Estonians have strong ties to the Nordic countries and Germany stemming from the strong cultural and religious influences gained over centuries during Danish, German and Swedish rule and settlement. This highly literate society places strong emphasis upon education, which is free and compulsory until age 16. The first known book in Estonian was printed in 1525.
Written with the Latin alphabet, Estonian is the language of the Estonian people and the official language of the country. One-third of the standard vocabulary is derived from adding suffixes to root words. The oldest known examples of written Estonian originate in 13th century chronicles. During the Soviet era, the Russian language was imposed in parallel to, and often instead of, Estonian in official use.
Between 1945 and 1989 the share of ethnic Estonians in the population resident within currently defined boundaries of Estonia dropped from 96% to 61%, caused primarily by the Soviet program promoting mass immigration of urban industrial workers from Russia, Ukraine, and Belarus, as well as by wartime emigration and Stalin's mass deportations and executions. In the decade following the reconstitution of independence, large scale emigration by ethnic Russians and the removal of the Russian military bases in 1994 caused the proportion of ethnic Estonians in Estonia to increase from 61% to 69% in 2006.
Modern Estonia is a fairly ethnically heterogeneous country, but this heterogeneity is not a feature of much of the country as the non-Estonian is concentrated in two of Estonia's counties. 13 of Estonia's 15 counties are over 80 percent ethnic Estonian, the most homogeneous being Hiiumaa, where Estonians account for 98.4% of the population. In the counties of Harju (including the capital city, Tallinn) and Ida-Viru, however, ethnic Estonians make up 60% and 20% of the population, respectively. Russians make up 25.6% of the total population, but account for 36% of the population in Harju county, and 70% of the population in Ida-Viru county.
