1 Metadata: Integral Part of Statistics Canada Quality Framework International Conference on Agriculture Statistics October 22-24, 2007 Marcelle Dion Director General, Agriculture, Technology and Transportation Statistics, Statistics Canada

2 Outline Quality Assurance Management Integrated Metadata Base Application to Agriculture Statistics

3 Statistics Canada’s Quality Assurance Management Three key elements: Quality Assurance Framework Policy on Informing Users of Data Quality and Methodology Integrated Metadata Base

4 Quality Assurance Framework Defines quality as “fitness for use” Identify six indicators of “fitness for use” Relevance, accuracy, timeliness, accessibility, interpretability and coherence Metadata: at the heart of the management of the interpretability indicator Interpretability refers to the provision of information that help users understand the data released by Statistics Canada

5 Policy on Informing Users of Data Quality and Methodology One of the policies that governs Statistics Canada Requires all statistical outputs to have information (metadata) on: Concepts and definitions Methodology used to produce the data Data accuracy Defines standards and guidelines Identifies responsibilities

6 Integrated Metadata Base Definition of Metadata Characteristics of the Data Base Governance Policy Technical Assistance Monitoring Access

7 Definition of Metadata Metadata inform users of the features that affect the quality of all data published by Statistics Canada. provide a better understanding of the strengths and limitations of data, and how they can be effectively used and analyzed are of particular importance when making comparisons with data across surveys or sources of information in drawing conclusions regarding changes over time differences between geographic areas differences among sub-groups of the target populations of surveys breed users’ trust

8 Integrated Metadata Base Characteristics Corporate repository of metadata Metadata for 415 active and 400 inactive surveys (discontinued or one time) Metadata for any survey instance since November 2000 Easily accessible online: Metadata complies with policy Minimum requirements

9 Metadata: Policy’s Minimum Requirements

10 Integrated Metadata Base Governance Policy ensures compliance Policy ensures coherence Policy defines accountability Managers of program areas Methods and Standards Committee Standards Division responsible for management

11 Integrated Metadata Base Technical Assistance Metadata Officers Guidelines for author Template

12 Template – One Section Data Sources – Type of Surveys Please highlight the terms that apply to this survey (more than one source may apply) Direct – data are collected directly from STC respondents with the use of a collection instrument Administrative - data are extracted from administrative files provided by an external organization that collected them for reasons other than statistical purposes Derived – Data were derived from other Statistics Canada programs or surveys and/or other sources (e.g. media, annual reports) --------------------------------------------------------- Census – the intent is to collect information from all units of the survey population Sample – information is collected from only a fraction of units of the survey population ---------------------------------------------------------- Longitudinal – the same statistical units are followed over time Cross-sectional – the statistical units are specific to one point in time Cross-sectional with longitudinal follow-up – the statistical units which are specific to one point in time are also followed over time ----------------------------------------------------------- Mandatory – respondents are required, under the Statistics Act, to answer all the survey questions Voluntary – respondents may refuse to answer some or all of the survey questions

13 Integrated Metadata Base Quality Monitoring Triggers for creating or updating records Information loading: Template Metadata officers’ review Identify program areas needing assistance Exhaustive review - Four-point scale Official notice to program areas’ managers

15 Agriculture Statistics Description of the program Framework Metadata

16 Program Description Monthly, quarterly, annual and/or seasonal data collection activities related to crop and livestock and farm finances as needed Quinquennial Census of Agriculture with the Census of Population Economic series on the agriculture sector System of National Accounts (SNA) and agriculture GDP Administrative data supplement limited survey taking in supply- managed agriculture sectors such as dairy and poultry Taxation data for annual disaggregated financial information Cost-recovery program (e.g. farm assets and liabilities, etc.) Farm Register Agriculture surveys’ frame Large, complex agricultural operations’ profile Joint collection agreements with most provincial and territorial departments of agriculture

17 Agriculture Statistics Framework

18 Agriculture Program Metadata IMDB includes 45 separate records covering current survey activities One step further: the statistical activity IMDB structure that groups together surveys that share common processing system or conceptual framework Agriculture statistics program statistical activity would be organized around the farm income series structure would facilitate users’ understanding of the interrelationships between the various components of the integrated program Would increase users’ awareness that the “fitness for use” test of the farm income series should take into account the metadata information of all the farm income series’ inputs.

19 Conclusion Data quality is a survival issue for any statistical agency loss of users’ confidence in data would render statistical agency ineffective Metadata: openness and transparency about data –about their weaknesses just as much as about their strengths IMDB – by making metadata easily accessible to users – helps build trust
