classified as "tuna users." Those who had 

 used canned tuna in the past 12 months but 

 not within the li-week period were termed 

 "sporadic users" . 



The tuna users were further divided 

 into light and heavy user groups. The 

 "li^^ht users" are defined as those who 

 used tuna one or two trries in the h weeks 

 imnediatsl.Y prior to the interview and the 

 "heavy users" as those who had served it 

 three tl-nes or more in this period. The 

 distribution of these user groups in the 

 three cities is sumarized in the following 

 table. (Note; The reader should keep in mind 

 while reading the following text and tables 

 that "tuna-users" are by definition all 

 respondents representing households who had 

 used canned tuna within the l^-week period. 

 The tern., therefore, includes both li£ht 

 users and heavy users.)
