 Adding psychological profiles to his previous work , Florida was able to find strong connections between the Big Five personality traits and regions in the United States . For example , neuroticism is concentrated in the New York metropolitan area and the ChiPitts area , agreeableness and conscientiousness in the eastern Sunbelt area , extraversion in the Chicago metropolitan area , the St. Louis / Nashville / Atlanta area , and the South Florida area . Openness seems to be concentrated in the BosWash and the San Francisco Bay Area . Florida explains the results by linking the dominant forms of employment in the areas with the personality traits : manufacturing regions require people who are agreeable ( i.e. , they follow rules ) and conscientious ( they work with dangerous machinery ) , areas with high immigrant populations require that their residents exhibit openness , and management and sales @-@ related jobs need workers with extroversion . Florida was also able to find that his " Gay and Bohemian Index " , which connects gay and artistic communities to high growth and wealth generation areas , is a proxy for regions with large concentrations of the openness personality trait .
