    Description:

    At the Institut national de santé publique du Québec, the Quebec Integrated Chronic Disease Surveillance System (QICDSS) has been used daily for approximately four years. The benefits of this system are numerous for measuring the extent of diseases more accurately, evaluating the use of health services properly and identifying certain groups at risk. However, in the past months, various problems have arisen that have required a great deal of careful thought. The problems have affected various areas of activity, such as data linkage, data quality, coordinating multiple users and meeting legal obligations. The purpose of this presentation is to describe the main challenges associated with using QICDSS data and to present some possible solutions. In particular, this presentation discusses the processing of five data sources that not only come from five different sources, but also are not mainly used for chronic disease surveillance. The varying quality of the data, both across files and within a given file, will also be discussed. Certain situations associated with the simultaneous use of the system by multiple users will also be examined. Examples will be given of analyses of large data sets that have caused problems. As well, a few challenges involving disclosure and the fulfillment of legal agreements will be briefly discussed.

    Description:

    This paper is intended to give a brief overview of Statistics Canada’s involvement with open data. It will first discuss how the principles of open data are being adopted in the agency’s ongoing dissemination practices. It will then discuss the agency’s involvement with the whole of government open data initiative. This involvement is twofold: Statistics Canada is the major data contributor to the Government of Canada Open Data portal, but also plays an important behind the scenes role as the service provider responsible for developing and maintaining the Open Data portal (which is now part of the wider Open Government portal.)

    Description:

    This paper describes the Quick Match System (QMS), an in-house application designed to match business microdata records, and the methods used to link the United States Patent and Trademark Office (USPTO) dataset to Statistics Canada’s Business Register (BR) for the period from 2000 to 2011. The paper illustrates the record-linkage framework and outlines the techniques used to prepare and classify each record and evaluate the match results. The USPTO dataset consisted of 41,619 U.S. patents granted to 14,162 distinct Canadian entities. The record-linkage process matched the names, city, province and postal codes of the patent assignees in the USPTO dataset with those of businesses in the January editions of the Generic Survey Universe File (GSUF) from the BR for the same reference period. As the vast majority of individual patent assignees are not engaged in commercial activity to provide taxable property or services, they tend not to appear in the BR. The relatively poor match rate of 24.5% among individuals, compared to 84.7% among institutions, reflects this tendency. Although the 8,844 individual patent assignees outnumbered the 5,318 institutions, the institutions accounted for 73.0% of the patents, compared to 27.0% held by individuals. Consequently, this study and its conclusions focus primarily on institutional patent assignees. The linkage of the USPTO institutions to the BR is significant because it provides access to business micro-level data on firm characteristics, employment, revenue, assets and liabilities. In addition, the retrieval of robust administrative identifiers enables subsequent linkage to other survey and administrative data sources. The integrated dataset will support direct and comparative analytical studies on the performance of Canadian institutions that obtained patents in the United States between 2000 and 2011.

    Description:

    "This presentation will begin with Dr. West providing a summary of research that has been conducted on the quality and utility of paradata collected as part of the United States National Survey of Family Growth (NSFG). The NSFG is the major national fertility survey in the U.S., and an important source of data on sexual activity, sexual behavior, and reproductive health for policy makers. For many years, the NSFG has been collecting various forms of paradata, including keystroke information (e.g., Couper and Kreuter 2013), call record information, detailed case disposition information, and interviewer observations related to key NSFG measures (e.g., West 2013). Dr. West will discuss some of the challenges of working with these data, in addition to evidence of their utility for nonresponse adjustment, interviewer evaluation, and/or responsive survey design purposes. Dr. Kreuter will then present research done using paradata collected as part of two panel surveys: the Medical Expenditure Panel Survey (MEPS) in the United States, and the Panel Labour Market and Social Security (PASS) in Germany. In both surveys, information from contacts in prior waves were experimentally used to improve contact and response rates in subsequent waves. In addition, research from PASS will be presented where interviewer observations on key outcome variables were collected to be used in nonresponse adjustment or responsive survey design decisions. Dr. Kreuter will not only present the research results but also the practical challenges in implementing the collection and use of both sets of paradata. "

    Description:

    In the standard design approach to missing observations, the construction of weight classes and calibration are used to adjust the design weights for the respondents in the sample. Here we use these adjusted weights to define a Dirichlet distribution which can be used to make inferences about the population. Examples show that the resulting procedures have better performance properties than the standard methods when the population is skewed.

