Latvian language
The history of the Latvian language (cf. below) has placed it in a peculiar position for a language of its size whereby it is spoken by a large number of non-native speakers as compared to native speakers. The immigrant and minority population in Latvia is 700,000 people: Russians, Belarusians, Ukrainians, Poles, and others. The majority of immigrants came to Latvia between 1940–1991; supplementing pre-existing ethnic minority communities (Latvian Germans, Latvian Jews). In a recent survey, 60% of Latvia's ethnic minorities described their knowledge of Latvian as fluent. Fluency in Latvian is prevalent among the younger generations of the minorities.
Demographic history of the Vilnius region
The city of Vilnius, now the capital of Lithuania, and its surrounding region have at various times come under Polish-Lithuanian, Russian, Polish, German, and Soviet rule. The population has been categorised by linguistic and sometimes also religious indicators. At the end of the 19th century the main languages spoken were Polish, Lithuanian, Belarusian and Russian. Both Catholic and Orthodox Christianity were represented, while a large proportion of those within the city were Jews. The "Lithuanian" element was seen as declining, while the "Slavic" element was increasing.
