CMIE Consumer Pyramidsdx

Survey Design

The record-level data in Consumer Pyramids dx is from the panel of households in CMIE’s Consumer Pyramids survey. CMIE’s Consumer Pyramids panel of households contains about 160,000 households.

The Consumer Pyramids survey is conducted all over the country, except in the following north eastern states - Arunachal Pradesh, Nagaland, Manipur, Mizoram, Tripura, Meghalaya and Sikkim and in Andaman & Nicobar Islands, Dadra & Nagar Haveli, Lakshadweep and Daman and Diu. The survey covers Assam, Kashmir and all other parts of the country.

A stratified multi-stage survey design was deployed by CMIE to draw its sample of households.

The Primary Sampling Units (PSUs) were the villages and towns of the 2011 Census. The Ultimate Sampling Units (USUs) were the households from these PSUs.

The broadest level of strata for sampling purpose was the Homogeneous Region (HR), which is a set of neighbouring districts that have similar agro-climatic conditions, urbanisation levels and female literacy. HRs are also approximately of the same size, except in the north east, where the entire set of north-eastern states is considered as one HR.

The sub-strata are the rural and urban regions within each strata, i.e within each HR.

The sampling frame for rural PSUs was the list of villages as of the 2011 Census. The sampling frame for urban PSUs was the list of towns as of the 2011 Census.

Within each HR, two strata were formed - a rural stratum comprising all villages in the HR; and an urban stratum comprising all towns in the HR. However, since there is much variance in the size of towns, towns within a HR were stratified further on the basis of their size. All towns of an HR were stratified into four strata based on the number of households in 2011, as follows:

  1. Very large towns had more than 200,000 households.
  2. Large towns had between 60,000 and 200,000 households.
  3. Medium sized households had between 20,000 and 60,000 households
  4. Those with less than 20,000 households were the small towns.

One or more towns were randomly selected from each of these size-bins. A total of 325 towns were selected through this process.

From each of these towns, 21 Census Enumeration Blocks (CEB) were randomly selected. A CEB is a cluster of about 100-125 neighbouring households. Households were then selected through a process of systematic random sampling from each of the CEBs. A total of 7,579 CEBs and 112,024 urban households were selected through this process.

Like the urban sample, the rural sample selection is also a two-staged sampling process. The first step in the design is to select villages and then the final step is to select households. Villages were selected through simple random sampling process. Villages are the PSUs. Households were selected from these through a process of systematic random sampling from each selected village.

Rural India is surveyed in 97 HRs. The rural sample comprises 46,600 households from 2,844 villages.
