There's often times a hidden variable in the decision to return home - in my case it involved nice curves and brown eyes. I'm a Kiwi and many of us head off overseas in our early twenties, usually with the intention of returning home in a few years. This 'Big OE' though is mostly because people want to see the world rather than because they want to move somewhere to improve their quality of life. So that's part of the explanation for the difference the study sees between migration between Western migrants and those from Asian regions say. On their travels some people meet a pretty girl / handsome guy and so sometimes the new partner returns to New Zealand too and sometimes the Kiwi ends up staying in the new partners country. The decision in these cases is more a personal one than to do with any specific countries advantages / disadvantages.
