* Country: Completion rates differ drastically between countries due to varying educational systems, access to resources, and cultural norms.
* Type of institution: Students attending four-year colleges and universities have different completion rates than those attending two-year colleges or vocational schools.
* Student demographics: Factors like socioeconomic status, race, and age influence degree attainment rates.
There's no single, universally applicable percentage. While some studies may provide national averages for specific countries, those numbers will not reflect the global picture or account for the nuances mentioned above. To find a relevant statistic, you'd need to specify the country, type of institution, and potentially demographic information you're interested in.
