For sample adults, PORKYR is a recoded variable that reports how many times per year the person consumed pork, including pork chops or roasts. This recoded variable is based on the responses to PORKNO, which reports the frequency with which the person ate pork, and PORKTP, which reports the corresponding time unit. For information about the portion size, see PORKSIZ.

In 2010, the variable REDMEATMNO was introduced, which reports how many times the person ate red meat, such as beef, pork, ham, or sausage.

PORKYR 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.
