Azerbaijan though not a popular destination for immigrants, has recently experienced waves of immigration with the collapse of the Soviet Union, especially from ethnic Azerbaijanis mostly from Armenia (as refugees), Russia and the rest of the former Soviet Union. Meskhetian Turks were also relocated to Azerbaijan from Central Asia before and after the end of the Soviet Union. With the booming petroleum industry, immigration from Turkey has also followed. In 2010, every eighth resident in Azerbaijan was a migrant, of whom more than 90% of them are Azerbaijanis and 70% are internally displaced persons from the territories occupied by Armenia.