    Description:

    Background: There is increasing interest in measuring and benchmarking health system performance. We compared Canada’s health system with other countries in the Organisation for Economic Co-operation and Development (OECD) on both the national and provincial levels, across 50 indicators of health system performance. This analysis can help provinces identify potential areas for improvement, considering an optimal comparator for international comparisons. Methods: OECD Health Data from 2013 was used to compare Canada’s results internationally. We also calculated provincial results for OECD’s indicators on health system performance, using OECD methodology. We normalized the indicator results to present multiple indicators on the same scale and compared them to the OECD average, 25th and 75th percentiles. Results: Presenting normalized values allow Canada’s results to be compared across multiple OECD indicators on the same scale. No country or province consistently has higher results than the others. For most indicators, Canadian results are similar to other countries, but there remain areas where Canada performs particularly well (i.e. smoking rates) or poorly (i.e. patient safety). This data was presented in an interactive eTool. Conclusion: Comparing Canada’s provinces internationally can highlight areas where improvement is needed, and help to identify potential strategies for improvement.

    Description:

    The U.S. Census Bureau is researching uses of administrative records in survey and decennial operations in order to reduce costs and respondent burden while preserving data quality. One potential use of administrative records is to utilize the data when race and Hispanic origin responses are missing. When federal and third party administrative records are compiled, race and Hispanic origin responses are not always the same for an individual across different administrative records sources. We explore different sets of business rules used to assign one race and one Hispanic response when these responses are discrepant across sources. We also describe the characteristics of individuals with matching, non-matching, and missing race and Hispanic origin data across several demographic, household, and contextual variables. We find that minorities, especially Hispanics, are more likely to have non-matching Hispanic origin and race responses in administrative records than in the 2010 Census. Hispanics are less likely to have missing Hispanic origin data but more likely to have missing race data in administrative records. Non-Hispanic Asians and non-Hispanic Pacific Islanders are more likely to have missing race and Hispanic origin data in administrative records. Younger individuals, renters, individuals living in households with two or more people, individuals who responded to the census in the nonresponse follow-up operation, and individuals residing in urban areas are more likely to have non-matching race and Hispanic origin responses.

    Over the last decade, Statistics Canada’s Producer Prices Division has expanded its service producer price indexes program and continued to improve its goods and construction producer price indexes program. While the majority of price indexes are based on traditional survey methods, efforts were made to increase the use of administrative data and alternative data sources in order to reduce burden on our respondents. This paper focuses mainly on producer price programs, but also provides information on the growing importance of alternative data sources at Statistics Canada. In addition, it presents the operational challenges and risks that statistical offices could face when relying more and more on third-party outputs. Finally, it presents the tools being developed to integrate alternative data while collecting metadata.

    Description:

    Statistics Canada’s mandate includes producing statistical data to shed light on current business issues. The linking of business records is an important aspect of the development, production, evaluation and analysis of these statistical data. As record linkage can intrude on one’s privacy, Statistics Canada uses it only when the public good is clear and outweighs the intrusion. Record linkage is experiencing a revival triggered by a greater use of administrative data in many statistical programs. There are many challenges to business record linkage. For example, many administrative files not have common identifiers, information is recorded is in non-standardized formats, information contains typographical errors, administrative data files are usually large in size, and finally the evaluation of multiple record pairings makes absolute comparison impractical and sometimes impossible. Due to the importance and challenges associated with record linkage, Statistics Canada has been developing a record linkage standard to help users optimize their business record linkage process. For example, this process includes building on a record linkage blocking strategy that reduces the amount of record-pairs to compare and match, making use of Statistics Canada’s internal software to conduct deterministic and probabilistic matching, and creating standard business name and address fields on Statistics Canada’s Business Register. This article gives an overview of the business record linkage methodology and looks at various economic projects which use record linkage at Statistics Canada, these include projects in the National Accounts, International Trade, Agriculture and the Business Register.

    Description:

    How can we bring together multidimensional health system performance data in a simplified way that is easy to access and provides comparable and actionable information to accelerate improvements in health care? The Canadian Institute for Health Information has developed a suite of tools to meet performance measurement needs across different audiences, to identify improvement priorities, understand how health regions and facilities compare with peers and support transparency and accountability. The pan-Canadian tools [Your Health System (YHS)] consolidates reporting of 45 key performance indicators in a structured way, and are comparable over time and at different geographic levels. This paper outlines the development and the methodological approaches and considerations taken to create a dynamic tool that facilitates benchmarking and meaningful comparisons for health system performance improvement.

