Migration, push and pull factors

Push and pull factors are when someone wants to leave the country because their is a reason why they are leaving. The reason could be economic, political, cultural and environmentally. My Nana had left Raro Tonga when she was 16 because she needed to get more money for her family back at Raro Tonga. She also find out while in Raro Tonga their was a job awaiting for her. When she arrived in New Zealand she had the job but she didn't really know how to speak English, so she went school in New Zealand and in a year she was really good at speaking English.
