• Data is age adjusted– Age adjustment relates to standardizing the data

to 2000 U.S. Standard Population.  Many health outcomes / behaviours relate to age. Age adjustment compares attributes of groups whose age distributions may be different.

– Example: smoking rates in men and women. Since the women sampled in the CHS were older, age adjustment must be taken into account
