- Articles and reports: 12-001-X202300200013Description: Jean-Claude Deville is one of the most prominent researcher in survey sampling theory and practice. His research on balanced sampling, indirect sampling and calibration in particular is internationally recognized and widely used in official statistics. He was also a pioneer in the field of functional data analysis. This discussion gives us the opportunity to recognize the immense work he has accomplished, and to pay tribute to him. In the first part of this article, we recall briefly his contribution to the functional principal analysis. We also detail some recent extension of his work at the intersection of the fields of functional data analysis and survey sampling. In the second part of this paper, we present some extension of Jean-Claude’s work in indirect sampling. These extensions are motivated by concrete applications and illustrate Jean-Claude’s influence on our work as researchers.Release date: 2024-01-03

- Articles and reports: 12-001-X202300100007Description: I provide an overview of the evolution of Statistical Disclosure Control (SDC) research over the last decades and how it has evolved to handle the data revolution with more formal definitions of privacy. I emphasize the many contributions by Chris Skinner in the research areas of SDC. I review his seminal research, starting in the 1990’s with his work on the release of UK Census sample microdata. This led to a wide-range of research on measuring the risk of re-identification in survey microdata through probabilistic models. I also focus on other aspects of Chris’ research in SDC. Chris was the recipient of the 2019 Waksberg Award and sadly never got a chance to present his Waksberg Lecture at the Statistics Canada International Methodology Symposium. This paper follows the outline that Chris had prepared in preparation for that lecture.Release date: 2023-06-30

For several decades, national statistical agencies around the world have been using probability surveys as their preferred tool to meet information needs about a population of interest. In the last few years, there has been a wind of change and other data sources are being increasingly explored. Five key factors are behind this trend: the decline in response rates in probability surveys, the high cost of data collection, the increased burden on respondents, the desire for access to “real-time” statistics, and the proliferation of non-probability data sources. Some people have even come to believe that probability surveys could gradually disappear. In this article, we review some approaches that can reduce, or even eliminate, the use of probability surveys, all the while preserving a valid statistical inference framework. All the approaches we consider use data from a non-probability source; data from a probability survey are also used in most cases. Some of these approaches rely on the validity of model assumptions, which contrasts with approaches based on the probability sampling design. These design-based approaches are generally not as efficient; yet, they are not subject to the risk of bias due to model misspecification.

Historical works allow readers to peer into the past, not only to satisfy our curiosity about “the way things were,” but also to see how far we’ve come, and to learn from the past. For Statistics Canada, such works are also opportunities to commemorate the agency’s contributions to Canada and its people, and serve as a reminder that an institution such as this continues to evolve each and every day.
On the occasion of Statistics Canada’s 100th anniversary in 2018, Standing on the shoulders of giants: History of Statistics Canada: 1970 to 2008, builds on the work of two significant publications on the history of the agency, picking up the story in 1970 and carrying it through the next 36 years, until 2008. To that end, when enough time has passed to allow for sufficient objectivity, it will again be time to document the agency’s next chapter as it continues to tell Canada’s story in numbers.

Release date: 2002-06-28 - 9. Purchasing Power Parities and Real Expenditures, United States and Canada - An Update to 1998 ArchivedStats in brief: 13-604-M1999036Description:
Recent economic trends, including expanding globalization of trade (as evidenced by new trade agreements), volatility in market exchange rates, and greater interest in international comparisons of real income and productivity are generating increased interest in intercountry comparisons. These comparisons are made in real terms derived from purchasing power parities (PPPs). In Canada, a particularly important relationship with the United States focusses attention on US/Canada comparative price and volume measures. This article includes updated annual bilateral volume indexes of real gross domestic product (GDP) per capita and its components for the United States, compared with Canada, and the associated PPPs.

Release date: 2003-01-29 - 42. Leslie Kish's impact on survey statistics ArchivedArticles and reports: 12-001-X200200113019Description: This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.
Leslie Kish, one of the pioneers of survey sampling, died on October 7, 2000, at the age of 90. This paper reviews how he has influenced survey statistics, mainly in terms of his research, but also in terms of his world-wide promotion of sound probability sampling methods. Kish's research had a broad range, covering sampling methods; non-sampling errors; small area estimation; observational studies; variance estimation and design effects; and survey designs across time and space. He promoted probability sampling designs through his writings, international consultancies , and in particular, through the highly effective, intensive summer Sampling Program for Foreign Statisticians that he established at the Survey Research Center of the University of Michigan.

