Description

The main purpose of this data is to monitor cigarette smoking in Canada and attempt to measure the effect of cigarette price reductions on smoking behaviour. This survey is also used to measure the prevalence and the amount of cigarettes smoked and to monitor any changes during this time. The information collected in this survey will allow Health Canada to make the best use of its funding when planning its programs and policies over the next several years.

Data sources and methodology

Sampling

This is a sample survey with a cross-sectional design.

Data sources

Responding to this survey is voluntary.

Data are collected directly from survey respondents.

A sample of telephone numbers was generated at random from the RDD system used by GSS. Telephone numbers were dialled and screened to determine if they belonged to households. For all household telephone numbers, the ages of the household members were listed and one person aged 15+ was selected at random. The selection of the one household member gave greater probability of selection to ages 15-24 and ages 65+ than to ages 25-64. After reaching the largest sample size of households having all members in the 15-64 age range, the remaining such households were screened out of the sample. The selected person was then interviewed (non-proxy only). For the second and subsequent cycles, the respondents from the first cycle were re-contacted. In cycle 2 an attempt was made to reach all 15,804 original respondents. For those who had changed telephone numbers, attempts were made to reach the person at a work telephone number (if given) or to reach the "contact" person to ask for the respondent's current phone number. In cycles 3 and 4, interviewers attempted to contact 14,453 of the original respondents; the exclusions being those people who could not be located in cycle 2 or who refused the cycle 2 interview.

Estimation

Initial weights were calculated as the inverse probability of selecting a telephone number. These initial weights for households were adjusted for non-response at the household level and for the number of distinct telephone numbers for the household to give a basic household weight. The household weight was then adjusted by the inverse probability of selecting the "selected respondent" and adjusted for non-response of that selected person. The final stage of weighting was post-stratification to population totals by province, sex and age group.

Disclosure control

Statistics Canada is prohibited by law from releasing any information it collects which could identify any person, business, or organization, unless consent has been given by the respondent or as permitted by the Statistics Act. Various confidentiality rules are applied to all data that are released or published to prevent the publication or disclosure of any information deemed confidential. If necessary, data are suppressed to prevent direct or residual disclosure of identifiable data.

Data accuracy

Response rate was somewhat lower than expected, but there is no indication that non-response was correlated with smoking behaviour.
