Latvian language
Upper Latvian dialect is spoken in Eastern Latvia. It is set apart from rest of the Latvian by number of phonetic differences. The dialect has two main varieties – Selonian and Non-Selonian. There is a standard language, the Latgalian language, which is based on deep Non-Selonian varieties spoken in south of Latgale. The term "Latgalian" is sometimes also applied to all Non-Selonian varieties or even the whole dialect. However, it is unclear if it is accurate to use the term for any varieties besides the standard language. While the term may refer to varieties spoken in Latgale or by Latgalians, not all speakers identify as speaking Latgalian, for example, speakers of deep Non-Selonian varieties in Vidzeme explicitly deny speaking Latgalian.
Russians in the Baltic states
In 2011 pro-Russian groups in Latvia collected sufficient signatures to initiate the process of amending the Constitution to give Russian the status of an official language. On 18 February 2012, constitutional referendum on whether to adopt Russian as a second official language was held. According to the Central Election Commission, 74.8% voted against, 24.9% voted for and the voter turnout was 71.1%. The non-citizen community (290,660 or 14.1% of Latvia's entire population) was non entitled to vote.
