Overview of presentation § § § 2 What is administrative data? Applications of administrative data Sources Advantages and disadvantages Examples of use in the energy statistics program at Statistics Canada

What is administrative data? § Records collected and maintained by other government agencies to

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) 3

This differs from statistical data § Statistical records: • Are used to study dimensions,

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 4

Applications of administrative data § Direct collection of data § Substitution for survey data

Applications of administrative data § Direct collection of data § Substitution for survey data (e. g. for nonresponse, for replacement of strata) § Estimation, edits, imputation § Creation and support of survey frames § Data analysis, validation § Improving timeliness 5

Sources of administrative data § Other government departments and agencies responsible for regulation, audit,

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 6

Advantages of using admin data § § Reduction in the overall costs of collection

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 7

Disadvantages of using admin data § Admin data are not primarily collected for statistical

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? 8

For direct collection § Where survey data do not exist § Eg. Deregulation of

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 10

For direct collection § As a supplement for existing data § Eg. For monthly

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 11

As a substitution for survey data § Eg. Electric Utility Financial Report gathers an

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 12

For estimation, edits, imputation § Where data are missing, incomplete, inconsistent with historical data

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 13

To support survey frames § All energy surveys recently hooked up to the Statistics

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 14

For data analysis and validation § Energy statistics program uses other sources of information

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 15

For improving timeliness § Program is working to accelerate the collection and reporting of

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 16

For the future. . . § Other applications under investigation: • Tax data, to

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 17

Conclusion § Statistics Canada is relying more on admin data § Driving factors: fiscal

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 18
