For sample adults ages 18 and older, BUTRTP reports the time unit (i.e., day, week, month, or year), which corresponds with the frequency with which the respondent reported eating butter on her/his food (e.g., on bread, rolls, or vegetables). Interviewers indicated to respondents not to include the use of margarine; margarine use was reported through a separate question later in the survey. BUTRTP should be used in conjunction with BUTRNO, which reports the corresponding frequency stated by the respondent. Researchers may also want to use BUTRSIZ, which reports the corresponding portion size.

BUTRTP is part of a series of variables initiated in 1987 related to food, food knowledge, and cancer. For related variables, please use the IPUMS NHIS search function and drop-down menus.


Changes in survey design (e.g., quarters in which the supplement was collected) may affect raw frequencies, but do not affect comparability of the variable. As always, data users should use the prescribed IHIS weights.
