I want to know the answer to the following question:
How much of Estonia speaks Russian?
All the background I'm provided with is that "For example, if 53% of ethnic Estonians between 15 and 19 claim to speak some Russian, then among the 10- to 14-year-old group, command of Russian has fallen to 19% (which is about one-third the percentage of those who claim to have command of English in the same age group).". Is that enough to answer the question?
Answer: no
