Germany’s Universität Leipzig has recorded some amazing statistics of the actual current numbers 2011-2013 of secondary students studying Greek and Latin here:

That’s 3.5 million secondary students! It appears that the classics are far from dead, with small numbers of students in Congo, Egypt, Ghana, Greece, Malawi, Nigeria, Senegal, South Africa, South Korea, Spain, and Zimbabwe. In none of the countries above are Latin and Greek compulsory subjects. High school students are taking the languages to broaden their depth of knowledge.

However, repositories of translations in English such as the Loeb Classical Library must take seriously the fact that the vast majority of students of classical languages study in languages other than English. See the seminal article, “The Digital loeb Classical Library—a view from Europe” by Prof. Gregory Crane: https://docs.google.com/document/d/1JDLE-yA5sySj6zxOJQRo1vghugrf8DztAOCeaigw-IM/edit.
