Census Profile - Area and data suppression

In addition to random rounding, area and data suppression has been adopted to further protect the confidentiality of individual respondents' personal information.

Area and data suppression results in the deletion of all information for geographic areas with populations below a specified size. For example, areas with a population of less than 40 persons are suppressed. If the community searched has a population of less than 40 persons, only the total population counts will be available. Suppression of data can be due to poor data quality or to other technical reasons.
