Push & Pull Factors

What are push and pull factors?  Push factors are negative things about a place that makes you want to leave. Now that you know that, pull factors are exactly the opposite.  My elders have migrated from Tuvalu to New Zealand for a better living.  Furthering their education was another, also seeking for job opportunities. Tuvalu had fewer opportunities, that's what made my elders decided to move to New Zealand. They've found New Zealand a clean and stable environment. Their overall experience was an amazing one. They had met their long lost families and friends whilst in New Zealand.
