Codes and Frequencies
For sample adults, FRYFISHTP reports the time unit (day, week, month, or year) that corresponds with the frequency with which the respondent reported eating fried fish or fish sandwiches. FRYFISHTP should be used in conjunction with FRYFISHNO, which reports the corresponding frequency stated by the respondent. For information about the portion size, see FRYFISHSIZ.
FRYFISHTP 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.
Apart from changes in the universe, there are no comparability issues. 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.
- 1987: Half of sample persons age 18+ (excluded from CACT supplement).
