The overall aim of this study was to establish a microsimulation model of the primary healthcare system in New Zealand in its social context, and to test propositions about its functioning and development under different scenarios of demographic ageing. Central were three elements: demographic ageing and associated morbidity, family and community capacity to cope, and practitioner and system response. Data from existing sources were combined and used to estimate the key parameters for deployment in the microsimulation model. Advanced methodological techniques were applied in statistical matching, modelling, and simulation.
