What is the main objective of ELSA?

The aim of ELSA is to explore the unfolding dynamic relationships between health, functioning, social networks and economic position. It is in effect a study of people's quality of life as they age beyond 50 and of the factors associated with it.

How often are people interviewed for the survey and who is interviewed?

A sample of people over the age of 50 are interviewed every two years. The ELSA sample was selected from three survey years of the Health Survey for England (1998, 1999 and 2001). Households were included in ELSA if they contained at least one adult of 50 years or older in the household who had agreed to be recontacted at some time in the future.

What formats are the data available in?

The data are available in SPSS, Stata, SAS and ASCII tab-delimited formats.

Where can I obtain statistics and tables from ELSA?

Downloadable reports are available on the IFS Publications web page.

Details of publications are given in the ELSA resources section of the Guide to the English Longitudinal Study of Ageing.

What is the most detailed regional level I can analyse the data at?
