Note: IADL (instrumental activity of daily living) only means inability to perform at least one IADL, but no help or equipment use for any ADL (activity of daily living). Those with ADLs may be using equipment or receiving either active or standby help.
Produced by Center for Demographic Studies for Federal Interagency Task Force on Aging-Related Statistics, Older Americans 2000: Key Indicators of Well-Being (http://www.agingstats.gov).
Estimates reproduced from Older Americans 2000 apparently include light housework, laundry, meal preparation, grocery shopping, getting around outside, financial management, using the telephone, taking medications, and transportation. Spillman estimates include the same items, except transportation.
IADLs apparently include all in Older Americans 2000.
The final weight is poststratified to Census totals using methodology consistent with that described in Census weighting specifications for the 1989 and 1994 survey waves. Cell counts for persons who are neither in an institutional residence nor disabled at screen and those who receive the community questionnaire but are not in any type of group quarters are adjusted to cell counts by age, gender, and race for the civilian noninstitutional population. Cell counts for persons who are disabled and living in noninstitutional group quarters (i.e., living with three or more unrelated individuals), those living in an institutional setting that does not have medical staff on duty daily, and those receiving the institutional questionnaire (i.e., those living in group quarters, including institutional settings, that have medical staff available daily) are adjusted to age, race, and gender for a population defined as the civilian population, excluding the civilian noninstitutional population and the population in correctional facilities. Persons in correctional facilities are out of scope.
