National Household Survey (NHS)

The National Household Survey (NHS) was a voluntary survey (not required by law) that replaced the annual census in 2011.  The topics of the survey included Aboriginal Peoples, Immigration and Ethnocultural Diversity, Education and Labour, Mobility and Migration, Language of Work, and Income and Housing. As the survey was not mandatory, fewer responses were recorded than in previous years, and the annual census has since been reinstated as the primary survey. NHS data is used only for datasets in 2011.
