To find a specific number or percentage, you'd need to specify the country, year, and potentially other demographics you're interested in, and then consult relevant educational statistics from that country's government or educational organizations. Organizations like the National Center for Education Statistics (NCES) in the U.S. or equivalent bodies in other countries collect and publish this data.
