Podsumowanie	The Active Ageing Index (AAI) is a composite indicator that measures the untapped potential of older people to contribute to the economy and society and to live independently. Developed jointly by the United Nations Economic Commission for Europe (UNECE) and the European Commission and documented by Asghar Zaidi and colleagues in 2013, it summarizes how far older men and women realize their potential for active and healthy ageing. The index is organized into four domains: employment; participation in society; independent, healthy, and secure living; and capacity and the enabling environment for active ageing. Across these domains it aggregates 22 individual indicators drawn largely from existing comparative surveys. Each indicator is normalized to a common scale, combined within its domain, and then weighted across domains into a single overall score that allows countries to be compared and ranked. The AAI was created to support evidence-based ageing policy in the European Union and beyond, providing a benchmarking tool for member states. It treats active ageing not as a property of exceptional individuals but as something policy and the environment can enable across the whole older population.	Healthy life expectancy partitions ordinary life expectancy into the years a person can expect to live in good health and the years expected to be lived with disability or ill health. Building on the life table, the classic Sullivan method weights each age interval's person-years by the prevalence of good health, so the resulting expectancy answers not just 'how long will people live?' but 'how many of those years will be healthy?'. It has become a headline summary of population health, reported by the World Health Organization as HALE and tracked alongside life expectancy to judge whether longer lives are also healthier lives.
