Continuity Measures for Statistics Canada’s Longitudinal Business Database

Statistics Canada
The Business Register (BR) at Statistics Canada provides monthly snapshots of the Canadian economy with a list of active businesses and auxiliary data from various administrative sources. Economic and classification variables are used in survey programs to create frames and collect relevant information from respondents to fulfill business statistical programs requirements. Analysts are responsible for understanding the changes in their population from one period to the next by tracking specific business transformation events like mergers, acquisitions and splits. The Longitudinal Business Database (LBD) currently being developed will reduce this burden by providing the users of the BR with more information on businesses longitudinal changes. The LBD will offer tables of events with effective dates, longitudinal identifiers with graphical tools to visualize continuity and other useful data which will be used to increase the amount of business demography statistics produced. This presentation will focus on the continuity rules like labour tracking and metadata comparison as well as the combined score function used to establish links between businesses over time.
