Totals and sub-totals are suppressed when the value falls within scope of the suppression criteria, or when the summary value includes a single suppressed figure, in order to prevent the inadvertent disclosure of suppressed values.
The confidentiality constraints and use of the "Unreliable" flag are established by the original data providers. For more information, please contact the data providers.
