Canadian Tobacco Use Monitoring Survey, 1999: Annual, Household File

The Canadian Tobacco Use Monitoring Survey was administered between February 1 and December 30, 1999 as a random digit dialling (RDD) survey, a technique whereby telephone numbers are generated randomly by computer. Interviewing was conducted over the telephone. The sample design is a special two-phase stratified random sample of telephone numbers. The two-phase design is used in order to increase the representation in the sample of individuals belonging to the 15-19 and 20-24 age groups. In the first phase, households are selected using RDD. In second phase, one or two individuals (or none) are selected based upon household composition. Because the main purpose of the survey is to produce reliable estimates in all ten provinces, an equal number of respondents in each province is targeted. It was estimated that a total of about 148,000 telephone numbers per year will be needed to get the 20,000 respondents per year. This assumed a 75% response rate and about 20% of households having individuals aged 15-24; the hit rate varies substantially by province, with an expected overall average of about 43%. There were 45,106 respondents to the 1999 (Annual).
