In his Contrat Social J.J. Rousseau gives, as an example, the number of people
that should form 'a government'. He does that by taking the square root (racine
carrée in French)of the number of people that form the state (l'état). So,
indeed, according to this example, in a population of size n the number of high-
visibility members stands as the square root of n.
Book III, chapter 1.

> of the total production ... is in fact a rather well known formula in
> the study of elites ... Such a relationship was initially mooted by
> Jean Jacques Rousseau ..." Diodato also cites Zipf's Human Behavior
> and the Principle of Least Effort (1949): "This statement that is so
> frequently imputed to J. J. Rousseau seems to evade specific
> reference although its sense is apparent in his Contrat Social."
> Of course, the relationship between the size of a population and its
