Latgalian language
Latgalian is spoken in Latgale, the eastern part of Latvia. It is debated whether it is a separate language or a distinct dialect of Latvian. Nevertheless, its standardized form is recognized and protected as a "historical variety of the Latvian language" "(vēsturisks latviešu valodas paveids)" by Latvian law. The 2011 Latvian census established that 8.8% of Latvia's inhabitants, or 164,500 people, speak Latgalian daily. 97,600 of them live in Latgale, 29,400 in Riga and 14,400 in the Riga region.
Latvian language
During the Soviet occupation (1940–1991), the policy of Russification greatly affected the Latvian language. Throughout this period, many Latvians and Latvia’s other ethnicities faced deportation and persecution. A massive immigration from the Soviet republics of Russia, Ukraine, Belarus and others followed, largely as a result of Stalin's plan to integrate Latvia and the other Baltic republics into the Soviet Union by means of Russian colonization. As a result, the proportion of the ethnic Latvian population within the total population was reduced from 80% in 1935 to 52% in 1989. In Soviet Latvia, most of the immigrants who settled in the country did not learn Latvian. Today, Latvian is the mother tongue of more than 60% of the country's population.
