Are anagamis/arahants common (1000+) nowadays? The question is likely inappropriate here, but I'll try anyway. Hopefully nobody will take offense.
Are anagamis/arahants common (1000+) nowadays?
&quot;Uncommon&quot; would be, for example, that all the anagamis/arahants you know are renowned teachers. Likely less than 100 worldwide.
On the other hand, &quot;common&quot; would be if you know of 3 or 4 anagamis/arahants around in the same temple. Hinting at a much bigger number worldwide, on the thousands.
I'm sure someone that goes frequently to temples can give a clear answer. Or maybe someone can do some back of the envelope math.
Thanks.
In Udana 7.2, Ven. Sariputta (the Arahant) tried to teach Ven. Bhaddiya without realizing that he too was an Arahant.
The Buddha saw this and exclaimed the verse, describing Ven. Bhaddiya:

He has cut the cycle, has gone away to freedom from longing. The
dried-up stream no longer flows. The cycle, cut, no longer turns.
This, just this, is the end of stress.

This shows that the Buddha could recognize who is an Arahant, but not another Arahant (who does not possess psychic powers).
In addition, in the Bhikkhu Patimokkha, there is a rule forbidding monks from confessing their factual attainments to lay people:

Should any bhikkhu report (his own) superior human state to an
unordained person, when it is factual, it is to be confessed. -
Pācittiya 8

Hence, it is impossible to identify arahants or draw up statistics.
