1. Record linkage techniques to identify 2021 Canadian Census dwellings in the new Statistical Building Register Archived
Articles and reports: 11-522-X202200100020
Description: The reconciliation of 2021 census dwellings with the new Statistical Building Register (SBgR) presented linkage challenges. The Census of Population collected information from various dwelling types. For a large proportion of the population, mailing addresses were at the centre: they were used for reaching out to people and collected as contact info. In parallel, the register environment has been evolving. The agency is transitioning from the Address Register (AR) to the SBgR holding both mailing and location addresses, while also covering non-residential buildings. The reconciliation was conducted using a combination of systems, notably the new Register Matching Engine (RME) for difficult cases. The RME holds an interesting range of sophisticated string comparators. A deterministic linkage approach was used, while incorporating some data knowledge like the entropy. Through metadata, the matching expert could also reduce the amounts of false positives and false negatives.

2. Paid Employment, Self-employment and Gig Work in Administrative and Survey Data
Articles and reports: 11F0019M2023003
Description: This study combines survey and administrative data to examine the correspondence between paid-employment and self-employment activities reported in each of these data sources by the same individuals. The study also looks at the role of self-employment as a supplemental income source for individuals whose self-declared main labour market activity is wage employment.

4. Bayesian pooling for analyzing categorical data from small areas
Articles and reports: 12-001-X202100100005
Description:
Bayesian pooling strategies are used to solve precision problems related to statistical analyses of data from small areas. In such cases, the subpopulation samples are usually small, even though the population might not be. As an alternative, similar data can be pooled in order to reduce the number of parameters in the model. Many surveys consist of categorical data on each area, collected into a contingency table. We consider hierarchical Bayesian pooling models with a Dirichlet process prior for analyzing categorical data based on small areas. However, the prior used to pool such data frequently results in an overshrinkage problem. To mitigate for this problem, the parameters are separated into global and local effects. This study focuses on data pooling using a Dirichlet process prior. We compare the pooling models using bone mineral density (BMD) data taken from the Third National Health and Nutrition Examination Survey for the period 1988 to 1994 in the United States. Our analyses of the BMD data are performed using a Gibbs sampler and slice sampling to carry out the posterior computations.

5. International population-based health surveys linked to outcome data: A new resource for public health and epidemiology
Articles and reports: 82-003-X202000700002
Description:
This paper's objectives are to examine the feasibility of pooling linked population health surveys from three countries, facilitate the examination of health behaviours, and present useful information to assist in the planning of international population health surveillance and research studies.

6. Measuring the Gig Economy in Canada Using Administrative Data
Articles and reports: 11F0019M2019025
Description:
This study identifies gig workers based on characteristics of their work arrangements and how these are reported in tax data. It introduces a definition of gig work specific to the way work arrangements are reported in the Canadian tax system and estimates the size of the gig economy in Canada using administrative data. The share of gig workers among all workers rose from 5.5% in 2005 to 8.2% in 2016. Some of this increase coincided with the introduction and proliferation of online platforms. The analysis highlights gender differences in the trends and characteristics of gig workers. By linking administrative data to 2016 Census microdata, this study also examines educational and occupational differences in the prevalence of gig workers.

7. On combining independent probability samples
Articles and reports: 12-001-X201900200003
Description:
Merging available sources of information is becoming increasingly important for improving estimates of population characteristics in a variety of fields. In presence of several independent probability samples from a finite population we investigate options for a combined estimator of the population total, based on either a linear combination of the separate estimators or on the combined sample approach. A linear combination estimator based on estimated variances can be biased as the separate estimators of the population total can be highly correlated to their respective variance estimators. We illustrate the possibility to use the combined sample to estimate the variances of the separate estimators, which results in general pooled variance estimators. These pooled variance estimators use all available information and have potential to significantly reduce bias of a linear combination of separate estimators.

8. Variance estimation under monotone non-response for a panel survey Archived
Articles and reports: 12-001-X201800254952
Description:
Panel surveys are frequently used to measure the evolution of parameters over time. Panel samples may suffer from different types of unit non-response, which is currently handled by estimating the response probabilities and by reweighting respondents. In this work, we consider estimation and variance estimation under unit non-response for panel surveys. Extending the work by Kim and Kim (2007) for several times, we consider a propensity score adjusted estimator accounting for initial non-response and attrition, and propose a suitable variance estimator. It is then extended to cover most estimators encountered in surveys, including calibrated estimators, complex parameters and longitudinal estimators. The properties of the proposed variance estimator and of a simplified variance estimator are estimated through a simulation study. An illustration of the proposed methods on data from the ELFE survey is also presented.

9. The DYSEM Microsimulation Modelling Platform Archived
Articles and reports: 11-633-X2017008
Description:
The DYSEM microsimulation modelling platform provides a demographic and socioeconomic core that can be readily built upon to develop custom dynamic microsimulation models or applications. This paper describes DYSEM and provides an overview of its intended uses, as well as the methods and data used in its development.

10. Statistics Canada and Open Data Archived
Articles and reports: 11-522-X201700014720
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.)

1. Revisions of the Canadian National Tourism Indicators Archived
Stats in brief: 13-604-M2005047
Description:
This paper discusses the revision policy of Canada's National Tourism Indicators (NTI) and summarizes results from some recent studies of data revisions to the NTI. The discussion is timely, as the adoption of explicit data revision policies has been emphasized recently as an essential element in the good governance of statistical systems.
The paper starts with a brief description of the NTI, their underlying conceptual framework, and their sources and methods. Next comes a discussion of the need for data revisions, and an outline of various types of revisions. Then a few sections are devoted to the new NTI revision policy adopted with the first quarter 2004 estimates, and the associated costs and benefits. Revision studies, which have been used to assess quality of national accounts estimates, and the database established to track data revisions to the NTI are described next. Last, results from some recent NTI data revision exercises and studies are summarized.
