Nobody has to register anywhere to program in perl, so absolute numbers are hard to find.

I just looked into my cpan local cpan mirrors: 

cpan-mirror/authors/id$ find . -mindepth 3  -type d |wc -l
4129

So we have a bit more than 4000 CPAN authors. How many perl programmers actually publish stuff on CPAN? perhaps 1%? So my rough guess is 5e5, or half a million.

Other sources you could use, if you had access to them (you might actually some of the numbers somewhere on the internet): perl.org and cpan.org access statistics, perl book sales, perlmonks.org registered users, *comp.lang.perl.* posting statistics, rt.{perl,cpan}.org statistics (number of distinct email addresses), ...

All those have in common that you still get no really good numbers, but you might get a feeling for the order of magnitude.
