Sex ratios and ‘missing women’ among Asian minority and migrant populations in Aotearoa/New Zealand: a retrospective cohort analysis

Recent research from the UK, USA, Australia and Canada point to male-favouring sex ratios at birth (SRB) among their Asian minority populations, attributed to son preference and sex-selective abortion within these cultural groups. The present study conducts a similar investigation of SRBs among New Zealand’s Asian minority and migrant populations, who comprise 15% of the population.
