The majority of hunter - gatherer societies are nomadic . It is difficult to be settled under such a subsistence system as the resources of one region can quickly become exhausted . Hunter - gatherer societies also tend to have very low population densities as a result of their subsistence system . Agricultural subsistence systems can support population densities 60 to 100 times greater than land left uncultivated , resulting in denser populations . Hunter - gatherer societies also tend to have non - hierarchical social structures , though this is not always the case . Because hunter - gatherers tend to be nomadic , they generally do not have the possibility to store surplus food . As a result , full - time leaders , bureaucrats , or artisans are rarely supported by hunter - gatherer societies .

Agricultural societies are more likely to be able to support denser populations . Because they are nomadic , hunter gatherers cannot store excess food , and are less likely to be able to support social hierarchies or specialized roles .