Mahalanobis provided an example of how to use statistics to enlighten and inform government policy makers. His pioneering work was used by the US Bureau of the Census to learn more about measurement errors in censuses and surveys. People have many misconceptions about censuses, among them who is to be counted and where. Errors in the census do occur, among them errors in coverage. Over the years, the US Bureau of the Census has developed statistical techniques, including sampling in the census, to increase accuracy and reduce response burden.

Release date: 2000-03-01 - 47. Core Inflation: A Weighted Median Index ArchivedArticles and reports: 62F0014M1998007Geography: CanadaDescription:
Over the years, the concept of core inflation has become of crucial importance for the central banks of various countries. Indeed, many of them have at some point given themselves the mandate to reduce inflation and achieve price stability. The Bank of Canada undertook this mandate in February 1991.
Core inflation should reflect what is basic in price movements and ignore temporary fluctuations that have no long-term impact on prices. The phenomenon of core inflation must be of a lasting nature. The targets were initially set on the basis of the overall consumer price index (CPI). However, the Bank of Canada has stated that for practical reasons, it will focus on the consumer price index excluding the volatile food and energy components.
The question that many are asking is the following: is a measure such as the CPI excluding food and energy a good indicator of core inflation? At the meeting of the 1996 Price Measurement Advisory Committee, a review of the literature on core inflation was presented. The Committee recommended taking a closer look at a weighted median index as a means of estimating core inflation. This study deals with the question of a weighted median index and covers the period of January 1985 to January 1997. The rates of change in the weighted median index calculated from monthly movements are quite often lower than the rates of change in the official index. This behaviour reflects the usual distribution of monthly price movements for the CPI, meaning a large proportion of the monthly movements are close to zero, and the remaining price movements are, in majority, positive. Because of this behaviour of monthly movements, the weighted median index advances much more slowly than the official index. This behaviour is just as evident when inflation advances at annual rates of 4% to 5% as when it ranges around 2%. An index based on the weighted median of monthly movements in the CPI yields somewhat disconcerting results. Even though some think that the official CPI does not clearly reflect the concept of core inflation, one does not necessarily expect to see such a large gap develop over time.

We review the current status of various aspects of the design and analysis of studies where the same units are investigated at several points in time. These studies include longitudinal surveys, and longitudinal analyses of retrospective studies and of administrative or census data. The major focus is the special problems posed by the longitudinal nature of the study. We discuss four of the major components of longitudinal studies in general; namely, Design, Implementation, Evaluation and Analysis. Each of these components requires special considerations when planning a longitudinal study. Some issues relating to the longitudinal nature of the studies are: concepts and definitions, frames, sampling, data collection, nonresponse treatment, imputation, estimation, data validation, data analysis and dissemination. Assuming familiarity with the basic requirements for conducting a cross-sectional survey, we highlight the issues and problems that become apparent for many longitudinal studies.
Release date: 1999-01-14 - 49. Review of the Literature on Core Inflation ArchivedArticles and reports: 62F0014M1997004Geography: CanadaDescription:
Over the years, the concept of core inflation has become of crucial importance for the central banks of various countries. Indeed, many of them have at some point been given the mandate to reduce inflation and achieve price stability. In Canada, this mandate was conferred on the Bank of Canada in February 1991.
Core Inflation is often perceived as the trend in the movements of consumer prices. This review of the literature illustrates that more than one definition of core inflation exists. Then, a brief description of the different suggested methods to measure core inflation, as well as some of their results, are shown. Finally, this review offers a bibliography of articles on core inflation.

Stanley Warner was widely known for the creation of the randomized response technique for asking sensitive questions in surveys. Over almost two decades he also formulated and developed statistical methodology for another problem, that of deriving balanced information in advocacy settings so that both positions regarding a policy issue can be fairly and adequately represented. We review this work, including two survey applications implemented by Warner in which he applied the methodology, and we set the ideas into the context of current methodological thinking.
