I'd love to know what's the Romulan population in general or on Romulus itself in the TNG era.

  • Memory alpha says 18 billion around 2378, but no sources are given. Also, I couldn't find anything else at the moment.

According to the Star Trek: Star Charts factbook, the population of Romulus in the year 2368 is approximately 18 billion.

No information exists to describe the total number of Romulans in the galaxy, but their empire encompasses several colony worlds, each with potentially billions-strong populations of their own.

After its destruction in 2387 (about ten years after the events of Star Trek: Nemesis), the population of Romulus dropped to (approximately) zero.

  • In the Kelvin time line, Romulus was still around? It was in the original time line that Romulus was destroyed?

  • Aren't they eventually destroyed in both? Wasn't it a natural disaster that destroyed Romulus, and won't that natural disaster still happen, but now without the Vulcans to try and avert it?

  • @coteyr - A few months ago I would have argued with you that it wasn't clear however it seems the new Picard series (set in the original timeline) will also feature the destruction of Romulus

    In the Kelvin time line Romulus isn't due to be destroyed for more than a century and with that much forewarning they can doubtless save it. Mar 10, 2019 at 19:37
