For female sample persons who have ever had a mammogram, MAMLIFFREQ reports the number of times she has had a mammogram in her lifetime.
Please use the IPUMS NHIS drop down menu and search functions for related variables.
Apart from changes in the universe, there are no comparability issues. Changes in survey design (e.g., quarters in which the information was collected) may affect raw frequencies, but do not affect comparability of the variable. As always, data users should use the prescribed IHIS weights.
