I think this reveals the generational polarity between NFPs and STJs more than anything.
Great data on the thread, would you had more data to share, even in PM? Im always interested.

This is not the only source of data that states this... I read by more than a year into another study, independent from official MBTI, that reached to the conclusion that there is a dichotomy migration from ENFP to ISTJ in american society (it didnt accessed the types directly, only the dimensions), which pretty much agrees with what you post, however it is unknown and inconclusive if the new generation is turning more ENFP and less ISTJ OR if MBTI type really changes from time to time and people get more ISTJ and less ENFP as they age. We would need to find a more older study, something like a similar study of that made in the 90s or 80s to make a deduction out of that information. I already searched through google scholar and regular google and I failed to find a study like that. This kind of info is really rare because it could be a MBTI achile heels, because if people really change type through age that really compromises a lot of MBTI (the kind of stuff that usually "glitches" the whole system are quite rare to find it).
 
After some few time of "investigation" and exploration, I did came to a reasonable explanation to both "Why is INFJ the rarest type?" (https://www.infjs.com/threads/why-is-infj-the-rarest-type.38214/page-9) and the explanations behind the image below the MBTI types through different age coming from this thread Official MBTI Statistics.

But this requires that one of these 3 links below works (because searching had been difficult last month - disappeared from Google Scholar simple search) and these links are going to lead to a read of a few pages from a book...

There is a theory called ego-control and ego-resiliency from Block & Block. This theory validation is a little bit hard to access from the internet - except in one of its most common use, as a typology for the Big Five. Yes, its a typology based on clustering - basically, types by data science, where people analyze hundreds or thousands or up to hundreds of thousands of tests results on Big Five, recognize clusters, and through these clusters types are formed. This personality typology is the most scientific ever because it is falsifiable and can be subject of replication - and it has been through the years. So just a few articles that I've searched randomly, just to exemplify:

https://www.sciencedirect.com/science/article/abs/pii/S027273581630294X

https://journals.sagepub.com/doi/abs/10.1002/per.557

https://onlinelibrary.wiley.com/doi/abs/10.1002/per.495

https://onlinelibrary.wiley.com/doi/abs/10.1002/per.495

(these are not the links that are supposed to work yet...)

These typologies are a part of an empirical finding (it has a few controversies...such as that types are similar but different in different contexts and countries AND the failure of a good replication on HEXACO) and originally it was meant to bring support to theory.

The core part of the theory is presented on "Development of Cognition, Affect, and Social Relations
The Minnesota Symposia on Child Psychology, Volume 13", on chapter 2 with the name “the role of ego-control and ego-resiliency in the organization of behavior”.

Hopefully, one of these 3 links will work:

https://books.google.com.br/books?id=6fghAwAAQBAJ&printsec=frontcover&hl=pt-BR#v=onepage&q&f=false

https://books.google.com.br/books?i...avior&lr&hl=pt-BR&pg=PA43#v=onepage&q&f=false

You should be directed to a book written “2 - The role of ego-control and ego-resiliency in the organization of behavior” starting with “For what now approaches 30 years”. Read from that first phrase, which is page 39, until page 51 right before “the longitudinal study”.

I hope they did work (or you guys found a good way) otherwise writing this was sort of a waste of time (so yeah, Im betting it did work).

So proceeding to the explanation, Introversion is related to high ego-control even though is not the same as it is explained on the book, but keep in mind that it correlates - so higher inhibition relates to both introversion and high ego-control and 'boastful' talking relates to lower ego control and extraversion. At the same pace, the J style of the MBTI J - organized, scheduled, planned, disciplined, relates to high ego-control either. So IXXJ relates to high ego-control while EXXP relates to low ego-control.

Now comes part 2 - where intuition kicks in. As it is mentioned on the book, there is the integrated concept of permeability on ego-control - "overcontrol: Excessive boundary impermeability (...) undercontrol: Excessive boundary impermeability". The systems they are referring to are actually systems and inside these different systems there are the conscious and the many parts of the unconscious (in case you don't know, the unconscious is not a single entity neither in neuroscience, nor in Freud nor in Jung). An intuitive by Jung's and MBTI's definition is more in touch with the unconscious than when compared to a sensor, so N does relates to a higher permeability and lower ego-control.

