The Hospital Episode Statistics for admitted patient care (HES-APC) data uses census notation based on the 2001 Census. ‘Z: not stated’ indicates that the person was asked and either refused to provide this information or was genuinely unable to choose a response. ‘X: Not known’ indicates that the person was not asked or was not in a condition to be asked (e.g., unconscious).
