How to estimate the number of people who are likely to have the ESTJ personality type based on a given population size

 ISTJ is a personality type defined by the Myers-Briggs Type Indicator (MBTI) that stands for Introverted, Sensing, Thinking, and Judging. While it's not accurate to generalize an entire country's population by personality type, here is a list of countries that have been reported to have a relatively high percentage of individuals with ISTJ personality traits:

  1. Germany
  2. Switzerland
  3. Japan
  4. Norway
  5. Denmark
  6. Canada
  7. Sweden
  8. South Korea
  9. Finland
  10. Belgium

Please note that these are just trends and generalizations and individual variations do exist within each country's population.


Here are some general statistics on the prevalence of ISTJ personality types in the United States and Singapore, which includes Idaho and Singapore, respectively:

  1. In the United States, ISTJ is the third most common personality type, with an estimated 12% of the population having this personality type. This includes the state of Idaho, although it's not possible to determine the exact percentage of ISTJ personality types in Idaho specifically.

  2. In Singapore, according to a 2016 survey, ISTJ was reported as the second most common personality type, with an estimated 19.4% of the population having this personality type. However, it's important to note that this survey was not conducted using the Myers-Briggs Type Indicator and may not be representative of the entire population.

Again, it's important to remember that personality is complex and unique to each individual, so these statistics should be taken with a grain of salt.


List of countries that have been reported to have a relatively high percentage of individuals with ESTJ personality traits:

  1. United States
  2. Ireland
  3. South Africa
  4. United Arab Emirates
  5. Mexico
  6. Israel
  7. Peru
  8. Costa Rica
  9. Panama
  10. Saudi Arabia

Please note that these are just trends and generalizations, and individual variations do exist within each country's population. It's also important to keep in mind that personality type is a complex and multifaceted construct, and it's not possible to make definitive statements about entire populations based on this framework.


Here are some possible thesis statements about the ESTJ personality type with corresponding references:

  1. "ESTJs tend to have a strong work ethic and leadership skills, which can be beneficial in organizational contexts." (Furnham & Crump, 2005; Tziner, Ben Dov, & Haccoun, 2015)

  2. "ESTJs may experience conflict with individuals who have different communication styles, particularly those who value emotional expression over logical analysis." (Myers & McCaulley, 1985; Hammer & Mitchell, 2005)

  3. "ESTJs are likely to excel in fields that require attention to detail and adherence to established protocols, such as law enforcement or military service." (Bridges & Lowery, 2006; Quenk, 2000)

  4. "ESTJs may struggle with adaptability in situations that require flexibility and improvisation, as they tend to prefer structure and routine." (Kaplan, 1997; Hammer, 1993)

  5. "ESTJs may have difficulty recognizing and addressing the emotional needs of others, which can strain personal relationships and hinder their ability to connect with others." (Keirsey & Bates, 1978; Tieger & Barron-Tieger, 2001)

It's possible for individuals with any personality type, including ESTJ, to hold positions as parliamentarians in a country. A person's personality type does not determine their ability to excel in a particular role or profession.

In fact, some might argue that individuals with ESTJ personality traits might excel in parliamentary positions due to their strong leadership and organizational skills, ability to manage complex systems, and focus on achieving goals. They may also be effective in handling administrative tasks and navigating complex political landscapes.

However, it's important to note that a person's personality type is just one factor that may contribute to their success in a particular role. Other factors such as education, experience, and social networks may also play a significant role. Additionally, a diverse range of personality types and perspectives can be beneficial for a parliamentary system to represent and serve the population.

Ultimately, while there is no direct link between a person's personality type and their ability to hold a parliamentary position, individuals with ESTJ traits might bring unique skills and strengths to the role.


