GDP per capita 1870-1913, by region

In 1820, Western Europe was the region with the highest GDP per capita, however the non-European developed countries of the United States, Canada, Australia, and New Zealand saw their average GDP per capita grow much higher by the outbreak of the First World War. These developed nations and Europe were the only regions where GDP per capita was higher than the global average, while all other regions were below (although Latin America did have an above average GDP in 1820).
