1. UES Background
Major project to improve provincial statistics
(1996)
Reliable Annual Provincial Data for the
Allocation of HST Revenues (SNA I-O Tables)
More detailed Industry & Commodity data
Creation of Enterprise Statistics Division
(ESD)
UES Pilot (RY 1997) -- 7 surveys
Gradual Expansion of Surveys; Covers 65% of
GDP
2. Integrated Approach Principles
Use of Single, Unduplicated Frame -- the BR
Expanded coverage
Common Sample Design Methodology
Integrated Questionnaire -- common /
simple language; harmonized concepts /
variables
Centralized Data Collection at the Statistical
Establishment level
2. Integrated Approach Principles
(continued)
Common Generic Processing Systems and
Methods
Centralized Warehouse
Head Office Survey
Maximum Use of Tax Data
Annual Profiling of Large Enterprises
Enterprise Portfolio Managers
3. Survey Characteristics
Separate Enterprise & Establishment
Surveys
Over 50 Establishment Surveys
Over 55,000 collection entities representing
about 68,000 establishments (17K replaced
by tax for RY 2005)
Centralized Collection -- $3.5 million
budget
Smallest businesses estimated through tax
4. Business Register (BR)
BR covers all sectors
Incorporated and unincorporated
businesses
Complex and simple enterprises
Structure
Legal
Operational
Statistical (Enterprise & Establishment)
Updated with Administrative Data
5. Sampling
Stratified Random Sample
 Industry (NAICS 4)
 Province
 Size
1 Take-all stratum
2 Take-some strata (50% of units replaced
by tax)
Take-none strata (under Royce-Maranda
thresholds)

6. Achievements
Timeliness
Centralized Processing Systems
and Databases
Response Burden
Use of Tax Data
6a. Timeliness
Very problematic during start-up years
Many processing systems in development
Problems with questionnaires
Task force created in 2001
Target: 15 months after reference year
Since RY 2003, all surveys between 12-15
month period
6b. Centralized Processing Systems
and Databases
Develop centralized systems
 Move away from stand-alone
 Single point of access for security
Integrated Questionnaire Metadata System
Edit and imputation
Allocation and Estimation
Data Warehouse

7. Use of Tax data
Significant process since 1997
Strategic Streamlining Initiative
Result
Almost 65% of units replaced by tax data
Impact of 27% in the total estimate
Streamlining Initiatives at STC
Announced in 2002
Objectives
Maintaining quality
Create efficiencies
Enhance work flows
Identify trade-offs
Expand the use of tax data for survey
replacement
T1\T2 Project
Objective is to substitute 50% of simple
establishments.
Direct Data Replacement for annual
surveys using
T1(unincorporated)
T2 (incorporated)
Facilitated by the Chart of Accounts
(COA).
Types of Administrative (Tax) Data
From the Canadian Revenue
Agency (CRA)
Agreement between CRA and STC
T1 (unincorporated businesses)
T2 (incorporated businesses)
T4 (pay slips)
GST (goods and service tax)
PD7 (payroll deduction accounts)
Processing of Tax Data
Edit erroneous reports
Outlier detection
Eliminate duplication
Impute for missing values
Annualize in case of monthly data

UES: Use of Tax Data
 Validation (comparison)
Verify dubious collected data against the
equivalent tax data record
 Imputation
One of the methods used for non-response
 Estimation
Below take-none
Direct Data Replacement
Some annual surveys 100% tax (Taxi &
Limousines, Survey of Mapping)
 Update Business Register
 Allocation of survey data ( use tax revenues, salaries
and expenses)
