The English Longitudinal Study of Ageing (ELSA) is a longitudinal study that collects multidisciplinary data from a representative sample of the English population aged 50 and older. The survey data are designed to be used for the investigation of a broad set of topics relevant to understanding the ageing process including economic position, physical and mental health, labour market activity, retirement and social networks.

Sample details
Sample members are drawn from respondents to the Health Survey for England (HSE). Around 12,000 respondents from three separate years of the HSE survey were recruited to provide a representative sample of the English population aged 50 and over and their partners. At waves 3, 4, 6 and 7 the study was replenished with new study participants (refreshments) from HSE to maintain the size and representativeness of the panel.
