Glossary Definition

Last Updated: 2010-10-21


A group of individuals who cannot be assigned a neighbourhood income from census data, and are therefore excluded from all neighbourhood income quintile analyses. Individuals included in the "Income Unknown" group include:

  • residents of long-term care facilities,
  • residents of some personal care homes,
  • residents of psychiatric facilities,
  • federal and long-term prisoners,
  • wards of the Public Trustee and Child and Family Services, and
  • residents of various areas reporting no income in the census.
NOTE: For the census, Statistics Canada suppresses average household income values for dissemination areas (DA) with populations less than 250 persons: these are grouped into income unknown for analyses using the census.
