They say that birds of a feather flock together – so how does your personality fit with the people living nearby? Do you sometimes wish you lived among people who were just a bit more adventurous? Or would you prefer to live in a quieter, more reserved city?

These were the kinds of questions that Wiebke Bleidorn, at the University of California, Davis hoped to answer with her latest research project. Using a vast online survey of more than 500,000 participants, she has profiled 860 cities across the United States of America.

The survey measured the so-called “Big Five” personality traits (emotional stability, extraversion, openness to new experiences, agreeableness, and conscientiousness) using well-established questionnaires developed by other psychologists.
