Fact Sheet Data Obtained from Large Scale Annual Health Survey 2010-11 conducted in Chhattisgarh State of India

The following table is an extract of recently published Fact Sheet of Annual Health Survey 2010-11 by the Office of Registrar General of India.  This is regarding Chhattisgarh State of India.  To me it is depicting data collection flaw and then not validating the same.  The number of persons having some symptoms of a Chronic Illness can not be less than those getting diagnosed.  It is happening even at the state level (macro level) for Chhattisgarh.  At the district level it is observed even for many districts of Empowered Action Group States and Assam.  Probably, it is the assumption taken while formulating the concerned Household Schedule that both symptoms and the diagnosis of chronic illness are independent of each other.  But this is rubbish, a person having some symptoms only approaches a doctor for diagnosis of chronic illness and those having no symptoms will get a label of a particular chronic illness is very strange.  As per the data, this is happening more in urban areas.  People tend to tell their chronic illness without narrating the symptoms.  Data needed desired validation checks before analysis.
