Data sources and methodology

Target population

The annual Mushroom Growers' Survey is a census of all mushroom growers with area over 100 square feet. The population of mushroom growers is derived from the Census of Agriculture, supplemented by administrative data from various sources.

The target population is all mushroom growers with area over 100 square feet that meet Statistics Canada's definition of a farm. A farm is defined as an operation that produces at least one agricultural product and will report revenue and/or expenses for that agricultural production to the Canada Revenue Agency. Institutional farms and community farms are excluded from the target population.

The observed population consists of establishments on Statistics Canada's Business Register that represent this target population. This frame of operations is derived using signals of agricultural activities on the latest set of tax declarations. To improve the overall coverage of this frame to the target population, information from additional sources including lists of special operations and survey feedback is used to include establishments which report their fiscal data differently.

Sampling

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

Data are collected for all units of the target population, therefore, no sampling is done.

Data sources

Responding to this survey is mandatory.

Data are collected directly from survey respondents and extracted from administrative files.

100% follow-up by phone is done for non-respondents to the mailed questionnaire. The current questionnaire is paired with the previous year's form. For any problems or large changes, telephone follow-ups are conducted. All editing of data is done manually. Data are compiled on micro-computer. Fraser Valley Cooperative and Pacific Fresh Mushroom Co-op provide only area and sales for its British Columbia members. Other data are obtained from the B.C. questionnaires. Generally, it is not required to revise the data due to follow-up procedures for non-respondents.
