- Articles and reports: 12-001-X202300200012Description: In recent decades, many different uses of auxiliary information have enriched survey sampling theory and practice. Jean-Claude Deville contributed significantly to this progress. My comments trace some of the steps on the way to one important theory for the use of auxiliary information: Estimation by calibration.Release date: 2024-01-03
- 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.

The Participation and Activity Limitation Survey (PALS) is Canada's national survey that gathers information about adults and children whose daily activities are limited by a physical, mental, or other health-related condition or problem.
This report presents some basic information about the survey and an overview of the methodological and content changes between the 2001 and 2006 PALS. The major difference involves a change in coverage resulting from the inclusion of a number of aboriginal communities, the addition of the three territories, and the modification to the definition of collective dwellings.

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.

- 21. Low-income Dynamics and Determinants Under Different Thresholds: New Findings for Canada in 2000 and Beyond ArchivedArticles and reports: 75F0002M2011003Description:
Existing studies on Canadian poverty (or low-income) dynamics are mainly based on 1990s data from the Longitudinal Administrative Database or the Survey of Labour and Income Dynamics (SLID). These studies typically rely on a single low-income threshold.
Our work extends the existing studies beyond 1999 by using SLID data from Panel 3 (1999 to 2004) and Panel 4 (2002 to 2007). We consider all three low-income thresholds established by federal departments: Statistics Canada's low-income cut-off (LICO) and low-income measure (LIM), and the market basket measure (MBM) of Human Resources and Skills Development Canada.
Release date: 2011-10-21 - 22. Low Income Lines, 2009-2010 ArchivedArticles and reports: 75F0002M2011002Description:
In order to provide a holographic or complete picture of low income, Statistics Canada uses three complementary low income lines: the Low Income Cut-offs (LICOs), the Low Income Measures (LIMs) and the Market Basket Measure (MBM). While the first two lines were developed by Statistics Canada, the MBM is based on concepts developed by Human Resources and Skill Development Canada. Though these measures differ from one another, they give a generally consistent picture of low income status over time. None of these measures is the best. Each contributes its own perspective and its own strengths to the study of low income, so that cumulatively, the three provide a better understanding of the phenomenon of low income as a whole. These measures are not measures of poverty, but strictly measures of low income.
Release date: 2011-06-15 - 23. The organisation of statistical methodology and methodological research in national statistical offices ArchivedArticles and reports: 12-001-X201000211375Description:
The paper explores and assesses the approaches used by statistical offices to ensure effective methodological input into their statistical practice. The tension between independence and relevance is a common theme: generally, methodologists have to work closely with the rest of the statistical organisation for their work to be relevant; but they also need to have a degree of independence to question the use of existing methods and to lead the introduction of new ones where needed. And, of course, there is a need for an effective research program which, on the one hand, has a degree of independence needed by any research program, but which, on the other hand, is sufficiently connected so that its work is both motivated by and feeds back into the daily work of the statistical office. The paper explores alternative modalities of organisation; leadership; planning and funding; the role of project teams; career development; external advisory committees; interaction with the academic community; and research.

Release date: 2010-06-17 - Articles and reports: 75F0002M2010003Description:
This study assesses the existing LICO, LIM, and MBM lines, together with a fixed LIM, by using several distribution sensitive indexes. We found that the low income lines tracked each other well in the long-run. But, in the short-run, they often behaved differently. The same was observed when examining different indexes under the same line. In the long-run, the low income rate, gap, and severity indexes all moved in the same direction. However in the short-run, they sometimes varied in opposite directions, or in the same direction with different magnitudes, suggesting that a single line or index can be misleading in some circumstances.

Regression estimation has only been used extensively by statistical organizations in recent years. The sample mean and the classical ratio estimator are particular cases of this estimator. Both have a long history that can be traced back to the ancient Greeks or earlier. For instance, the ratio estimator was used by the Egyptians and Babylonians to compute the circumference of a circle given its radius, given a constant approximating the famous pi value. Multiple examples that use the ratio estimator as a means to indirectly compute a measure of interest can be found in physics, and engineering. The ratio estimator was also used to estimate population census estimates in the past when exact counts were beyond the capabilities of the existing administrations (for example John Graunt 1662, and Laplace late eighteenth century).
In this talk, we will trace the evolution of the regression estimation in survey sampling from the 1930's to the present time. We will outline its advantages and disadvantages in using it in survey sampling. Corresponding software development will also be presented

On October 31 and November 1, 2007, Statistics Canada held a special methodology conference in honour of Professor Carl-Erik Särndal entitled Workshop on Calibration and Estimation in Surveys (WCES). The workshop focused on diverse aspects of Professor Särndal's career - his work, teachings and writings having had a profound affect on the way methodologists carry out their daily duties, both here and abroad. He was a consultant to Statistics Canada for many years and is a member of the Advisory Committee on Statistical Methods. Professor Särndal's deep and lasting influence in this field earned him the 2007 Waksberg Award, one of the most prestigious honours a statistician can receive in recognition of his or her work in survey sampling statistics.

The National Health and Nutrition Examination Survey (NHANES) has been conducted by the National Center for Health Statistics for over forty years. The survey collects information on the health and nutritional status of the United States population using in-person interviews and standardized physical examinations conducted in mobile examination centers. During the course of these forty years, numerous lessons have been learned about the conduct of a survey using direct physical measures. Examples of these "lessons learned" are described and provide a guide for other organizations and countries as they plan similar surveys.

A large part of sample survey theory has been directly motivated by practical problems encountered in the design and analysis of sample surveys. On the other hand, sample survey theory has influenced practice, often leading to significant improvements. This paper will examine this interplay over the past 60 years or so.
Release date: 2007-03-02 - 30. Taking stock: the future of longitudinal surveys ArchivedArticles and reports: 11-522-X20050019469Description:
The 1990s was the decade of longitudinal surveys in Canada. The focus was squarely on the benefits that could be derived from the increased analytical power of longitudinal surveys. This presentation explores issues of insights gained, timeliness, data access, survey design, complexity, research capacity, survey governance and knowledge mobilisation. This presentation outlines some of the issues that are likely to be raised in any debate regarding longitudinal surveys.
