Reliable figures from current research — from global population to regional data, from the spectrum to genetics.
For decades, aphantasia was treated as a curious one-off — today we know that 3 to 5 % of people have it. Worldwide, that's roughly 240–400 million. This page summarizes the reliable figures from current research.

Aphantasia is a spectrum — from complete absence of imagery to extremely vivid mental images.

The most current estimates come from studies by Zeman et al. (2020), Dance et al. (2022), and the Aphantasia Network survey with over 14,000 respondents. All use the VVIQ as the measurement instrument, with different cut-offs:
The 3–5 % range isn't uncertainty — it's a question of definition threshold. For practical purposes, 4 % is a reasonable middle value.

Existing research shows men have aphantasia slightly more often than women (about 4.2 % vs. 3.5 %). The difference is statistically significant but small and shouldn't be read as "typically male". The majority of affected people of every gender lead full lives with aphantasia.
5 to 6 times higher likelihood in close relatives
— Dance et al. (2022)
Studies by Dance et al. show: someone with aphantasia is about five to six times more likely to have a close relative with aphantasia. That points to a genetic component. Which genes are involved is not yet conclusively known as of 2026 — candidates include genes related to connectivity between visual cortex and frontal lobe.
Aphantasia is not a yes/no state but a spectrum. The VVIQ scale ranges from 16 (complete absence of imagery) to 80 (extremely vivid images). About 4 % are at the low end, about 3 % at the high end, the rest distributed in between. Someone with a VVIQ of 24–35 ("markedly below average") doesn't have "mild aphantasia" — they simply have less vivid mental images than average.
Different numbers in different studies don't come from researcher uncertainty. They come from different VVIQ cutoff values including different populations.
With a strict cutoff (VVIQ ≤ 23) it's 2.6 %. With a broader one (VVIQ ≤ 40) it's 5 %. For everyday purposes, 4 % is a reliable middle value.
Likely yes. Aphantasia is congenital in most cases, so prevalence stays constant over life. It has been hard to study in children because the VVIQ requires verbal reflection from age 12+.
Current studies show no relevant regional differences. Prevalence in the US, UK, Germany, Australia, and Japan is comparable. This supports a biological rather than cultural basis.
Self-report estimates suggest over half of affected people discover aphantasia only after age 25. Many lived decades assuming "imagine that" was metaphorical for everyone.
Aphantasia appears disproportionately in technical-mathematical professions and software development. Whether that's causal (less visual distraction when coding) or selection (jobs that work without mental images) is an open question.
Take the scientifically validated VVIQ test in 5 minutes and find out if you are among the 3–5 %.
