Accessibility to food retailers and socio-economic deprivation in urban New Zealand

Abstract

The spatial locations of food retailers are considered to be an influential aspect of population consumption patterns. Such contextual relationships are often related to socioeconomic deprivation, with disparities in accessibility having important implications. This study used Geographic Information Systems and an Enhanced Two-Step Floating Catchment Area model of spatial accessibility to further understand such relationships within urban areas of New Zealand. Findings, while mixed, indicate that there is generally increased accessibility to all food retailers in highly deprived areas. Understanding these socio-spatial relationships in local environments has important implications for policy initiatives, health outcomes and sustainable development.
