I there have been different interpretations of Atlantis throughout DC's years, so for the sake of clarity I'm talking about the Atlantis that's featured in the Aquaman comics.

Considering there's no information listed here https://dc.fandom.com/wiki/Atlantis - and they have every other bit of data you could hope to find - I'm going to guess it's never been officially established on page.
It's about the size of New Jersey
The J-man
oh also the city of Atlantis is only one of several Atlantean cities in DC, so there's however many other cities with their own populations.
I'm not well equipped to answer this question, but I would guess that Atlantis would have a population of at least a million people to be able to have developed such advanced technology and pose a threat militarily to the surface world.
Take this with a grain of salt.
Given the various disasters and alien invasions the DCU faces every day, I'd day Atlantis, like most other places, has a permanent population of about 6.
