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.
Lithuania
Ethnic Lithuanians make up about five-sixths of the country's population and Lithuania has the most homogeneous population in the Baltic States. In 2015, the population of Lithuania stands at 2,921,262, 84.2% of whom are ethnic Lithuanians who speak Lithuanian, which is the official language of the country. Several sizeable minorities exist, such as Poles (6.6%), Russians (5.8%), Belarusians (1.2%) and Ukrainians (0.5%).
