Oleg,
Thanks for clarifying the term.
I defer to others' understanding of the database in question as to
whether this is a good estimator.

Ok, then I'll continue with mine line of thinking.
From the RIR stats files that RIRs publish daily we could get the
numbers of distinct resource holders. They are:
AFRINIC 1310
APNIC 7957
ARIN 35380
LACNIC 4278
What is the definition of a "distinct resource holder?" Does this
correspond to an account with the RIR, or is there some other definition?
I count the number of distinct reg-ids in the RIR statistics files
(ftp.<RIR>.net/pub/stats/<RIR>/delegated-<RIR>-extended-latest, where
<RIR> is in {afrinic,apnic,arin,lacnic}). The file format document
defines this field as:
This is an in-series identifier which uniquely identifies a single
organisation, an Internet number resource holder. All records in
the file with the same reg-id are registered to the same resource
holder.
