Zhovti Vody
From west to east, the region includes the cities of Kryvyi Rih, Zhovti Vody as well as parts of the more "rural" parts of Kamianske and Kryvyi Rih Raions and (factually) includes far more territories in central and southern parts of Ukraine. The Kryvyi Rih area doesn't have an administrative center; each city in the area has its own administration.
