Germany’s Universität Leipzig has recorded some amazing statistics of the actual current numbers 2011-2013 of secondary students studying Greek and Latin here:
“Total number of secondary level students studying Latin and Ancient Greek in the world” by Emily Franzini, Humboldt Chair of Digital Humanities, and postdoctoral candidates Thomas Koentges and Maryam Foradi:
USA: 120,000 Latin, 2,210 Greek
United Kingdom: 15,000 Latin, 2,000 Greek
France: 501,100 Latin, 34,000 greek
Denmark: 500 Latin, 100 Greek
Flanders: 40,460 Latin – 9%, 5,760 Greek
Germany: 800,000 Latin, 7,000 Greek
Switzerland: 12,970 Latin – 16.8% of all students, 930 Greek
Italy: 2,000,000 Latin – 40%(!), 680,000 Greek
Croatia: 24,737 Latin, 2,878 Greek
Bulgaria: 500 Latin, 400 Greek
New Zealand: 1,501 Latin, 0 Greek
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.
Prof. Gregory Crane of Leipzig and Tufts University, Director of the Perseus Project, gives a good overview in his presentation, “June 1914 and Classical Philology for the 21st century” here: http://biblindex.hypotheses.org/files/2014/05/2014-06-03-lyon-gcrane-light.pdf.
