What percent of the world has the phobia geliophobia?

Geliophobia, the fear of laughter, is considered a rare phobia, and specific prevalence statistics are not well-documented. Estimates suggest that phobias, in general, affect about 7-12% of the global population, but geliophobia is not commonly included in these studies. Therefore, it is difficult to determine an exact percentage of the world affected by geliophobia, but it is likely to be a small fraction of the population.
