What percentage of public schools wear uniforms in the world?

There's no readily available, globally comprehensive data on the percentage of public schools that require uniforms worldwide. Such data would be incredibly difficult to collect due to:

* Vast differences in educational systems: The structure and administration of public education vary enormously from country to country.

* Lack of centralized data collection: There's no single international organization tracking this specific statistic for all nations.

* Variations in "uniform" definitions: What constitutes a "uniform" can be subjective. Some schools might have a dress code, while others have strictly enforced uniforms.

While you might find statistics for individual countries or regions, a global percentage is currently unavailable.
