Data sources and methodology

Target population

The target population for the survey is non-institutionalized persons 15 years of age or older living in Canada's ten provinces.

Instrument design

The content for the National Cannabis Survey electronic questionnaire was drafted in consultation with the System of National Accounts team within Statistics Canada as well as several other federal government departments and agencies, including the survey sponsor, Health Canada, the Public Health Agency of Canada, Public Safety Canada and the Department of Justice of Canada.

The questionnaire was subject to cognitive testing in the form of in-depth interviews in both of Canada's official languages, conducted by Statistics Canada's Questionnaire Design Resource Centre. The goal of the qualitative study was to test the survey content.

Sampling

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

Frame:
The frame is the Dwelling Universe File. Institutions, collective dwellings and dwellings on Indigenous reserves were excluded.

Sampling unit:
The NCS sample has a two-stage design: the sampling unit for the first stage is the dwelling, and the sampling unit for the second stage is the person.

Stratification method:
The NCS frame was stratified by province, and a simple random sample of dwellings was selected independently within each province.

Sampling and sub-sampling:
Sufficient sample was allocated to each of the provinces so that the survey could produce provincial level estimates. An initial sample of 12,000 dwellings was selected and sent to collection.
