background to the integrated approach
Background to the Integrated Approach
  • Established in 1997
  • Goal to integrate all annual business surveys
  • Objectives:
          • Improve coherence
          • Improve breath and depth of data
          • Not increase response burden
  • Created one central area for processing (ESD)
integrated approach principles
Integrated Approach Principles
  • Use of a single unduplicated frame -- the BR
  • Common sample design methodology
  • Questionnaire
          • harmonized concepts / variables
          • Generic portion
  • Centralized Data Collection
integrated approach principles continued
Integrated Approach Principles (continued)
  • Integrated metadata system
  • Common generic processing systems and methods (all residing in ESD)
  • Centralized data warehouse
  • Head Office Survey
  • Maximum use of tax data
  • Coherence analysis for large enterprises
  • Regular profiling of large enterprises
  • Holistic approach to response management
survey characteristics
Survey Characteristics
  • All annual surveys
  • Establishment Surveys
  • Currently 64 surveys but plans to add more
  • Smallest businesses estimated through tax
sampling
Sampling
  • Stratified Random Sample
    • Industry
    • Province
    • Size
      • 1 Take-all stratum
      • 2 Take-some strata (50% of units replaced by tax)
      • Take-none strata
sampling process

T1

Main sample to be surveyed

(sample size of about 47k, from which 4k are T1)

Sample substitution (TRP) for pre-identified T1 (unincorporated) and T2 (Incorporated) units.

centralized processing systems and databases
Centralized Processing Systems and Databases
  • Develop centralized systems
        • Single point of access for security
        • Move away from stand-alone
        • Increase efficiency of resource use
  • Integrated Questionnaire Metadata System
  • Edit and imputation
        • Use generalized system
  • Allocation
        • Developed for complex units
        • In the process of standardizing the approach
  • Estimation

ues use of tax data in post collection
UES: Use of Tax Data in Post-Collection
  • Validation (comparison)
      • Verify dubious collected data against it’s equivalent tax data record
  • Imputation
      • One of the methods used for non-response
  • Estimation
      • Weighted TRP units, T2 take-none, weighted T1 take-none, T1 adjustments for units not on the business register
ues use of tax data in post collection continued
UES: Use of Tax Data in Post-Collection (continued)
  • Not always a direct correspondence between tax and survey variables: differences in concepts and definitions
  • Developed a common mapping to bring them together
        • Standard income statement called Chart of Accounts
        • Map survey and tax data to it
analysis and dissemination
Analysis and Dissemination
  • Analysis conducted by subject-matter specialists
  • Use of common analytical tools
  • Estimates released no later than 15 months after reference date
  • Previous year’s data is revised when working on current year
achievements
Achievements
  • Timeliness improved
  • Efficient, streamlined systems
  • Common database
  • Response burden reduced
  • More coherent data
  • More efficient use of resources
