Transcript of 1 Presentation to OG6 Canberra, Australia May 2011 Statistical Uses of Administrative Data in...
2
Overview of presentation
What is administrative data? Applications of administrative data Sources Advantages and disadvantages Examples of use in the energy statistics program
at Statistics Canada
3
What is administrative data?
Records collected and maintained by other government agencies to meet legislative or regulatory requirements:• To monitor activities related to the production and
consumption of energy• To enable regulatory or audit activities• To assess outcomes of policies, programs, initiatives• To register particular events (e.g. business
incorporations, licensing)
4
This differs from statistical data
Statistical records:• Are used to study dimensions, trends and
relationships of groups of persons or entities• Maintain the confidentiality of individual identifiable
information• Are used to produce aggregates, averages, measures
5
Applications of administrative data
Direct collection of data Substitution for survey data (e.g. for non-
response, for replacement of strata) Estimation, edits, imputation Creation and support of survey frames Data analysis, validation Improving timeliness
6
Sources of administrative data
Other government departments and agencies responsible for regulation, audit, evaluation• Can be national or sub-national
Can be made available through:• A file of individual records• Aggregated data• A survey or census of administrative agencies
7
Advantages of using admin data Reduction in the overall costs of collection Reduction in burden placed on respondents Greater availability of small area data Possible reduction in errors due to census
coverage Opportunities to link data to other admin sources Advances in technology make it easier, cheaper
to manipulate and use large data files Useful in the development of survey frames
8
Disadvantages of using admin data Admin data are not primarily collected for
statistical uses, which could lead to :• Inconsistent concepts, variables, definitions• Lack of follow-up, quality control• Possible breaks in series with changes to regulations,
legislation, policy• Non-representative population• Timeliness concerns
Does the statistical agency have a legal right to access? (Statistics Act)• Public concerns over confidentiality, intrusiveness?
10
For direct collection
Where survey data do not exist Eg. Deregulation of the energy market created
secondary distributors• Data collected from natural gas distributors and
transporters on sales to residential, commercial and industrial sectors
• A proxy for consumption data Eg. Import and export data from the National
Energy Board• From admin files on permits
11
For direct collection
As a supplement for existing data Eg. For monthly crude oil and natural gas
production, imports, exports, domestic deliveries and inventories, data are collected through both survey & admin data• Producing provinces gather regulatory data
12
As a substitution for survey data
Eg. Electric Utility Financial Report gathers an annual breakdown of a series of balance sheet and income statement items• In 2008, negotiated with Ontario Energy Board to
gather aggregate admin data for 85 municipal respondents
• Reduced costs, burden
13
For estimation, edits, imputation
Where data are missing, incomplete, inconsistent with historical data
Eg. Missing fuel consumption values are calculated using the change in fuel consumption by industry
14
To support survey frames
All energy surveys recently hooked up to the Statistics Canada Business Register
A good source of information to establish and maintain survey frames
Promotes harmonization across department
15
For data analysis and validation
Energy statistics program uses other sources of information for quality control, outlier detection, confrontation
Examples:• Reports from industry associations• Reports from other government departments
16
For improving timeliness
Program is working to accelerate the collection and reporting of key petroleum production data• Using data from the Petroleum Registry of Alberta
(PRA) as a starting point, to eliminate duplicate reporting
• PRA collects data for regulatory purposes • The application may be extended to other producing
provinces
17
For the future...
Other applications under investigation:• Tax data, to replace financial reporting• Public sector statistics, for data on electric utilities –
operating revenues and expenditures, sales of electricity, using income statements and balance sheets Currently assessing survey data vs admin
18
Conclusion
Statistics Canada is relying more on admin data Driving factors: fiscal restraint, evolving
technology, respondent burden Success based on legislative authority +
ongoing collaboration Need to be aware of the constraints and
challenges of using admin data
