Migration Effects on NZ Pension Burden
I have been looking (without much success) for information that would clarify the effects of Migration on Population Age Structure, Life Expectancy and Pension Burden in NZ.
I have prepared a short discussion document, laying out the assumptions and conclusions that I have come to from first principles and what little literature there is available. The full document is HERE. If you have definitive information that confirms, refutes or adds to the discussion please post it at the full document site, and I will put it into the structure.
Essentially I conclude:-
#1 That present and future migration is statistically skewing life expectancy figures upwards
#2 That migrants will Iive longer than NZ born inhabitants
#3 They will therefore survive more years of pensionable age than NZ born superannuitants
#4 Immigrants elderly relatives, from non-reciprocal pension agreement countries, who join their families, will be part of a pension burden whose funding they have not contributed to
