There is no reliable worldwide count for LaVeyan Satanists in 2026, and any exact number you see online is mostly guesswork. The best-supported answer is that it remains a very small movement—likely in the low tens of thousands at most, and possibly much lower—because even broad estimates for all kinds of Satanism tend to be tiny relative to the global population.

Is it growing?

Probably only slowly, if at all in a demographic sense. What seems to have grown more is public visibility and online discussion, not clear evidence of large-scale membership growth.

Why the number is hard to pin down

LaVeyan Satanism is not a mainstream census category, so there is no global registry or consistent survey data. The tradition is also decentralized, and many people may sympathize with its philosophy without formally joining any organization.

Best practical estimate

  • Formal adherents: probably a small niche group, not a mass religion.
  • Total Satanism broadly defined: estimates vary widely, but credible sourcing does not support numbers anywhere near a meaningful percentage of the world population.
  • Trend: more cultural attention than membership explosion.

Bottom line

If you want the most honest answer: no one knows exactly , but LaVeyan Satanism is still a tiny minority worldwide, and there is no strong evidence it is rapidly growing.

TL;DR: tiny, hard to count, and not clearly surging.
