Inequalities in mortality during and after restructuring of the New Zealand economy: repeated cohort studies.

ABSTRACT:

Objectives

To determine whether disparities between income and mortality changed during a period of major structural and macroeconomic reform and to estimate the changing contribution of different diseases to these disparities.

Design

Repeated cohort studies.

Results

All cause mortality rates declined over the 2
