The Percentages of the 16 Personalities

It should come as no surprise that the data on how 16 Briggs personality types are distributed is already well established. It is derived from data from the 16 Personalities Foundationthemselves and, in the following article, you will see the curated statistics regarding each type in the United States’ population. For ease of reading, each batch of four personality types is categorized according to the temperament it belongs under. The discovery that these “batches” share similarities among each other, based on their personality preference, can be attributed to David Keirsey, Ph.D, a renowned clinical psychologist, author and professor at California State University, Fullerton.

Before we begin, as a reminder, here are what the personality type letters stand for:

  • Extraversion vs. Introversion (E and I)
  • Sensing vs. Intuition (S and N)
  • Thinking vs. Feeling (T and F)
  • Judging vs. Perceiving (J and P)

As you will see below, people who have the Sensing type, the Feeling type and the Judging type are more frequent than those with the Intuition type, the Thinking type and the Perceiving type. Down below you will find the distribution for the rest of the personality traits. Interestingly enough, both the Introvert and Extrovert nature is evenly distributed across the collected data.

Personality Type Percentages by Gender

Of course, there are some personality differences in the distribution of personality types by gender. Some types have more male representation as opposed to female and vice versa. Sadly, the 16 Personalities Institute doesn’t provide information on this, so we had to use our own data to present the findings.

To supplement our data, we have also turned to another well-known and authoritative study on gender differences and stereotypes. This normative study was conducted in 1996 by Allen Hammer and Wayne Mitchell, and is titled “The Distribution of Personality Types In General Population.” It surveyed 1267 adults on a number of different demographic factors. One of these factors was gender, and its findings can be used to show certain gender trends in temperament preferences in males and females.

Below you will find what we (and they) discovered. This table shows the average distributions of the 16 different personality types by gender.


Rarest Personality Type

Again, according to the 16 Personalities institute, the INFJ personality type is the world’s rarest personality type. This makes sense as this type has Introverted, Intuitive, Feeling and Judging preferences — which makes them quiet and sheltered people, that are very much in tune with people’s feelings. If a person has this combination of preferences, it’s easy to understand why they would prefer to blend in with their environment, rather than stand out, as they are an introvert. There might be more people that share the INFJ personality traits out there – they just may not like to make themselves known to the world.

According to our data, the rarest personality type is ESFJ. A person with this personality type is caring, supportive and is concerned for everyone’s well being and happiness. According to the official 16 personalities data, the ESFJ personality type makes up for 12% of the US population. This difference in statistics may be due to difference in sample size (PMax sampled 6 million people), difference in demographics (PMax has test respondents from different countries, not only from the Unites States) and the fact that people from a certain personality type are more prone to answer surveys, such as the 16 personalities test, compared to others.

Rarest Male Personality Type

Our data shows that the rarest male personality type is INFJ. INFJ men make up only about 0.5% of the total males tested. They are introverted, feeling, gentle and idealistic, but still capable of making decisions and carrying on with their goals. They aren’t static spectators — their belief that good and love will save the world compels them to act. Their superior understanding of people’s emotions makes them very empathic and easy to connect to.

Male Temperament Preferences

According to the Hammer-Mitchell study, 68.6% of men have Thinking personality preferences compared to 38.8% of women. This can explain why INFJ is the rarest type among men. This does not mean that men don’t show any Feeling nature — it simply means that a man, as a stereotype, is more likely to be a Thinking type. It also means that men use the Thinking trait more when it comes to decision-making processes. Even if they are more prone to relying on this preference, it is important to know in which situations it’s important to tune into their Feeling nature. This is a skill worth training.

Rarest Female Personality Type

Our data shows that the rarest female personality type is INTJ. Female INTJs also make up about 0.5% of the total females tested. These ambitious, introverted and bold people are unbothered by the general opinion of the masses and are not afraid to pursue their own philosophy of life. Their strategic nature compels them to avoid the spotlight and to work from the shadows. This is why they can often be seen alone — but they don’t mind this at all. For them, every move they make in life is carefully considered and planned in advance.

Female Temperament Preferences

Similarly to the above statistic, the Hammer-Mitchell study found that 61.2% of women prefer Feeling compared to 31.4% of men. This can explain why a female INTJ is in fact a rare personality type. Again, this does not mean that women are oblivious to the Thinking personality trait, but rather that they have a different type of personality characteristics. A worthy analogy is that we all have two hands, but we might prefer our right one to do things with, rather than our left one. Or we might throw a ball with our right hand but catch it with our left, and vice versa. Again, when it comes to situations that demand a certain decision to be made, it is important to know which preference should take precedence — be it following your gut feeling or what common sense tells you. This is a skill that can be trained through a number of different techniques — emotional intelligence being one, for example.

Other Rare Personality Types

With INFJ being the rarest personality type, what are some other rare personality types? Here are the top 5 of the rarest personalities according to the 16 Personalities Institute:

  • INFJ: 1.5%
  • ENTJ: 1.8%
  • INTJ: 2.1%
  • ENTP: 3.2%
  • INTP: 3.3%

Most Common Personality Type

The most common personality type according to the 16 Personalities Institute is ISFJ, the Defender. This type makes up 13.8% of the US population. This is also not surprising, as they are very logical and traditional people — there is a very big chance you know someone like that in your surroundings. They can be often found in institutions where procedures are key — administration, for example. This personality type is predominantly female — it has only 29% male representation.

According to our data, the most common personality type is INFP. This perceiving type is shy, quiet, feeling and might seem secluded. However, from the inside these people are empathetic, harmonious and maintain rich inner workings. Perhaps the reason why our statistics found that this is the most common personality type is because INFPs are more prone to want to learn more about themselves, hence are more likely to take personality tests such as ours.

Other Common Personality Types

With ISFJ being the most common personality type, what are some other common personality types? Here are the top 5 most common personality types according to the 16 Personalities Institute:
