GDP per capita in the Soviet Union compared with Western Europe 1900-1950

In the first half of the 20^th century, the Soviet Union's GDP per capita rose from roughly one-third of Western Europe's GDP per capita in 1900 to one-half of its rate in 1950. Although it grew gradually between the given intervals, it did drop between 1913 and 1929 due to the devastation caused by the First World War and Russian Revolution. However, this year also marked the beginning of the Great Depression, which caused a significant economic downturn across Western Europe while being relatively unfelt in the Soviet Union.
