There are only enough digits in the current set of SS#’s to accommodate 1 billion different numbers, including 000-00-0000.
The current population is in excess of 313 million. Since SS#’s are now given at birth, essentially, all the current living citizens plus all the previous ones that have died since the late 1930’s, plus all the immigrants from other nations, legal or illegal, must be approaching the mark....
Seems to me you’re talking about an approaching mark which had nothing to do with his numbers back then.
