    Description:

    This article provides a description of the Canadian Census Health and Environment Cohorts (CanCHECs), a population-based linked datasets of the household population at the time of census collection. The CanCHEC datasets are rich national data resources that can be used to measure and examine health inequalities across socioeconomic and ethnocultural dimensions for different periods and locations. These datasets can also be used to examine the effects of exposure to environmental factors on human health.

    Description:

    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:

    This study looks at changes introduced in 2018 to the methodology used for the census family low income measure, based on the T1 Family File (T1FF; tax filer data). By making these changes, the methodology becomes better aligned with other data sources at Statistics Canada, such as the Census of Population and the Canadian Income Survey. To account for changes in the methodology, new T1FF standard tables on the census family low income measure (after-tax income), going back to 2004 data, are introduced.

    Description:

    This study looks at the differences in after-tax low income measure (LIM) statistics from two data sources which both use administrative tax data as their principal inputs: the 2016 Census of Population and the T1 Family file (T1FF). It presents a summary of the two data sources and compares after-tax LIM statistics by focussing on unit of analysis, LIM thresholds and the percentage of population below the LIM. The study also explores what factors users may want to consider when choosing one data source over the other.

    Description:

    Record linkage has been identified as a potential mechanism to add treatment information to the Canadian Cancer Registry (CCR). The purpose of the Canadian Cancer Treatment Linkage Project (CCTLP) pilot is to add surgical treatment data to the CCR. The Discharge Abstract Database (DAD) and the National Ambulatory Care Reporting System (NACRS) were linked to the CCR, and surgical treatment data were extracted. The project was funded through the Cancer Data Development Initiative (CDDI) of the Canadian Partnership Against Cancer (CPAC).

    The CCTLP was developed as a feasibility study in which patient records from the CCR would be linked to surgical treatment records in the DAD and NACRS databases, maintained by the Canadian Institute for Health Information. The target cohort to whom surgical treatment data would be linked was patients aged 19 or older registered on the CCR (2010 through 2012). The linkage was completed in Statistics Canada’s Social Data Linkage Environment (SDLE).

    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.

    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:

    The National Children’s Study Vanguard Study was a pilot epidemiological cohort study of children and their parents. Measures were to be taken from pre-pregnancy until adulthood. The use of extant data was planned to supplement direct data collection from the respondents. Our paper outlines a strategy for cataloging and evaluating extant data sources for use with large scale longitudinal. Through our review we selected five evaluation factors to guide a researcher through available data sources including 1) relevance, 2) timeliness, 3) spatiality, 4) accessibility, and 5) accuracy.

    Description:

    More and more data are being produced by an increasing number of electronic devices physically surrounding us and on the internet. The large amount of data and the high frequency at which they are produced have resulted in the introduction of the term ‘Big Data’. Because of the fact that these data reflect many different aspects of our daily lives and because of their abundance and availability, Big Data sources are very interesting from an official statistics point of view. However, first experiences obtained with analyses of large amounts of Dutch traffic loop detection records, call detail records of mobile phones and Dutch social media messages reveal that a number of challenges need to be addressed to enable the application of these data sources for official statistics. These and the lessons learned during these initial studies will be addressed and illustrated by examples. More specifically, the following topics are discussed: the three general types of Big Data discerned, the need to access and analyse large amounts of data, how we deal with noisy data and look at selectivity (and our own bias towards this topic), how to go beyond correlation, how we found people with the right skills and mind-set to perform the work, and how we have dealt with privacy and security issues.

    Description:

    Accurate information about the timing of access to primary mental health care is critically important in order to identify potentially modifiable factors which could facilitate timely and on-going management of care. No "gold standard" measure of mental health care utilization exists, so it useful to know how strengths, gaps, and limitations in different data sources influence study results. This study compares two population-wide measures of primary mental health care utilization data: the Canadian Community Health Survey of Mental Health and Well-being (CCHS, cycle 1.2) and provincial health insurance records in the province of British Columbia. It explores four questions: (1) Is 12-month prevalence of contacts with general practitioners for mental heath issues the same regardless of whether survey data or administrative data are used? (2) What is the level of agreement between the survey data and administrative data for having had any contact with a general practitioner for mental heath issues during the 12 month period before the survey interview? (3) Is the level of agreement constant throughout the 12-month period or does it decline over more distant sub-timeframes within the 12-month period? (4) What kinds of respondent characteristics, including mental disorders, are associated with agreement or lack of agreement? The results of this study will provide useful information about how to use and interpret each measure of health care utilization. In addition, it will contribute to survey design research, and to research which aims to improve the methods for using administrative data for mental health services research.