    Tax data are being used more and more to measure and analyze the population and its characteristics. One of the issues raised by the growing use of these type of data relates to the definition of the concept of place of residence. While the census uses the traditional concept of place of residence, tax data provide information based on the mailing address of tax filers. Using record linkage between the census, the National Household Survey and tax data from the T1 Family File, this study examines the consistency level of the place of residence of these two sources and its associated characteristics.

    Description:

    The Absence from Work Survey was designed primarily to fulfill the objectives of Human Resources Development Canada. They sponsor the qualified wage loss replacement plan which applies to employers who have their own private plans to cover employee wages lost due to sickness, accident, etc. Employers who fall under the plan are granted a reduction in their quotas payable to the Unemployment Insurance Commission. The data generated from the responses to the supplement will provide input to determine the rates for quota reductions for qualified employers.

    Although the Absence from Work Survey collects information on absences from work due to illness, accident or pregnancy, it does not provide a complete picture of people who have been absent from work for these reasons because the concepts and definitions have been developed specifically for the needs of the client. Absences in this survey are defined as being at least two weeks in length, and respondents are only asked the three reasons for their most recent absence and the one preceding it.

    Description:

    Since 2008, a number of population censuses have been linked to administrative health data and to financial data. These linked datasets have been instrumental in examining health inequalities and have been used in environmental health research. This paper describes the creation of the 1996 Canadian Census Health and Environment Cohort (CanCHEC)—3.57 million respondents to the census long-form questionnaire who were retrospectively followed for mortality and mobility for 16.6 years from 1996 to 2012. The 1996 CanCHEC was limited to census respondents who were aged 19 or older on Census Day (May 14, 1996), were residents of Canada, were not residents of institutions, and had filed an income tax return. These respondents were linked to death records from the Canadian Mortality Database or to the T1 Personal Master File, and to a postal code history from a variety of sources. This is the third in a set of CanCHECs that, when combined, make it possible to examine mortality trends and environmental exposures by socioeconomic characteristics over three census cycles and 21 years of census, tax, and mortality data. This report describes linkage methodologies, validation and bias assessment, and the characteristics of the 1996 CanCHEC. Representativeness of the 1996 CanCHEC relative to the adult population of Canada is also assessed.

    The Longitudinal Immigration Database (IMDB) is a comprehensive source of data that plays a key role in the understanding of the economic behaviour of immigrants. It is the only annual Canadian dataset that allows users to study the characteristics of immigrants to Canada at the time of admission and their economic outcomes and regional (inter-provincial) mobility over a time span of more than 30 years. The IMDB combines administrative files on immigrant admissions and non-permanent resident permits from Immigration, Refugees and Citizenship Canada (IRCC) with tax files from the Canadian Revenue Agency (CRA). Information is available for immigrant taxfilers admitted since 1980. Tax records for 1982 and subsequent years are available for immigrant taxfilers.

    This report will discuss the IMDB data sources, concepts and variables, record linkage, data processing, dissemination, data evaluation and quality indicators, comparability with other immigration datasets, and the analyses possible with the IMDB.

    Description:

    In this paper the question is addressed how alternative data sources, such as administrative and social media data, can be used in the production of official statistics. Since most surveys at national statistical institutes are conducted repeatedly over time, a multivariate structural time series modelling approach is proposed to model the series observed by a repeated surveys with related series obtained from such alternative data sources. Generally, this improves the precision of the direct survey estimates by using sample information observed in preceding periods and information from related auxiliary series. This model also makes it possible to utilize the higher frequency of the social media to produce more precise estimates for the sample survey in real time at the moment that statistics for the social media become available but the sample data are not yet available. The concept of cointegration is applied to address the question to which extent the alternative series represent the same phenomena as the series observed with the repeated survey. The methodology is applied to the Dutch Consumer Confidence Survey and a sentiment index derived from social media.

    Description:

    This note discusses the theoretical foundations for the extension of the Wilson two-sided coverage interval to an estimated proportion computed from complex survey data. The interval is shown to be asymptotically equivalent to an interval derived from a logistic transformation. A mildly better version is discussed, but users may prefer constructing a one-sided interval already in the literature.

