Per-country rates of Esperanto speakers
I fitted a model to this data and used it to estimate the relative frequency of Esperanto speakers in each country. Using population census data from Lithuania, Estonia, Russia, New Zealand (but not Hungary), I have scaled all relative frequencies to get the total number of Esperanto Speakers in each country. The total number of Esperanto speakers is estimated to 62983.9.
