The full sample of 160,847 households is surveyed over a four
month period. Therefore, the most comprehensive measure of consumer
sentiments can be produced at the end of execution of the survey over
all these households. However, the execution of the survey is planned and
executed in a manner that enables the estimation of consumer sentiments
at a monthly frequency also. The sample size of 40,200 household per
month is well distributed over the country to enable the estimation of
monthly consumer sentiment indices.
Further, execution of the monthly sample is well-distributed
over rural and urban regions to enable a weekly estimation of consumer
sentiments at the all-India level. About 10,000 households are surveyed
Our ultimate goal is to be able to generate daily consumer
sentiment indices since the sample size of about 1,400 households and
its distribution does raise the possibility of doing so.
Besides the large sample, technology and precision in execution
enable the production of daily consumer sentiment indices. However,
as a matter of caution, we begin with the estimation of a 30-day moving
We compute the 30-day moving average of consumer sentiment
indices in India every day, using the data collected during the preceding
30 days. Detailed description of the survey design, the data file,
estimation methodology, the R program and a sample data file is provided
separately to ensure complete transparency.
