LASA

Cognitive functioning and aging

In the table below, entries in the left column refer to the related documentation, while the numbers in the cells of columns LASA-B to LASA-I refer to the corresponding LASA-data files (e.g. '022' in column B-G refers to 'LASAB022', 'LASAC022', 'LASAD022', 'LASAE022', 'LAS2B022', and 'LASAG022' respectively). Underlined entries are hyperlinks, hovering with your mouse over the underlined wave names will show you the years in which the corresponding measurements took place.

* Files in the 700 series contain data from telephone interviews held with respondents, while files in the 600 series contain data from telephone interviews held with proxies. In wave C however, the same questionnaire was used for both respondent and proxy; data was stored in the 600 series.
