The National Sample Survey (NSS) is a national socioeconomic survey conducted in annual rounds with a cycle of rotating topics. In the 66th Round, July 2009 to June 2010, the NSS included two schedules: household consumer expenditure (type 1 and type 2) and employment.

The household consumer expenditure survey used two versions of the standard Schedule 1.0, with recall periods of 30 and 7 days and samples of 100,855 and 100,794 households, respectively. The employment survey sampled 100,957 households.

The survey sample was representative at the national and state levels, excluding select areas due to geographic remoteness.
