Codes and Frequencies
For sample persons aged 18 and older (in 1987, who have ever heard of AIDS), AIDTESTKNOW indicates if the person has ever heard of a blood test that can detect the AIDS virus infection.
This variable is part of the NHIS supplement on AIDS knowledge and attitudes. For related variables, please use the IPUMS NHIS search function and drop-down menus.
Changes in universe affect comparability between 1987 and subsequent years.
Changes in survey design (e.g., quarters in which the supplement was collected) in 1988 onward may affect raw frequencies, but do not affect comparability of the variable. As always, data users should use the prescribed IHIS weights.
