Herbert Spencer has defined simple society as one which forms a simple working whole unsubjected to any other and of which the parts cooperate for certain public ends. Simple societies have low division of labour.The occupational differentiation being limited primarily to birth, sex and age. These societies have no specialized economic organization.

The productive skills are simple and productivity is low therefore these societies cannot sustain large population size. Most of the adult members are engaged in food gathering activities.

There is little or no surplus so the social inequalities are not significant and economic interaction takes place within egalitarian frame-work.

The production system is simple but exchange of goods and services assume a complex form. The forms of exchange are reciprocal and redistributive type.

Some of the simple societies inhabiting regions having abundant food and other resources indulge in conspicuous consumption.