Some individuals who are often identified as having ESTJ traits based on their behaviors and characteristics:

  1. Martha Stewart, American businesswoman and television personality
  2. General George S. Patton, American Army officer during World War II
  3. Dwight D. Eisenhower, American Army general and 34th President of the United States
  4. Angela Merkel, German politician and former Chancellor of Germany
  5. Margaret Thatcher, former Prime Minister of the United Kingdom
  6. Alan Greenspan, American economist and former Chairman of the Federal Reserve
  7. Donald Trump, former President of the United States
  8. Judge Judy Sheindlin, American television personality and former judge
  9. Harry S. Truman, former President of the United States
  10. Colin Powell, American retired four-star general and former U.S. Secretary of State

Please note that these individuals are commonly identified as having ESTJ traits based on anecdotal evidence, and it's important to keep in mind that the accuracy of their personality types is subject to interpretation and debate.


Here are some estimates of the distribution of MBTI personality types in the US population:

  1. ISTJ (The Inspector): 13-16%
  2. ISFJ (The Protector): 9-14%
  3. INFJ (The Counselor): 1-3%
  4. INTJ (The Mastermind): 2-4%
  5. ISTP (The Craftsman): 4-6%
  6. ISFP (The Composer): 5-9%
  7. INFP (The Healer): 4-5%
  8. INTP (The Architect): 3-5%
  9. ESTP (The Dynamo): 4-5%
  10. ESFP (The Performer): 4-9%
  11. ENFP (The Champion): 6-8%
  12. ENTP (The Visionary): 2-5%
  13. ESTJ (The Supervisor): 8-12%
  14. ESFJ (The Provider): 9-13%
  15. ENFJ (The Teacher): 2-5%
  16. ENTJ (The Commander): 1-4%

Please note that these estimates may vary depending on the study and the sample population, and should be taken as rough estimates rather than exact figures. Additionally, it's important to remember that personality type is not a predictor of behavior or ability, and individuals of any personality type can succeed in any field or role.


To estimate the number of people who are likely to have the ESTJ personality type based on a given population size, you can use the following formula:

(number of people in population) x (estimated percentage of ESTJ) = estimated number of people with ESTJ personality type

For example, if you wanted to estimate the number of ESTJ individuals in a population of 100,000 people based on the estimated percentage of ESTJ being 8%, you could use the formula as follows:

100,000 x 0.08 = 8,000

Therefore, you would estimate that approximately 8,000 individuals in that population have the ESTJ personality type.

It's important to note that these estimates are based on the assumption that the population being analyzed is representative of the larger population and that the estimated percentage of ESTJ is accurate. Additionally, while this formula can provide a rough estimate, it is not possible to determine an individual's personality type with complete accuracy without a valid assessment tool and expert interpretation of results.


ESTJs tend to value structure, stability, and efficiency, and they are often drawn to partners who share these qualities. They also tend to be practical, results-oriented, and goal-focused, and they may appreciate partners who are similarly motivated and ambitious.

Based on these characteristics, here are some personality types that might be a good match for ESTJs:

  1. ISTJ: ISTJs share many of the same values as ESTJs, including a preference for structure and routine, a focus on practicality, and a strong work ethic. They may also appreciate the ESTJ's ability to lead and organize, as well as their attention to detail.

  2. ENTJ: ENTJs are similarly driven, strategic, and goal-focused as ESTJs, and they may appreciate the ESTJ's ability to plan and execute tasks effectively. They are also likely to value the ESTJ's straightforward communication style and problem-solving skills.

  3. ESTP: ESTPs are energetic, action-oriented, and spontaneous, which can provide a good complement to the ESTJ's more measured approach. They are also likely to appreciate the ESTJ's focus on achieving goals and may enjoy collaborating on projects or challenges.

  4. ESFJ: ESFJs are often warm, nurturing, and focused on the needs of others, which can be a good match for the ESTJ's desire for stability and harmony. They may also appreciate the ESTJ's ability to plan and organize, as well as their direct communication style.

It's important to note that while certain personality types might be a good match for ESTJs, individual differences can play a significant role in the success of any relationship. Ultimately, the key to a successful relationship is communication, understanding, and mutual respect.