So IXXJ means that a person is inhibited (I) and more disciplined (P), IXXJ automatically has a tendency towards high ego-control, which in turn means less permeability and thus less likehood of being in touch with the unconscious, so given a person is IXXJ, the person is less likely to be in touch with the unconscious due to this mechanism, meaning that the person will be less likely to be a N and more likely to be a S, that is why ISTJ+ISFJ>>INFJ+INTJ and that is why INFJs and INTJs are so much rare. Even if we rip off the MBTI J/P, that still holds true to Jung's Ni originally. On the other hand, EXXP means that a person is less inhibited (E) and less disciplined (P), thus more permeability and more likely to be touch with the unconscious, and that is why ENTP+ENFP almost equals ESFP + ESTP in numbers regardless the 2 Sensors : 1 Intuitive proportion (its more like 7 sensors per 3 intuitives, actually). Since Feeling relates at least a bit but not totally to emotions, and a flow of emotions does relate to higher ego-control (its written on the book that an undercontroller is supposed to be mroe emotive), thus EXFP will have a strong tendency towards low ego-control even higher than EXTP, which will push intuition up, and that is the best explanation why ENFP is the only intuitive type more common than its sensor's counterpart, ESFP. This is also why there is the ENFP-ISTJ polarization on MBTI stats (if you evaluate internal correlations, it forms ISTJ-ENFP and no other opposing pair; ENFP is the most common intuitive while ISTJ is the most common sensor).

There is one more part: Ego control and aging. There is one part of the brain that relates to ego-control: Prefrontal cortex.
"The researchers from the European Molecular Biology Laboratory discovered “prominent connections” between two parts of the brain: the prefrontal cortex and the brainstem, which is at the base of the organ and leads to the spinal cord. According to a statement from the lab, experts already knew that the brainstem was involved in instinctual behavior and suspected that the prefrontal cortex played a role in how we control it, but did not understand how the latter region did that."(https://www.medicaldaily.com/self-control-and-human-brain-neuroscience-impulse-control-408348)

"This brain region has been implicated in executive functions, such as planning, decision making, short-term memory, personality expression, moderating social behavior and controlling certain aspects of speech and language.[4][5] Executive function relates to abilities to differentiate among conflicting thoughts, determine good and bad, better and best, same and different, future consequences of current activities, working toward a defined goal, prediction of outcomes, expectation based on actions, and social "control" (the ability to suppress urges that, if not suppressed, could lead to socially unacceptable outcomes).

The frontal cortex supports concrete rule learning." (https://en.wikipedia.org/wiki/Prefrontal_cortex)

"Although brain development is subject to significant individual variation, most experts suggest that the brain is fully developed by age 25. For some people, brain development may be complete prior to age 25, while for others it may end after age 25. The mid-20s or “25” is just an average age given as checkpoint for when the brain has likely become mature.

It may seem logical that those aged 18 to 25 are completely mature, the brain still is maturing – specifically the area known as the “prefrontal cortex.” (https://mentalhealthdaily.com/2015/02/18/at-what-age-is-the-brain-fully-developed/)

Adolescents and people at their earlier 20's does NOT have a full developed prefrontal cortex and their ego-control is lower than people of higher age, thus they tend to be lower on ego-control, and that impacts on the MBTI, increasing the numbers of ENFP (the lowest extreme ego-control inside MBTI specifically) at earlier years and decreasing the numbers of ISTJs. As they age, ego-control increases, and that creates the overall movement you see from ENFP to ISTJ on the graph at earlier age. This does justify most of the movement but not entirely, since ENTP doesn't move much on the graph. Also, the changes at the elderly ages are probably another story, even though by Conscientiousness Ps tends to die earlier than Js (more reckless and more likely to be involved in accidents; Less caring about your own health) which explains part but not total the movement of the final graph. Also notice that MBTI can be a little bit vague and things gets more clear if you put up the enneagram; Not all ENFPs and ENTPs are necessarily low on ego-control (but most are), for example ENTP 5 have a more neutral tendency on ego-control. But a properly typed ENFP 7 and ENTP 7 are low on ego-control by conceptual definitions of both ego-control, ENFP/ENTP and E7.

But grasping this requires an open mind, since this contradicts the "you are MBTI XXXX since you are born" and "MBTI/Jung type doesn't change" dogma... and maybe some other few dogmas as well.
