Tsarist autocracy
In the last decades of the 19th century, many Ukrainians were forced by the Tsarist autocracy to move to the Asian regions of Russia, while many of their counterpart Slavs under Austro-Hungarian rule emigrated to the New World seeking work and better economic opportunities. Today, large ethnic Ukrainian minorities reside in Russia, Canada, the United States, Brazil, Kazakhstan, Italy and Argentina. According to some sources, around 20 million people outside Ukraine identify as having Ukrainian ethnicity, however the official data of the respective countries calculated together doesn't show more than 10 million. Ukrainians have one of the largest diasporas in the world.
