Percentages are estimates and do not sum to exactly 100% due to rounding. Distributions vary by country, test version and sample. Self-selected online tests tend to over-represent Intuitive and Feeling types compared with these figures.

The Four Dimensions

Each type is a combination of four either-or preferences. On their own, these split the population like this.

The Introversion / Extraversion split is nearly even, while Sensing outnumbers Intuition almost 3 to 1, which is why abstract, big-picture thinkers often feel outnumbered in everyday settings.

Common Questions

What is the rarest personality type?
INFJ is the rarest, at about 1.5% of the population. The next rarest are INTJ (2.1%), ENTJ (2.7%) and ENTP (3.2%). All four share the Intuition preference.
What is the most common personality type?
ISFJ is the most common at roughly 13.8%, followed by ESFJ (12.0%) and ISTJ (11.6%). The four most common types together make up almost half of all people.
What percentage of the population is ENTP?
ENTP is about 3.2% of the population, one of the rarer types. It is more common in men (around 4.0%) than in women (around 2.4%).
Why do the percentages differ from other sites?
Frequencies shift with the country, the test version and how the test was taken. Voluntary online tests pull in more Intuitive and Feeling types, while large general-population studies, like the figures here, show Sensing types at roughly 73%. Treat any single number as an estimate, not a fixed fact.
Does a rare type make me special?
No. Rarity is a frequency count, not a value judgement. A common type is no less capable or complex than a rare one. The data is interesting because it explains why some people feel understood by almost everyone and others rarely meet someone who thinks the way they do.
