The Economic and Social Data Service (ESDS) were funded to compile this teaching dataset by the Economic and Social Research Council (ESRC) and Joint Information Systems Committee (JISC).

The National Institute of Aging, the Department of Health, the Department for Work and Pensions, the Office for National Statistics, the Department for Environment, Food and Rural Affairs, the Department for Transport, the Department for Education and Skills, the Department for Culture, Media and Sport and HM Treasury funded the main English Longitudinal Study of Ageing, from which this dataset has been compiled.

Abstract:
The ELSA teaching data file contains information obtained from individual interviews and self-completion questionnaires from all 12,100 ELSA participants.

The file contains less than a tenth of the number of variables available on the main ELSA file and is designed for use as a teaching aid and also as a sampler for new and potential users of the main data.

Variable names are the same as those on the original ELSA dataset, held under SN 5050.


Main Topics:
The individual interview comprised the following twelve modules:

Coverage:
Time Period Covered: Most of the data refers to the time period when the interview took place. Some of the questions however did ask about past events (e.g. pension history, the participant's father's job when he/she was 14 years old).
Dates of Fieldwork: March 2002-March 2003.
Country: England
Spatial Units: At present the ELSA team are not depositing any variables which will allow analysis by or on spatial units. However, they are developing a system by which these data could be provided to researchers who want to use it. Various methods of providing access to these data are currently being considered, including specialised datasets and data enclaves. In order to obtain access to these data, researchers will need to provide details of the analysis they wish to do and sign an agreement stating that they would use the data appropriately.
Observation Units: Individuals
Kind of Data: Numeric data; Individual (micro) level

Universe Sampled:
Location of Units of Observation:National
Population:The ELSA sample was selected from three survey years of the HSE (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 re-contacted at some time in the future. Wave 1 of ELSA was conducted between March 2002 and March 2003.

Methodology:
Time Dimensions: Longitudinal/panel/cohort
Wave 0 (HSE - baseline) has not yet been deposited. The current deposit comprises Wave 1. Data collection is currently in progress for Wave 2, and Waves 3 and 4 are in development.
Sampling Procedures: Multi-stage stratified random sample
Number of Units: Target: 18813 (17768 core sample members and 1045 younger partners). Obtained: 12100 (11392 core sample members, 72 new partners and 636 younger partners). Weighted: 11392 (core sample members only).
Method of Data Collection: Face-to-face interview; Self-completion
Weighting: Weighting used. See documentation for details.
Data Sources: The ELSA sample was selected from three survey years of the HSE: 1998 (held at the UK Data Archive under SN 4150), 1999 (SN 4365) and 2001 (SN 4628). Some HSE variables are included in the ELSA dataset.
