What percentage of Mexico speaks English?
Less than 1.6% of the Mexican population speaks English on a fluent level.
This is understandable, considering that only 2.8% of non-Hispanic homes speak Spanish in the United States.
It's hard to say, but since Lithuania was occupied by the Soviet Union, citizens had to use Russian. Therefore, almost every citizen of Lithuania who is in his thirties or older speaks Russian. The new generation however, mainly speaks in English (as well as Lithuanian of course). My estimate is 60%-80%
