  • 1. The estimation of gross flows in complex surveys with random nonresponse Archived
    Articles and reports: 12-001-X201400214113
    Description:

    Rotating panel surveys are used to calculate estimates of gross flows between two consecutive periods of measurement. This paper considers a general procedure for the estimation of gross flows when the rotating panel survey has been generated from a complex survey design with random nonresponse. A pseudo maximum likelihood approach is considered through a two-stage model of Markov chains for the allocation of individuals among the categories in the survey and for modeling for nonresponse.

  • 2. The challenges of producing statistics for the Web: sampling and automated data collection of webpage information in the Brazilian Web Archived
    Articles and reports: 11-522-X201300014255
    Description:

    The Brazilian Network Information Center (NIC.br) has designed and carried out a pilot project to collect data from the Web in order to produce statistics about the webpages’ characteristics. Studies on the characteristics and dimensions of the web require collecting and analyzing information from a dynamic and complex environment. The core idea was collecting data from a sample of webpages automatically by using software known as web crawler. The motivation for this paper is to disseminate the methods and results of this study as well as to show current developments related to sampling techniques in a dynamic environment.

  • 3. Making Use of Administrative, Big and Survey Data: An Assessment of the Quality of Canadian Wetland Databases Archived
    Articles and reports: 11-522-X201300014264
    Description:

    While wetlands represent only 6.4% of the world’s surface area, they are essential to the survival of terrestrial species. These ecosystems require special attention in Canada, since that is where nearly 25% of the world’s wetlands are found. Environment Canada (EC) has massive databases that contain all kinds of wetland information from various sources. Before the information in these databases could be used for any environmental initiative, it had to be classified and its quality had to be assessed. In this paper, we will give an overview of the joint pilot project carried out by EC and Statistics Canada to assess the quality of the information contained in these databases, which has characteristics specific to big data, administrative data and survey data.

  • 4. A Framework for the Evaluation of Administrative Data Archived
    Articles and reports: 11-522-X201300014284
    Description:

    The decline in response rates observed by several national statistical institutes, their desire to limit response burden and the significant budget pressures they face support greater use of administrative data to produce statistical information. The administrative data sources they must consider have to be evaluated according to several aspects to determine their fitness for use. Statistics Canada recently developed a process to evaluate administrative data sources for use as inputs to the statistical information production process. This evaluation is conducted in two phases. The initial phase requires access only to the metadata associated with the administrative data considered, whereas the second phase uses a version of data that can be evaluated. This article outlines the evaluation process and tool.

  • 5. Two approaches to linking census and hospital data Archived
    Articles and reports: 82-003-X201401014098
    Geography: Province or territory
    Description:

    This study compares registry and non-registry approaches to linking 2006 Census of Population data for Manitoba and Ontario to Hospital data from the Discharge Abstract Database.

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.

How are the results ordered?

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.
  • By title – sorts results alphabetically.
