Work and Timing of First Live Births in New Zealand

Abstract

In this paper we have used data from a nationally representative sample survey of New Zealand women (N=2673) aged between 20 and 59 years. We employ life-table technique and proportional hazard modelling to assess the role of individual and group level variables in determining the timing of first live births. This study suggests that a woman's decision to work and to have children and when to have them are intimately linked. While the age at which women obtain their first job has not changed much over the generations the age of the mother when her first child was born has risen considerably over recent generations. The result has been a widening period of time between the first job and the first child (for both Maori and non-Maori). Our analysis suggests that the number of years a woman has worked is very closely associated with when she has her first child having worked increases the chances of having a child, but as the work experience lengthens so this chance declines.
