Starting with the 2011 Census, Statistics Canada replaced a mandatory long-form questionnaire with a voluntary National Household Survey. This survey gives insight into core social indicators of Canadian society, including aboriginal peoples, immigration and ethnocultural diversity, education and labour, mobility and migration, and income and housing.

The data are coded and documented consistently across countries and over time to facillitate comparative research.