    Description:

    We discuss developments in sample survey theory and methods covering the past 100 years. Neyman’s 1934 landmark paper laid the theoretical foundations for the probability sampling approach to inference from survey samples. Classical sampling books by Cochran, Deming, Hansen, Hurwitz and Madow, Sukhatme, and Yates, which appeared in the early 1950s, expanded and elaborated the theory of probability sampling, emphasizing unbiasedness, model free features, and designs that minimize variance for a fixed cost. During the period 1960-1970, theoretical foundations of inference from survey data received attention, with the model-dependent approach generating considerable discussion. Introduction of general purpose statistical software led to the use of such software with survey data, which led to the design of methods specifically for complex survey data. At the same time, weighting methods, such as regression estimation and calibration, became practical and design consistency replaced unbiasedness as the requirement for standard estimators. A bit later, computer-intensive resampling methods also became practical for large scale survey samples. Improved computer power led to more sophisticated imputation for missing data, use of more auxiliary data, some treatment of measurement errors in estimation, and more complex estimation procedures. A notable use of models was in the expanded use of small area estimation. Future directions in research and methods will be influenced by budgets, response rates, timeliness, improved data collection devices, and availability of auxiliary data, some of which will come from “Big Data”. Survey taking will be impacted by changing cultural behavior and by a changing physical-technical environment.

    Description:

    This paper proposes a new approach to decompose the wage difference between men and women that is based on a calibration procedure. This approach generalizes two current decomposition methods that are re-expressed using survey weights. The first one is the Blinder-Oaxaca method and the second one is a reweighting method proposed by DiNardo, Fortin and Lemieux. The new approach provides a weighting system that enables us to estimate such parameters of interest like quantiles. An application to data from the Swiss Structure of Earnings Survey shows the interest of this method.

    On April 13, 2017, the Government of Canada tabled legislation to legalize the recreational use of cannabis by adults. This will directly impact Canada’s statistical system. The focus of this Economic Insights article is to provide experimental estimates for the volume of cannabis consumption, based on existing information on the prevalence of cannabis use. The article presents experimental estimates of the number of tonnes of cannabis consumed by age group for the period from 1960 to 2015. The experimental estimates rely on survey data from multiple sources, statistical techniques to link the sources over time, and assumptions about consumption behaviour. They are subject to revision as improved or additional data sources become available.

    Description:

    Canada is a trading nation that produces significant quantities of resource outputs. Consequently, the behaviour of resource prices that are important for Canada is germane to understanding the progress of real income growth and the prosperity of the country and the provinces. Demand and supply shocks or changes in monetary policy in international markets may exert significant influence on resource prices, and their fluctuations constitute an important avenue for the transmission of external shocks into the domestic economy. This paper develops historical estimates of the Bank of Canada commodity price index (BCPI) and links them to modern estimates. Using a collection of historical data sources, it estimates weights and prices sufficiently consistently to merit the construction of long-run estimates that may be linked to the modern Fisher BCPI.

    Description:

    Statistics Canada is presently preparing the statistical system to be able to gauge the impact of the transition from illegal to legal non-medical cannabis use and to shed light on the social and economic activities related to the use of cannabis thereafter. While the system of social statistics captures some information on the use of cannabis, updates will be required to more accurately measure health effects and the impact on the judicial system. Current statistical infrastructure used to more comprehensively measure the use and impacts of substances such as tobacco and alcohol could be adapted to do the same for cannabis. However, available economic statistics are largely silent on the role illegal drugs play in the economy. Both social and economic statistics will need to be updated to reflect the legalization of cannabis and the challenge is especially great for economic statistics This paper provides a summary of the work that is now under way toward these ends.

    This study assessed whether starting participation in Employment Assistance Services (EAS) earlier after initiating an Employment Insurance (EI) claim leads to better impacts for unemployed individuals than participating later during the EI benefit period. As in Sianesi (2004) and Hujer and Thomsen (2010), the analysis relied on a stratified propensity score matching approach conditional on the discretized duration of unemployment until the program starts. The results showed that individuals who participated in EAS within the first four weeks after initiating an EI claim had the best impacts on earnings and incidence of employment while also experiencing reduced use of EI starting the second year post-program.

    Description:

    The Educational Master File (EMF) system was built to allow the analysis of educational programs in Canada. At the core of the system are administrative files that record all of the registrations to post-secondary and apprenticeship programs in Canada. New administrative files become available on an annual basis. Once a new file becomes available, a first round of processing is performed, which includes linkage to other administrative records. This linkage yields information that can improve the quality of the file, it allows further linkages to other data describing labour market outcomes, and it’s the first step in adding the file to the EMF. Once part of the EMF, information from the file can be included in cross-sectional and longitudinal projects, to study academic pathways and labour market outcomes after graduation. The EMF currently consists of data from 2005 to 2013, but it evolves as new data become available. This paper gives an overview of the mechanisms used to build the EMF, with focus on the structure of the final system and some of its analytical potential.

