Overview

Summary

The Longitudinal Immigration Statistical Environment (LISE) is a record linkage environment connecting administrative and survey data from multiple subject matter areas to the Longitudinal Immigration Database (IMDB) and Longitudinal Administrative Databank (LAD). The linkage to the IMDB or the LAD allows for a variety of analytical possibilities. The IMDB provides a longitudinal socio-economic profile of immigrants admitted to Canada since 1952, including information on those receiving non-permanent resident permits since 1980, and tax records since 1982. The LAD, which provides a comparison group of Canadians, is a random, 20% sample of the T1 Family File (T1FF) tax database available since 1982 containing demographics, income, and other taxation data for a subset of Canadians, allowing the creation of a longitudinal profile of each individual. The LISE provides a repository of linkage keys for the IMDB and LAD to administrative and survey data from multiple subject matter areas. Potential linkages are: Health administrative databases - Discharge Abstract Database (DAD), National Ambulatory Care Reporting System (NACRS), and Ontario Mental Health Reporting System (OMHRS), which allows the exploration of healthcare utilization over time by immigrants and Canadians. Depending on the database used, outcomes could include acute care institution visits from the DAD, ambulatory care visits from the NACRS, mental health institution services used by individuals captured in the OMHRS, among others. Education administrative databases - Postsecondary Student Information System (PSIS) and Registered Apprenticeship Information System (RAIS), which provides longitudinal outcomes for immigrant or Canadian cohorts in terms of post-secondary enrolment and graduation information from the PSIS, and for registered apprenticeship certifications from the RAIS. Census of Population 2016 and 2021, which can provide sociodemographic information and outcomes for immigrant or Canadian cohorts. Additionally, migration and mobility analysis of individuals from the IMDB or the LAD is also available using annual information on place of residence. Included in this release: Health Outcome Linkages: 2022 LAD (1982-2022) linked to DAD (1994 - 2023), NACRS (2002– 2023), and OMHRS (2006-2023) 2023 IMDB linked to DAD (1994 - 2023), NACRS (2002– 2023), and OMHRS (2006-2023) The LISE linkages with education and census data will be released at a later date. Information for Data Access: Requests to access LISE data must be immigration focused. The LISE provides access to pair-wise linkages of IMDB or LAD to outcome files (e.g., IMDB to DAD and LAD to DAD). RDC users interested in a specific pair need to request access to a minimum of 2 data products to build the analytical dataset: 1) cohort file (IMDB or LAD), 2) outcome file (DAD, NACRS, OMHRS), For example: IMDB All Years and LISE_IMDB_DAD_AllYears. Researchers can now request access to more than one linkage at a time. For example: IMDB linked to DAD and IMDB linked to NACRS.
