Dependency of Market and Non Market sources of tribal's consumption: a time series Analysis

The tribes are generally under developed and limited in their productivity and as they are living close to the nature, they are generally unable to produce any substantial surplus according to their necessity. If we view consumption as an activity of combining market and non-market elements with the aim to analyse the changing phenomenon of the sources of consumption we have make a border between market and non-market components of the consumption process and to consider the interrelations of marketed and non-marketed consumption of the tribes. So far as the present study on consumption expenditure is concerned, we are to depend mainly on the unit level data of National Sample Survey over the different rounds as the NSSO data of 50, 61, 66 & 68 NSS data. As our study has been based on NSSO Unit Level data this paper analyse the changing variation of non-market market consumption of tribal. The study has been viewed with the time allocation approach that consumption acts as a process. This study has been based on rural tribes of Purulia, Bankura and Midnapur districts of West Bengal. as per the availability of unit level data sources from NSSO.
