Migration: Samoa and Ukraine

Samoa -
Samoa is a net out migration based country because though they do have people coming into the country (barely), that amount does not make up for the thousands that leave annually. The largest immigrant group is Americans because Samoa is actually an unauthorized, and unincorporated territory of the US. Most Americans move there due to the fact that there's actually a military base there, so most just move for work. Most emigrants move to America because of the opportunities offered such as jobs, and not to mention family. Whereas, migration is due to the fact that Samoa is basically made of small islands of mountains and volcanoes, so citizens mostly live on the outskirts.

Ukraine - 
Ukraine is a net out migration based country because there are more people leaving than people coming. The largest immigrant group in all of Ukraine (out of Ukrainians) is Europeans. Most likely due to the fact that there's a feud going on the two at the moment about war and etc,  but it can also have to do with Russia being so close and having so many people that they just spread-ed into Ukraine. Most emigrants have moved to Russia because of the fight between Kiev and rebels in the eastern regions of Ukraine, which has killed hundreds of thousands of Ukrainians. As for the migrants, those who cannot afford to leave or don't even wish to leave their family move anywhere away from the eastern side of Ukraine because of the war between the Russian irregular forces and the Ukrainian forces in the eastern areas of Luhansk and Donetsk.

Geography: Samoa and Ukraine

Samoa:

The beautiful country of Samoa is found in the Southern part of the Pacific Ocean, which is about 2,200 mi South of Hawaii. The larger islands, Upolu and Sarai'i, are both mountainous and volcanic origins. 8 smaller islands are located about halfway between Hawaii and New Zealand in the Polynesian area. Samoa is officially the independent state of Samoa, formally known as Western Samoa (Confusing, huh?)

Ukraine:

Ukraine, the largest country in all of Europe, is very much diverse and has many interesting geographic features. For example, the mountains (Carpathian Mts) stretch ACROSS western Ukraine is bordered by the waters of the Black Sea and Sea of Azov, but major rivers include Desna, Dnieper, and etc. This just shows how much Ukraine has to show!
