Hi!  As far as I know there really isn't a digit in our number system
which is used more then any other.  All of the digits which we use to
make numbers get a lot of use -- in fact I'll bet you use all of them
many times a day.

Subject: asymmetric distribution of digits in real life

Hello there,

A couple of years ago I saw some kind of study about exactly
this subject. It stated that if you extract and compare a large
number of digits from real life sources (birth dates, company
balances, temperatures...), there actually exists an asymmetric
distribution. The digit "1" is supposed to be more frequent than
the "2", which in turn is more frequent than the "3" and so on.

Furthermore, this study described a procedure to use this phenomenon
to distinguish between arbitrarily set values (such as a fake income
declaration) and values that evolved in real life.

who has had anything to do with a similar subject who might help me
find this study?

Hi Carsten,

You're undoubtedly referring to "Benford's Law", which is sometimes
known as the "leading digit phenomenon", and notes that the most
different question than "What is the most commonly used digit?",
although the two are closely related.  A starting point is the
following web page in our archives:

Hi,

Thanks a lot, this was exactly what I have been looking for!

Ciao,
