Initiatives -
To understand all aspects of ageing in people of England. The primary objectives of ELSA were to design and implement data collection on a population aged 50 or older at inception, and to document and distribute the data that are produced. Specific issues addressed were: 1. Health trajectories, disability and healthy life expectancy; 2. The relationship between economic position and health; 3. The determinants of economic position and economic activity at older ages; 4. Social networks, support, and participation; 5. Household and family structure, and the transfer of resources.
