Gli studi recenti sulla mortalità per causa in Italia hanno messo in luce, in modo sintetico ed efficace, le differenze di mortalità tra province. Tali studi, basati su metodi di analisi multivariata di tipo classificatorio, hanno individuato aree territoriali omogenee dai confini nettamente definiti, assumendo implicitamente che non vi siano analogie comuni nei modelli di mortalità di zone confinanti. In realtà sembra naturale pensare che popolazioni vicine siano esposte a rischi di morte derivanti da comportamenti individuali comuni o da caratteristiche proprie del contesto ambientale in cui le popolazioni vivono.

Abstract
Recent Italian research on death by cause has pinpointed mortality differences between provinces. These studies, based on classification type multivariate analyses, identified homogeneous geographical areas with clearly defined borders, implicitly assuming no shared analogies in mortality models in bordering areas. In reality, it is natural to assume that neighbouring areas are exposed to mortality risks deriving from similar individual behaviour or from features of the surrounding environment.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
