Personality world map

The personality test consists of 50 questions and is based on

BIG-5. The Big Five personality traits is a suggested grouping for personality traits. The theory identifies five factors:

Extraversion (outgoing/energetic vs. solitary/reserved)
Agreeableness (friendly/compassionate vs. critical/rational)
Openness to experience (inventive/curious vs. consistent/cautious)
Conscientiousness (efficient/organized vs. extravagant/careless)
Neuroticism (sensitive/nervous vs. resilient/confident)

The dataset contains responses from many countries across the world. I decided to create a map that shows the personality profiles of different countries. The differences between countries are small. If you pick a random person from the country with the lowest neuroticism-score, the Netherlands, and a random person from the country with the highest neuroticism-score, Greece, there is a

36 % chance Greece and the Netherlands neuroticism scores as overlapping distributions. Note how much of an overlap there is.

that the person from the Netherlands will have the highest neuroticism-score.

After cleaning the dataset there were more than 600,000 responses left. The responses were used as a norm and based on this

Z-scores The z-score is the number of standard deviations by which the value of a raw score (i.e., an observed value or data point) is above or below the mean value of what is being observed or measured.

Raw scores above the mean have positive standard scores, while those below the mean have negative standard scores.
It is calculated by subtracting the population mean from an individual raw score and then dividing the difference by the population standard deviation.

were created for each country. Z-scores were kept for each country that had at least 200 responses, 83 countries in total. Around 50% of the responses were from the USA, therefore the norm is heavily influenced by the USA. I created the option to view the scores of each country based on a non-USA norm. This option can be selected in the bottom left of the visualization.

A short note on uncertainty: The data is based on a free test from the internet, I don't have any data on demographics so I don’t know the representativeness of the data. Therefore the results should be interpreted with caution. Also this has been a 1-man-project so there might be mistakes.
