  • 1. Research on Modifications to the Method of Preliminary Estimates of Interprovincial Migration Archived
    Articles and reports: 91F0015M2005007
    Geography: Canada
    Description:

    The Population Estimates Program at Statistics Canada is using internal migration estimates derived from administrative sources of data. There are two versions of migration estimates currently available, preliminary (P), based on Child Tax Credit information and final (F), produced using information from income tax reports. For some reference dates they could be significantly different. This paper summarises the research undertaken in Demography Division to modify the current method for preliminary estimates in order to decrease those differences. After a brief analysis of the differences, six methods are tested: 1) regression of out-migration; 2) regression of in- and out-migration separately; 3) regression of net migration; 4) the exponentially weighted moving average; 5) the U.S. Bureau of Census approach; and 6) method of using the first difference regression. It seems that the methods in which final and preliminary migration data are combined to estimate preliminary net migration (Method 3) are the best approach to improve convergence between preliminary and final estimates of internal migration for the Population Estimation Program. This approach allows for "smoothing" of some erratic patterns displayed by the former method while preserving CTB data's ability to capture current shifts in migration patterns.

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.
