CORRECTION AND UPDATE INFORMATION:

It has been brought to our attention that a recent information and
availability release by NACDA regarding the THE NATIONAL SURVEY OF MIDLIFE
DEVELOPMENT IN THE US (MIDUS) contained two information errors.  The
following corrections are being made to the release information provided in
December of 1999.

1) Funding Source:
THE NATIONAL SURVEY OF MIDLIFE DEVELOPMENT IN THE US (MIDUS) IS FUNDED BY
THE JOHN D. AND CATHERINE T. MAC ARTHUR FOUNDATION.  

The December release mistakenly attributed funding to the United States
government in the front heading rather than The Jonh D. and Catherine T.
MacArthur Foundation as referenced in NOTE (2) of the release information.

2) Twin Data Information: (PART 3)
The section should be corrected to read:
PART 3, TWINS DATA, PRESENTS DATA FROM A NATIONALLY REPRESENTATIVE SURVEY
OF 1,996 TWINS.  THE TWIN RESPONDENTS WERE GIVEN THE SAME ASSESSMENTS AS
THE MAIN AND SIBLINGS SAMPLES. 

The data release abstract mistakenly reported that the twin sample was
drawn from the Main Respondents files.

NACDA appreciates the input of researchers who observed these discrepancies
and apologizes for any inconvenience this may have caused.  We encourage
the research community to address any concerns or questions regarding data
on aging to NACDA at NACDA at icpsr.umich.edu
