Building Back Better: Do Post-Earthquake Neighborhoods Promote Active Aging? A Long-Term Audit Analysis in Christchurch, New Zealand

Abstract The design of urban environments often influences neighborhood physical activity and is crucial to supporting the health and mobility of aging urban populations. However, changes to urban infrastructure take time to implement and are rarely evaluated over long periods. In this study, we examined the long-term outcomes of rapid urban change and rebuilding following a sequence of devastating earthquakes in Christchurch, New Zealand. The study drew on a novel mixed-methods approach, including on-site environmental audits, desktop spatial analyses, and subjective auditor observations, to track support for active aging over a decade of post-disaster rebuilding in 10 aging neighborhoods.
