Canadian Business Patterns, December 2004 [B2020]

The Canadian Business Patterns contains data that reflects counts of business locations (as of December 2008) and business establishments (prior to December 2009) by: 9 employment size ranges, including \"indeterminate\" (as of December 1997); geography groupings: province/territory, census division, census subdivision (before December 2008), census metropolitan area and census agglomeration; and industry using the North American Industry Classification System (tables at the 2, 3, 4 and 6-digit level) as of December 1998. Before December 2004, these data were also presented using the Standard Industrial Classification (tables at the 1, 2, 3 and 4-digit level). The data published in the Canadian Business Patterns represents the current number of locations or establishments for a specific reference period which is taken from the Business Register Central Frame Data Base. It is not intended for use as a time series because changes that affect the continuity of the data might resu lt from changes in methodology. Some examples are: the change to another version of the Standard Geographical Classification (SGC) or the North American Industry Classification System (NAICS), the addition of the new territory of Nunavut and new rules to better identify inactive units.

《加拿大商业格局》（Canadian Business Patterns）数据集收录了两类统计数据：截至2008年12月的商业网点计数，以及2009年12月之前的商业机构计数。其分类维度包含三部分：其一为9类雇佣规模区间（含1997年12月统计的“雇佣规模无法确定”类别）；其二为地理分组，具体包括省/领地、普查分区（Census Division, CD）、普查细分区域（Census Subdivision, CSD，2008年12月之前采用该分类）、普查都会区（Census Metropolitan Area, CMA）及普查集聚区域（Census Agglomeration, CA）；其三为行业分类，1998年12月起采用北美行业分类系统（North American Industry Classification System, NAICS），对应2、3、4、6位码层级的统计表格。2004年12月之前，该数据集曾采用标准行业分类（Standard Industrial Classification, SIC），对应1、2、3、4位码层级的统计表格。
本数据集发布的《加拿大商业格局》数据取自商业登记中央框架数据库（Business Register Central Frame Data Base），反映特定参考周期内的当前网点或机构数量。由于方法论变更可能影响数据连续性——例如标准地理分类（Standard Geographical Classification, SGC）或北美行业分类系统版本更迭、新增努纳武特地区、增设用于更精准识别非活跃经营单位的新规则等——本数据集不适合作为时间序列使用。