    Description:

    "Probability samples of near-universal frames of households and persons, administered standardized measures, yielding long multivariate data records, and analyzed with statistical procedures reflecting the design – these have been the cornerstones of the empirical social sciences for 75 years. That measurement structure have given the developed world almost all of what we know about our societies and their economies. The stored survey data form a unique historical record. We live now in a different data world than that in which the leadership of statistical agencies and the social sciences were raised. High-dimensional data are ubiquitously being produced from Internet search activities, mobile Internet devices, social media, sensors, retail store scanners, and other devices. Some estimate that these data sources are increasing in size at the rate of 40% per year. Together their sizes swamp that of the probability-based sample surveys. Further, the state of sample surveys in the developed world is not healthy. Falling rates of survey participation are linked with ever-inflated costs of data collection. Despite growing needs for information, the creation of new survey vehicles is hampered by strained budgets for official statistical agencies and social science funders. These combined observations are unprecedented challenges for the basic paradigm of inference in the social and economic sciences. This paper discusses alternative ways forward at this moment in history. "

    Description:

    Data protection and privacy are key challenges that need to be tackled with high priority in order to enable the use of Big Data in the production of Official Statistics. This was emphasized in 2013 by the Directors of National Statistical Insitutes (NSIs) of the European Statistical System Committee (ESSC) in the Scheveningen Memorandum. The ESSC requested Eurostat and the NSIs to elaborate an action plan with a roadmap for following up the implementation of the Memorandum. At the Riga meeting on September 26, 2014, the ESSC endorsed the Big Data Action Plan and Roadmap 1.0 (BDAR) presented by the Eurostat Task Force on Big Data (TFBD) and agreed to integrate it into the ESS Vision 2020 portfolio. Eurostat also collaborates in this field with external partners such as the United Nations Economic Commission for Europe (UNECE). The big data project of the UNECE High-Level Group is an international project on the role of big data in the modernization of statistical production. It comprised four ‘task teams’ addressing different aspects of Big Data issues relevant for official statistics: Privacy, Partnerships, Sandbox, and Quality. The Privacy Task Team finished its work in 2014 and gave an overview of the existing tools for risk management regarding privacy issues, described how risk of identification relates to Big Data characteristics and drafted recommendations for National Statistical Offices (NSOs). It mainly concluded that extensions to existing frameworks, including use of new technologies were needed in order to deal with privacy risks related to the use of Big Data. The BDAR builds on the work achieved by the UNECE task teams. Specifically, it recognizes that a number of big data sources contain sensitive information, that their use for official statistics may induce negative perceptions with the general public and other stakeholders and that this risk should be mitigated in the short to medium term. It proposes to launch multiple actions like e.g., an adequate review on ethical principles governing the roles and activities of the NSIs and a strong communication strategy. The paper presents the different actions undertaken within the ESS and in collaboration with UNECE, as well as potential technical and legal solutions to be put in place in order to address the data protection and privacy risks in the use of Big Data for Official Statistics.

    Description:

    The Longitudinal Immigration Database (IMDB) combines the Immigrant Landing File (ILF) with annual tax files. This record linkage is performed using a tax filer database. The ILF includes all immigrants who have landed in Canada since 1980. In looking to enhance the IMDB, the possibility of adding temporary residents (TR) and immigrants who landed between 1952 and 1979 (PRE80) was studied. Adding this information would give a more complete picture of the immigrant population living in Canada. To integrate the TR and PRE80 files into the IMDB, record linkages between these two files and the tax filer database, were performed. This exercise was challenging in part due to the presence of duplicates in the files and conflicting links between the different record linkages.

    After the 2010 Census, the U.S. Census Bureau conducted two separate research projects matching survey data to databases. One study matched to the third-party database Accurint, and the other matched to U.S. Postal Service National Change of Address (NCOA) files. In both projects, we evaluated response error in reported move dates by comparing the self-reported move date to records in the database. We encountered similar challenges in the two projects. This paper discusses our experience using “big data” as a comparison source for survey data and our lessons learned for future projects similar to the ones we conducted.

