- 1. Towards an integrated census-administrative data approach to item-level imputation for the 2021 UK Census ArchivedArticles and reports: 11-522-X201700014715Description:
In preparation for 2021 UK Census the ONS has committed to an extensive research programme exploring how linked administrative data can be used to support conventional statistical processes. Item-level edit and imputation (E&I) will play an important role in adjusting the 2021 Census database. However, uncertainty associated with the accuracy and quality of available administrative data renders the efficacy of an integrated census-administrative data approach to E&I unclear. Current constraints that dictate an anonymised ‘hash-key’ approach to record linkage to ensure confidentiality add to that uncertainty. Here, we provide preliminary results from a simulation study comparing the predictive and distributional accuracy of the conventional E&I strategy implemented in CANCEIS for the 2011 UK Census to that of an integrated approach using synthetic administrative data with systematically increasing error as auxiliary information. In this initial phase of research we focus on imputing single year of age. The aim of the study is to gain insight into whether auxiliary information from admin data can improve imputation estimates and where the different strategies fall on a continuum of accuracy.

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.
Release date: 2016-03-24 - 3. Estimating the Impact of Active Labour Market Programs using Administrative Data and Matching Methods ArchivedArticles and reports: 11-522-X201700014740Description:
In this paper, we discuss the impacts of Employment Benefit and Support Measures delivered in Canada under the Labour Market Development Agreements. We use linked rich longitudinal administrative data covering all LMDA participants from 2002 to 2005. We Apply propensity score matching as in Blundell et al. (2002), Gerfin and Lechner (2002), and Sianesi (2004), and produced the national incremental impact estimates using difference-in-differences and Kernel Matching estimator (Heckman and Smith, 1999). The findings suggest that, both Employment Assistance Services and employment benefit such as Skills Development and Targeted Wage Subsidies had positive effects on earnings and employment.

This study presents the results of a hierarchical exact matching approach to link the 2006 Census of Population with hospital data for all provinces and territories (excluding Quebec) to the 2006/2007-to-2008/2009 Discharge Abstract Database. The purpose is to determine if the Census–DAD linkage performed similarly in different jurisdictions, and if linkage and coverage rates declined as time passed since the census.

This study examines the feasibility and limitations of applying a non-categorical approach (focused on service utilization rather than on specific diagnoses) to administrative data in order to identify children with health problems.
Release date: 2015-02-18 - Articles and reports: 11-522-X201300014268Description:
Information collection is critical for chronic-disease surveillance to measure the scope of diseases, assess the use of services, identify at-risk groups and track the course of diseases and risk factors over time with the goal of planning and implementing public-health programs for disease prevention. It is in this context that the Quebec Integrated Chronic Disease Surveillance System (QICDSS) was established. The QICDSS is a database created by linking administrative files covering the period from 1996 to 2013. It is an attractive alternative to survey data, since it covers the entire population, is not affected by recall bias and can track the population over time and space. In this presentation, we describe the relevance of using administrative data as an alternative to survey data, the methods selected to build the population cohort by linking various sources of raw data, and the processing applied to minimize bias. We will also discuss the advantages and limitations associated with the analysis of administrative files.

Release date: 2009-12-03 - 8. Evaluation of the coverage of linked Canadian Community Health Survey and hospital inpatient records ArchivedArticles and reports: 11-522-X200800010972Description:
Background: Evaluation of the coverage that results from linking routinely collected administrative hospital data with survey data is an important preliminary step to undertaking analyses based on the linked file. Data and methods: To evaluate the coverage of the linkage between data from cycle 1.1 of the Canadian Community Health Survey (CCHS) and in-patient hospital data (Health Person-Oriented Information or HPOI), the number of people admitted to hospital according to HPOI was compared with the weighted estimate for CCHS respondents who were successfully linked to HPOI. Differences between HPOI and the linked and weighted CCHS estimate indicated linkage failure and/or undercoverage. Results: According to HPOI, from September 2000 through November 2001, 1,572,343 people (outside Quebec) aged 12 or older were hospitalized. Weighted estimates from the linked CCHS, adjusted for agreement to link and plausible health number, were 7.7% lower. Coverage rates were similar for males and females. Provincial rates did not differ from those for the rest of Canada, although differences were apparent for the territories. Coverage rates were significantly lower among people aged 75 or older than among those aged 12 to 74.

The Federation of Canadian Municipalities' (FCM) Quality of Life Reporting System (QOLRS) is a means by which to measure, monitor, and report on the quality of life in Canadian municipalities. To address that challenge of administrative data collection across member municipalities the QOLRS technical team collaborated on the development of the Municipal Data Collection Tool (MDCT) which has become a key component of QOLRS' data acquisition methodology. Offered as a case study on administrative data collection, this paper argues that the recent launch of the MDCT has enabled the FCM to access reliable pan-Canadian municipal administrative data for the QOLRS.

Release date: 2009-12-03 - 10. Project on Matching Census 1986 Database and Manitoba Health Care Files: Private Households Component ArchivedArticles and reports: 11F0019M1996091Geography: Province or territoryDescription:
Introduction: In the current economic context, all partners in health care delivery systems, be they public or private, are obliged to identify the factors that influence the utilization of health care services. To improve our understanding of the phenomena that underlie these relationships, Statistics Canada and the Manitoba Centre for Health Policy and Evaluation have just set up a new database. For a representative sample of the population of the province of Manitoba, cross-sectional microdata on individuals' health and socio-economic characteristics were linked with detailed longitudinal data on utilization of health care services.
Data and methods: The 1986-87 Health and Activity Limitation Survey, the 1986 Census and the files of Manitoba Health were matched (without using names or addresses) by means of the CANLINK software. In the pilot project, 20,000 units were selected from the Census according to modern sampling techniques. Before the files were matched, consultations were held and an agreement was signed by all parties in order to establish a framework for protecting privacy and preserving the confidentiality of the data.
Results: A matching rate of 74% was obtained for private households. A quality evaluation based on the comparisons of names and addresses over a small subsample established that the overall concordance rate among matched pairs was 95.5%. The match rates and concordance rates varied according to age and household composition. Estimates produced from the sample accurately reflected the socio-demographic profile, mortality, hospitalization rate, health care costs and consumption of health care by Manitoba residents.
Discussion: The matching rate of 74% was satisfactory in comparison with the response rates reported in most population surveys. Because of the excellent concordance rate and the accuracy of the estimates obtained from the sample, this database will provide an adequate basis for studying the association between socio-demographic characteristics, health and health care utilization in province of Manitoba.
