Unstable political situations at home and prosperous economies abroadWhat are the main reasons why people decide to immigrate to other nations?It would depend entirely on where they're emigrating from. Somebody living on the Tuvalu islands would pick d as a reason to leave. Somebody living in Pakistan would pick c. Somebody living in Africa and going to Europe or Asia would probably pick b. As for a, I'm not so sure, is there anywhere with pop culture and a wealth of natural resources? America maybe, but nobody's immigrating to America for the Pennsylvania coal mines.What are the main reasons why people decide to immigrate to other nations?Mainly b and c, but DEFINITELY not d.
