Description

For sample persons ages 18 and over who have been tested for HIV (in 1990, who have ever been tested and whose last test was required; from 1991 to 1995, who have ever been tested; from 1997-1999, who have been tested for HIV in the last 12 months), ATRLMILIT reports if the reason for the most recent HIV test was because it was required for military induction, separation, or during military service. Beginning in 1993, respondents are asked not to include blood donations; from 1991 to 1993 " part of a blood donation process" was included as a separate response category; no instruction was offered for tests as part of blood donation in 1990. See the Comparability and Universe tabs for complete information on question wording and universe.

Comparability

Changes in universe and question wording affect comparability between samples. From 1991 to 1995, this question was asked of persons who have ever been tested for HIV. From 1997 to 1999, respondents were only asked this question if their most recent HIV test was within the last 12 months.

"Military induction, separation, or during military service" was part of a list of possible reasons the respondent could select for his or her most recent HIV test for 1994 forward. For 1990-1993, the response category read "For military induction or military service". Changes to the list between the 1991 and 1997 samples could affect comparability, although respondents were permitted to select more than one response from the list.

Changes in survey design (e.g. quarters or subsamples) affect raw frequencies but do not affect comparability between samples. As always, data users should apply prescribed IPUMS NHIS weights.