Access and visualization of such data is done through a limited number of customized tables and simple diagrams, which do not entirely meet the needs of health managers and other users for a flexible and easy-to-use tool that can tackle different aspects of health which are relevant to their purposes of knowledge-seeking and decision-making. We propose the interactive monthly generation of synthetic epidemiological reports, which are not only easily accessible but also easy to interpret and understand. Emphasis is put on data visualization through more informative diagrams and maps.

    Our study describes various factors that are of concern when evaluating disclosure risk of contextualized microdata and some of the empirical steps that are involved in their assessment. Utilizing synthetic sets of survey respondents, we illustrate how different postulates shape the assessment of risk when considering: (1) estimated probabilities that unidentified geographic areas are represented within a survey; (2) the number of people in the population who share the same personal and contextual identifiers as a respondent; and (3) the anticipated amount of coverage error in census population counts and extant files that provide identifying information (like names and addresses).

    Description:

    In the design of surveys a number of parameters like contact propensities, participation propensities and costs per sample unit play a decisive role. In on-going surveys, these survey design parameters are usually estimated from previous experience and updated gradually with new experience. In new surveys, these parameters are estimated from expert opinion and experience with similar surveys. Although survey institutes have a fair expertise and experience, the postulation, estimation and updating of survey design parameters is rarely done in a systematic way. This paper presents a Bayesian framework to include and update prior knowledge and expert opinion about the parameters. This framework is set in the context of adaptive survey designs in which different population units may receive different treatment given quality and cost objectives. For this type of survey, the accuracy of design parameters becomes even more crucial to effective design decisions. The framework allows for a Bayesian analysis of the performance of a survey during data collection and in between waves of a survey. We demonstrate the Bayesian analysis using a realistic simulation study.

    Description:

    The U.S. Census Bureau is researching ways to incorporate administrative data in decennial census and survey operations. Critical to this work is an understanding of the coverage of the population by administrative records. Using federal and third party administrative data linked to the American Community Survey (ACS), we evaluate the extent to which administrative records provide data on foreign-born individuals in the ACS and employ multinomial logistic regression techniques to evaluate characteristics of those who are in administrative records relative to those who are not. We find that overall, administrative records provide high coverage of foreign-born individuals in our sample for whom a match can be determined. The odds of being in administrative records are found to be tied to the processes of immigrant assimilation – naturalization, higher English proficiency, educational attainment, and full-time employment are associated with greater odds of being in administrative records. These findings suggest that as immigrants adapt and integrate into U.S. society, they are more likely to be involved in government and commercial processes and programs for which we are including data. We further explore administrative records coverage for the two largest race/ethnic groups in our sample – Hispanic and non-Hispanic single-race Asian foreign born, finding again that characteristics related to assimilation are associated with administrative records coverage for both groups. However, we observe that neighborhood context impacts Hispanics and Asians differently.

    Description:

    Microdata dissemination normally requires data reduction and modification methods be applied, and the degree to which these methods are applied depend on the control methods that will be required to access and use the data. An approach that is in some circumstances more suitable for accessing data for statistical purposes is secure computation, which involves computing analytic functions on encrypted data without the need to decrypt the underlying source data to run a statistical analysis. This approach also allows multiple sites to contribute data while providing strong privacy guarantees. This way the data can be pooled and contributors can compute analytic functions without either party knowing their inputs. We explain how secure computation can be applied in practical contexts, with some theoretical results and real healthcare examples.

    Description:

    Practically all major retailers use scanners to record the information on their transactions with clients (consumers). These data normally include the product code, a brief description, the price and the quantity sold. This is an extremely relevant data source for statistical programs such as Statistics Canada’s Consumer Price Index (CPI), one of Canada’s most important economic indicators. Using scanner data could improve the quality of the CPI by increasing the number of prices used in calculations, expanding geographic coverage and including the quantities sold, among other things, while lowering data collection costs. However, using these data presents many challenges. An examination of scanner data from a first retailer revealed a high rate of change in product identification codes over a one-year period. The effects of these changes pose challenges from a product classification and estimate quality perspective. This article focuses on the issues associated with acquiring, classifying and examining these data to assess their quality for use in the CPI.

    Administrative data, depending on its source and original purpose, can be considered a more reliable source of information than survey-collected data. It does not require a respondent to be present and understand question wording, and it is not limited by the respondent’s ability to recall events retrospectively. This paper compares selected survey data, such as demographic variables, from the Longitudinal and International Study of Adults (LISA) to various administrative sources for which LISA has linkage agreements in place. The agreement between data sources, and some factors that might affect it, are analyzed for various aspects of the survey.
