HRS ADAMS 1 data (Early, Version 4.0) are now available.

The ADAMS Version 4.0 Early data release of January 2009 includes eight newly-released files, ADAMS1AF_R, ADAMS1AF_SB, ADAMS1AF_CH, ADAMS1AJ_R, ADAMS1BF_R, ADAMS1BF_SB, ADAMS1BF_CH, and ADAMS1BJ_R. These files include information obtained at the initial and follow-up assessments about family history, dementia checklist, and neurological exam data. Also included are all previously released files.

In November 2007, the Section AA file, ADAMS1AA_R, was revised and re-released as Version 1.1 to include a new weight variable, AASAMPWT_F and a new education variable, EDYRS, which included a revised value for two respondents; the prior education variable, SCHLYRS, was dropped. The technical report describing the development and use of the sample weights was updated. The changes are described in section 5.D.3 (p. 23-24) of the report. A revised report is available here:

No changes have been made to other previously released files, section AB, AD, AN, AG, BB, BD, BN, and BG files, released as Version 1.0 in February 2007, section E files AE_D, AE_R, BE_D, and BE_R, released as version 2.0 in August 2008, or section files AH, AM, BH, and BM released as version 3.0 in November 2008.
