Codes and Frequencies
For sample persons age 18 and over, SMKRISKPREG reports if the person agrees/disagrees that smoking by a pregnant woman may harm the baby.
For related variables, please use the IPUMS NHIS search function and drop-down menus.
Apart from changes in the universe, this variable is mostly comparable over time. Slight changes in the response categories may also affect comparability. Changes in survey design (e.g., quarters in which the supplement was collected) may affect raw frequencies. As always, data users should use the prescribed IHIS weights.
