Report of the Committee to verify the reliability and validity of the State of the Nations Survey (July 2011) conducted in Andhra Pradesh
Concerns were raised about the findings of the survey conducted by the Center for the Study of Developing Societies (CSDS) between the 24th and 30th July 2011 regarding the extent of support for a separate Telangana state. An independent review committee was set to assess the neutrality and accuracy of this study. The committee found no evidence of any systematic bias in the drawing of the sample or any noticeable internal inconsistencies in the survey data
