Lithuania, officially the Republic of Lithuania, is located in Northern Europe along the Baltic Sea east of Denmark and Sweden.
Interestingly, native inhabitants of Lithuania have never been replaced or pushed out by any other ethnic group since the Neolithic period. This means modern-day Lithuanians have much of the same genetic composition of their ancestors. Lithuania has a fairly homogeneous population with no apparent genetic differences between subgroups of ethnicities. A DNA analysis conducted in 2004 found that Lithuanians are closest to Finns, Estonians and Latvians.
Ethnic Lithuanians account for 5/6 of the population, which makes the country one of the most homogeneous in the Baltic States. The 2011 census found that 84% of the population was ethnic Lithuanians who spoke Lithuanian. Poles made up 6.6%, followed by Russians (5.8%), Belarusians (1.2%) and Ukrainians (0.5%).
Poles are mostly concentrated in southeast Lithuania, while Russians are mostly in Vilnius and Klaipeda. There are approximately 3,000 Roma in Lithuania, as well as a small community of Tatar.
The main religion in Lithuania is Roman Catholic.
Lithuanian is the official language in use in the country, and the population also uses Russian and Polish as well as other unspecified languages.
The age structure in Lithuania is around 26% under the age of 25, 54% between the ages of 25 and 64, and nearly 20% are over the age of 65. The current median age as of 2018 is calculated at 43.7 years of age.
In terms of quality of life and access to necessary resources, Lithuania is doing fairly well. Less than 12% of the population struggle with access to clean water and improved sanitation facilities. In addition, the World Happiness Report shows a ranking of 50th in 2018, with an overall happiness rating that comes to 5.952 out of 10 possible points.
