In 1941-1954, men were asked, "Do you smoke cigarettes?" In 1955-1959, respondents were asked, "Do any men [women] in your household smoke cigarettes with [without] a filter tip?" In 1960-1965 and 1967, women and men were asked, "Have you bought, for your own use, cigarettes with [without] a filter tip in the past 30 days?" In 1966 and 1968-1979, women and men were asked, "Have you bought, for your own use, cigarettes with [without] a filter tip in the past 7 days?" Data since 1955 are based on the sum of the percentage of smokers who bought filter-tipped cigarettes and the percentage who bought nonfilter-tipped cigarettes in the past 30 days
