I want to know the answer to the following question:
What percent of the population has completed non-mandatory upper secondary education?
All the background I'm provided with is that "Of the 24,311 who completed tertiary schooling, 51.6% were Swiss men, 33.0% were Swiss women, 8.9% were non-Swiss men and 6.5% were non-Swiss women.". Is that enough to answer the question?
Answer: no
