       | 
       | One of my parents comes from a poor rural area of Europe where
       | well into the 60s, it was normal to have a "real" birthdate & an
       | "official" birthdate. This was because the government only issued
       | birth certificates in the nearby city, and being poor & rural, it
       | took time to get there by bus, etc.
       | 
       | So I have aunts & uncles with real-official birthdate deltas of
       | up to 2 weeks.
       | 
       | I'd imagine that going back to 1900s or 1880s, when travel was
       | more difficult, who knows. Further, it is possible that the
       | office in some of these areas for registering births was only
       | open certain days of month/week, the further back you go, etc.
       | 
       | Maybe they only went into the city on market days when they had
       | other business, on the first Monday of the following month.
       | 
       | Don't discount superstition and people registering births on
       | nearest special days like saints days, etc.
       | 
       | Some of these abnormalities get lost to time. Many of my family
       | didn't realize they had a real-official birthdate gap until 30+
       | years later when their mother told them.

       | anyone alive to confirm some facts. My paternal grandmother's
       | birth certificate was gone before the end of WW2 and when asked
       | she would give an age six years younger - initially it was to
       | prevent a scandal because not only was my grandfather of lower
       | status (Pah! "Just" a doctor! Scandalous, I daresay!), he was
       | younger.
       | 
       | As for my maternal grandparents their age is confirmed by their
       | marriage certificate(would be harder to obtain one with this date
       | as a younger person), children in their late 60s and living
       | siblings of my grandpa, of whom there are seven.

           | So first Yvonne's husband Joseph requested leave from the
           | military and was granted it because his wife was sick, we
           | have the record of that from the military. There is a picture
           | of Yvonne at a sanitarium for TB patients around this time
           | period, further establishing she had TB and was ill. Then the
           | priest administered last rights and Yvonne died. There was a
           | funeral mass that many people attended and a viewing of the
           | body at the family home. This is in newspapers from the time.
           | There are no accounts of Jeanne being ill in this time
           | period.
           | 
           | So for this switch to have happened we would have had to have
           | the daughter sick, then the mother secretly gets sick just in
           | time for the daughter to recover. The mother dies and they
           | come up with this plan to dodge taxes, even though presumably
           | it would be risky and Joseph could lose his position as an
           | officer in the army if they are caught. They get the town's
           | doctor, priest, and newspapers to go along with the fraud.
           | All of this to avoid a tax of about 6% of Jeanne's wealth, a
           | considerable sum but do you really think it would be worth
           | all the risk? At the end of the day, because of her status as

         | The odds of such an age difference are extremely small

         | has proven to be pretty accurate for the majority of the

         | biological entities like humans, one only need a single
         | exceptional mutation or pathology to be a super-human of some
         | sort, not fitting into the model at all. In fact, the tallest
         | man in history is also a statistically impossible outlier, yet
         | there 's no doubt about his existence and actual height, he
         | just happened to have a rare condition that caused him to grow
         | up to a disproportionate height. (And if you grabbed a Guinness
         | book of records, you'll find these kinds of things in almost
         | every category related to human anatomy or physiology).
         | 
         | Confusing the models with reality is a very common mistake in
         | the history of science, often committed by people having a math
         | background instead of a physics one, but not only. A very
         | famous example is how French explorer Dumont d'Urville was
         | ridiculed when he described the rogue waves he witnessed in the
         | Indian Ocean, because such a wave would be statically
         | impossible. It turned out that the physical model of waves at

         | exist (and AFAIK we're still looking for a proper model

       | 
       | For example, both my grandpa and grandma had two birthdays each,
       | in two different calendar systems, that pointed to wildly
       | different points in time. Nobody remembered exactly when they
       | were born. My other grandma was recorded as being four years
       | older than she thought she actually was, and nobody knows the

       | _several years late_ , though the document itself pointed to the

           | I think you're thinking of Benford's law:
           | https://en.wikipedia.org/wiki/Benford%27s_law
           | 
           | It's pretty strange, basically if you have a document with a
           | bunch of numbers (say, some company's quarterly report), look
           | at the leading digit of all the numbers. For some reason,
           | numbers with a leading digit of 1 show up more often than
           | those with a leading digit of 9 (i.e. 1,234,567 is more
           | likely that 987,123).
           | 
           | You'd think there wouldn't be any particular pattern in the
           | leading digit, I mean why should there be? But observational
           | data seem to suggest a pattern.
           | 
           | So Benford's law can be used as a leading indicator of fraud.
           | If you apply it to a quarterly report and there's an
           | unusually high distribution of 8's, for example, then while
           | you can't be certain that it's fraud, it might be flag to an
           | inspector/regulator to take a closer look.

             | When that's the regime, the number spends 1/3rd of it's
