Recent smokers are defined to be persons who reported smoking at the previous interview wave and recent quitters are defined as persons who reported smoking at least once during prior waves and reported having quit smoking by the previous interview wave. Ever smokers are those who have reported smoking sometime in their life. In this table we list the means for the person-wave observations; in Table 1 the means were for persons in Wave 1 who were ever smokers.
