim it reveals how certain types of people are more likely to live and flourish in different parts of the country and showed links between personality traits and social phenomenon, like crime rates.

Personality traits: Anxious, stressful and impulsive.

Highest-scoring states: West Virginia, Rhode Island, New York, Mississippi, New Jersey, Pennsylvania, Kentucky, Louisiana, Ohio, Arkansas.

"What is particularly impressive is that the results show the effects of personality on people's social habits, values and lifestyles are so pronounced that they have an impact on much bigger social forces."
