Next, a list of all the dwellings in the selected clusters is prepared and a sample of dwellings is selected within each cluster. It is essentially a two-stage design, of which the first stage is to select a sample of geographic areas (the clusters). In the three territorial capitals, the sampling unit is the dwelling.Ī stratified multi-stage sampling design is used to select the first sample in the 10 provinces. For the second sampling design, the sampling unit is directly the dwelling. In the second stage, the sampling unit is the dwelling. For the first sampling design (which is a two-stage design), the sampling unit at the first stage is the geographical area (called a cluster). This is a sample survey with a cross-sectional design.įor SHS 2021, in the 10 provinces, the final sample was obtained from two distinct sampling designs. The diary was sent to respondents by mail. In 2021, SHS collection moved from a computer-assisted personal interviewing (CAPI) to a self-completed questionnaire (EQ) following the health measures restrictions of the COVID 19 Pandemic. When changes have been made, the content has been re-tested using cognitive interviews and updated based on the feedback received. The content of the questionnaire and changes to it have been determined in consultation with primary internal and external users of the survey data. These studies were based on the data from the Consumer Expenditure Survey conducted by the U.S. The choice of recall period for each item was largely based on the results of qualitative tests, on international best practice and on studies of estimate variability when reference periods were shortened. For the questionnaire items, a recall period of one, three or twelve months, last payment, or four weeks, was also selected. When this new collection model was introduced, each of the expenditure items covered by the SHS was assigned to a collection mode: questionnaire, expenditure diary or both. These expenditures may be more difficult to recall. The diary is used to collect expenditures for smaller, less valuable items and those purchased more frequently. The questionnaire is generally used to collect expenditures for more expensive, and less frequently purchased goods and services. Since 2010 in the provinces and 2015 in the three territorial capitals, the SHS data have been collected using both a questionnaire and an expenditure diary. However, these people are included in the population estimates to which the SHS estimates are adjusted. members of religious and other communal colonies.Ĭollection exclusions make up less than 0.5% of the target population. people living permanently in school residences, work camps, etc. people living in residences for dependent seniors Also excluded, in addition to people living in institutions, are people living in other types of collective dwellings: In all, these exclusions account for about 2% of the population.įor operational reasons, people living in some remote areas where the rate of vacant dwellings is very high and where the collection cost would be exorbitant, are excluded from collection. The target population is the population of Canada's 10 provinces, as well as the territorial capitals of Whitehorse, Yellowknife and Iqaluit, excluding residents of institutions, members of the Canadian Forces living in military camps and people living on Indian reserves. Subjectsĭata sources and methodology Target population Various groups also use the data to address issues directly or indirectly related to Canadians' spending habits.Ĭollection period: The data are collected on a continuous basis from January to December of the survey reference year, from a sample of households spread over twelve monthly collection cycles. In addition, federal and provincial governments use the data to develop social and economic policies and programs. SHS data are used at Statistics Canada by the Canadian System of Macroeconomic Accounts as an input to calculate Gross Domestic Product (GDP) and by Consumer Prices Division to calculate basket weights for the Consumer Price Index (CPI). The SHS is conducted in the 10 provinces and the 3 territorial capitals every 2 years starting with the 2017 reference year. It also collects information about the annual income of household members (from personal income tax data), demographic characteristics of the household, dwelling characteristics (e.g., type, age and tenure) and household equipment (e.g., electronics and communications equipment). The SHS primarily collects detailed information on household expenditures. Questionnaire(s) and reporting guide(s).The main purpose of the Survey of Household Spending (SHS) is to obtain detailed information about household spending, as well as limited information on dwelling characteristics and household equipment.
