The purpose of Health in Ireland, Key Trends 2011, as with previous editions, is to provide summary data on the main areas of health and health care over the past decade. It also aims to highlight selected trends and topics of growing concern and to include new data where it becomes available. A further objective is to assess ourselves and our progress in the broader EU context. With these goals in mind, the booklet is divided into six chapters ranging from population, life expectancy and health status through to health care delivery, staffing and costs.
