The Longitudinal Immigration Database (IMDB) includes administrative immigration data for all immigrants since 1952 and non-permanent residents since 1980. Outcomes for this population are available from tax files since 1982. The IMDB provides detailed and reliable information on socioeconomic outcomes of immigrants after their admission, such as employment income and mobility. It connects short- and long-term outcomes with characteristics at admission, such as immigrant admission category, source country and knowledge of official languages. 

The database also provides information on pre-admission experience in Canada, such as work or study permits as well as refugee claims. It now includes data about wages and salaries, immigrant children's family outcomes, settlement and resettlement services (information available since 2013), as well as citizenship acquisition (information available since 2004).
