New data for the Longitudinal Immigration Statistical Environment (LISE) are now available for download and can be accessed by researchers with approved projects. 

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). 

We have eased the restrictions on multi-file linkages to a base file (IMDB->DAD+NACRS).

 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:

1. 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.

2. 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. 

3. 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.
