The Longitudinal Immigration Database combines linked administrative immigration and tax data files. It is a comprehensive source of data on the socio-economic outcomes of the immigrant taxfiler population in Canada. In partnership with Immigration, Refugees and Citizenship Canada (IRCC) and the national network of Local Immigration Partnerships (LIP), the Community Data Program has acquired a set of data tables tracking the mobility and economic outcomes of Canada's newcomer population over several years.
This catalogue entry is for IMDB Table 10 out of 10 and contains data for LIP boundary geographies. IMDB data tables are available at the Census Subdivision and Census Division levels as well as for a number of custom LIP boundaries. The table contents are described below, by table number:
- LIP boundaries - Immigrant taxfiler income and mobility by sex, socio-demographic profile, admission year and tax year, for Canada, select provinces/territories and partnerships
- Census Subdivisions - Immigrant taxfiler mobility by knowledge of official languages, immigrant admission category, age and sex, admission year and tax year, for Canada and census subdivisions
- Census Subdivisions - Immigrant taxfiler mobility by world area, immigrant admission category, age and sex, admission year and tax year, for Canada and census subdivisions
- Census Subdivisions - Immigrant taxfiler mobility by socio-demographic profile, immigrant admission category, age and sex, admission year and tax year, for Canada and census subdivisions
- Census Subdivisions - Immigrant taxfiler income by knowledge of official languages, immigrant admission category, age and sex, admission year and tax year, for Canada and census subdivisions
- Census Subdivisions - Immigrant taxfiler income by world area, immigrant admission category, age and sex, admission year and tax year, for Canada and census subdivisions
- Census Subdivisions - Immigrant taxfiler income by socio-demographic profile, immigrant admission category, age and sex, admission year and tax year, for Canada and census subdivisions
- Census Divisions - Immigrant taxfiler mobility by socio-demographic profile, immigrant admission category, age and sex, admission year and tax year, for Canada and census divisions
- Census Divisions - Immigrant taxfiler income by socio-demographic profile, immigrant admission category, age and sex, admission year and tax year, for Canada and census divisions
- LIP boundaries - Immigrant mobility, by age and sex, knowledge of official languages at admission, pre-admission experience, immigrant admission category, admission year and tax year, for custom LIP geographies
Note that the same data are available for Census Subdivision as Census Division, however the Census Subdivision data needed to be broken out into multiple tables.
The geographies used in these tables are all based on 2016 Census boundaries.
Note that the data in the IMDB tables shows counts for immigrant taxfilers aged 15 and over. Immigrants aged 0-14 and those who have not filed taxes are not captured.
The retention rate for a given geography is the proportion of immigrants (filing taxes, aged 15+) from a given admission year who are located in their "intended geography" when they filed taxes for a given tax year. The "intended geography" is the location where the immigrant indicated that they would be going upon admission.
Retention rate can be calculated as follows (using variables from the IMDB tables):
retention rate = stay / (stay + out migration)
Out migration only counts those immigrants who are not residing in their intended geography for a given tax year. It does not count immigrants who moved into that geography and subsequently left. If an immigrant moved back into their intended geography, they would be counted in the "stay" column (for that tax year, but not for the tax years they were gone).
Note that the national and provincial retention rates included in these tables are not calculated using the above formula and provide an average retention rate for all the geographies, respectively in the country or relevant province. Provincial retention rates can be obtained either by using Statistics Canada's Longitudinal Immigration Database [IMDB] Interactive Application: Mobility OR from this table: Interprovincial migration of immigrant taxfilers, by pre-admission experience and tax year, for Canada and provinces.
