Migration model

This migration model shows the movement between tokelau and new zealand. Mainstream Flow is much bigger than the counterstream flow because there are more tokelauan people migrating to new zealand. But there's not much tokelauans returning back home. Their are push and pull reasons why they migrate to another country. The push reasons are the negative reason why people leave their place of origin. (Eg) The push reason the sea levels might rise up and cover their homes. Pull are the positive reason that attract people to a new place. (Eg) And the pull reason could be to get better learning and experience of the country.
