In Latvia, notably, its official recognition and legality in the classroom have been a topic of considerable debate in a country where more than one-third of the population is Russian-speaking, consisting mostly of post-World War II immigrants from Russia and other parts of the former USSR (Belarus, Ukraine). Similarly, in Estonia, the Soviet-era immigrants and their Russian-speaking descendants constitute about one quarter of the country's current population.

A much smaller Russian-speaking minority in Lithuania has largely been assimilated during the decade of independence and currently represent less than 1/10 of the country's overall population. Nevertheless, around 80% of the population of the Baltic states are able to hold a conversation in Russian and almost all have at least some familiarity with the most basic spoken and written phrases. The Russian occupation of Finland in 1809–1918, however, has left few Russian speakers to Finland. There are 33,400 Russian speakers in Finland, amounting to 0.6% of the population. 5000 (0.1%) of them are late 19th century and 20th century immigrants, and the rest are recent immigrants, who have arrived in the 90's and later.
