Datasets consists of the data collected by the National Sample Survey (NSS) Organization, India, NSS 46th round collected in 1990-91; NSS 56th round collected in 2000-01; NSS 63rd round collected in 2006-07; and NSS 68th round collected in 2011-12. Since the inception of the National Sample Survey Organization (NSSO) in 1950, the Institute collects information on consumer expenditure, employment, and unemployment on a regular basis. To enhance precision in data collection, NSSO implements a stratified multi-stage sampling designing approach. In the NSS 46th round of data (1990-91), out of the 28,533 surveyed households, only 57 reportedly used biogas for cooking. The number of households that supposedly used biogas for cooking in the NSS 56th round of data (2000-01) was 160, out of the total number of households surveyed which was 81,500. Similarly, in the NSS 63rd round of data (2006-07), 63,729 households were surveyed, but only 129 reportedly used biogas, and in the NSS 68th round of data (2011-12), 101,662 households were surveyed, and 148 households reportedly used biogas (Table 2). It shows that the sub-sample of the households that reportedly used biogas are only a few among the total sampled households in the sampled NSS rounds. The econometric estimation process in characterizing the households that use biogas may not converge due to the non-proportional number of users and non-users of biogas among the households sampled. To solve the problem, we have randomly grouped the sampled households in each NSS round into 100 sub-groups, and chose only the sub-sample in the first group, and merged them with the sub-sample of the households who reportedly used biogas. In the process, for example in the case of the NSS 46th round of data, we have divided 28,476 households into 100 random groups. Each group consists of 284 households. We merged the 57 biogas-user households with 284 randomly chosen households from 28,476 total sampled households of NSS 46th round. Thus, the process provides us with 341 sub-sample households from the NSS 46th round of data. In the same process, we have considered 965 sub-samples from 81,500 sampled households from the NSS 56th round data; 762 sub-samples from 63,729 sampled households from the NSS 63rd round of data and 1,016 sub-samples from 101,662 sampled households from the NSS 68th round of data (Table 2). This study, thus, relies on information collected from sub-samples of 3,232 households from India, of which 1,764 (54.6%) were from rural areas, and 1,468 (45.4%) were from the urban areas
