how many aliens

Answered by GPT-5 mini AI
Do you mean extraterrestrial life (space aliens), people called “aliens” (non‑citizen/immigrant residents), or something else?

Quick answers by interpretation:
- Extraterrestrial life: Unknown — no confirmed aliens. There are billions of potentially habitable planets in the Milky Way and trillions across the observable universe, so scientists consider life possible elsewhere, but we have no confirmed count.
- Non‑citizen people (e.g., “aliens” in immigration statistics): worldwide there were about 280–280+ million international migrants around 2020 (UN estimate). In the United States there are roughly 45–48 million foreign‑born people in the early 2020s (about 13–15% of the population).
- If you meant something else (UFO sightings, fictional aliens, a specific country’s stats), tell me which and I’ll give numbers and sources.
