  • 1. A grouping genetic algorithm for joint stratification and sample allocation designs
    Articles and reports: 12-001-X201900300007
    Description:

    Finding the optimal stratification and sample size in univariate and multivariate sample design is hard when the population frame is large. There are alternative ways of modelling and solving this problem, and one of the most natural uses genetic algorithms (GA) combined with the Bethel-Chromy evaluation algorithm. The GA iteratively searches for the minimum sample size necessary to meet precision constraints in partitionings of atomic strata created by the Cartesian product of auxiliary variables. We point out a drawback with classical GAs when applied to the grouping problem, and propose a new GA approach using “grouping” genetic operators instead of traditional operators. Experiments show a significant improvement in solution quality for similar computational effort.

  • 2. 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.

  • 3. Response mobility and the growth of the Aboriginal identity population, 2006-2011 and 2011-2016
    Articles and reports: 99-011-X2019002
    Description:

    This study examines the patterns of response mobility to the Aboriginal identifier questions from 2006 to 2011 and 2011 to 2016. Response mobility, in this context, refers to people providing different responses over time to the Census questions about Aboriginal identity.

  • 4. Upgrading and high school equivalency among the Indigenous population living off reserve Archived
    Articles and reports: 75-006-X201900100013
    Description:

    Among people who leave high school prior to completion, many return to formal schooling as adults. High school equivalency programs (such as a General Educational Development or Adult Basic Education program) give them the opportunity to go back and complete high school requirements. Using data from the 2017 Aboriginal Peoples Survey, this study examines the factors associated with upgrading and high school equivalency among the Aboriginal population living off reserve. It also examines whether high school equivalency or upgrading is associated with better educational and labour market outcomes.

  • 5. Results from the 2016 Census: Occupations with older workers Archived
    Articles and reports: 75-006-X201900100011
    Description:

    Over the past two decades, the share of the employed population aged 55 and over increased significantly. This study uses Census of Population and Labour Force Survey to examine the changing age composition of workers within the most prevalent occupations (with at least 10,000 workers), as well as the occupations that are increasing and decreasing in size most rapidly.

  • 6. Accessing the Canada Learning Bond: Meeting Identification and Income Eligibility Requirements Archived
    Articles and reports: 75F0002M2019007
    Description:

    Not having a Social Insurance Number (SIN) and not filing taxes may represent challenges to access government programs and supports such as the Canada Education Savings Grant (CESG) and the Canada Learning Bond (CLB). Limited data availability has prevented a full assessment of the extent of these access challenges. This study attempts to address this knowledge gap by analyzing overall differences in SIN possession and tax-filing uptake by family income, levels of parental education, family type and Indigenous identity of the child and age of children using the 2016 Census data augmented with tax-filing and Social Insurance Number possession indicator flags.

  • 7. Prevalence of laser beam exposure and associated injuries Archived
    Articles and reports: 82-003-X201900100001
    Description:

    An increasing number of consumer laser products are available to Canadians, many being purchased from online retailers. Of particular concern are high-powered, handheld laser devices. This study was conducted to assess the impact of this influx of laser products on the number of laser-associated injuries in Canada. Data are from the rapid response component of the 2014 Canadian Community Health Survey which collected data from 19,765 Canadians on the prevalence of laser product exposure and usage, the type of laser product used, and the incidence of eye or skin injuries.

Search help

How do I use the filters and the search box?

  • You can initiate a search by entering keywords or selecting filters (e.g., under Subject, Geography, etc.) on the left side of the page.

  • Filters can be used together or in any combination. Each time you select a filter, the results on the page are updated.

  • To start a new search, click on the Clear all button above the search box or deselect each filter.

  • Specified keywords and filters appear above the search box. You can deselect any or all the tags to refine or clear your search.

How do I refine my search?

  • You can enter keywords in the search box. It is not necessary to use “+” or “, “ or “AND”.

  • You can delete some or all of the keywords from your search string.

  • Quotes around keywords limit the search to a specific phrase.

    • For example, “labour force survey” will limit results to products containing this phrase.

  • Use “or” between keywords to obtain results that contain one or more search terms.

    • For example, labour or­ force or survey will limit results to products containing any or all of these words.

How does the search work?

  • This search looks for results that have your query term in the title, description, subject, geography, product number or other information about the product.

    • For example, when searching the term ‘Diseases’, all results with the word ‘Diseases’ in the title, description or tagged the subject appear.

  • The text within an article or publication are not searched. For full text searching of articles, use the site search.

Sort help

How are the results ordered?

The Sort by feature provides three options:

  • By date – sorts results by product release date starting with the most recent.
  • By relevance is only needed or beneficial when you use the search box and submit a search query. Results are ordered by a combination of where the search term appears in the content, e.g., if it appears in the title, it likely means the product is more relevant to your search; how up to date or new the content in the product is; how popular the product is; and other factors.
  • By title – sorts results alphabetically.

The Sort by feature provides four options:

  • By date – sorts results by product release date starting with the most recent.
  • By most popular – gives priority to results that are most frequently selected by users, followed by the most recent.
  • By relevance is only needed or beneficial when you use the search box and submit a search query. Results are ordered by a combination of where the search term appears in the content, e.g., if it appears in the title, it likely means the product is more relevant to your search; how up to date or new the content in the product is; how popular the product is; and other factors.
