Social inequality is pervasive in contemporary human societies. Nevertheless, there is a view that livestock, as the primary source of wealth, limits the development of inequalities, making pastoralism unable to support complex or hierarchical organisations. Thus, complex nomadic pastoral organisation is predominantly caused by external factors, i.e., historically nomadic political organisation mirrored the neighbouring sedentary population's sophistication. Using governmental statistics on reindeer herding in Norway (2001 - 2018), this study demonstrates nothing apparent in the pastoral adaptation with livestock as the main base of wealth that level wealth inequalities and limits social differentiation. This study found that inequality was generally decreasing in terms of the Gini coefficient and cumulative wealth. For example, the proportion owned by the wealthy decreased from 2001 to 2018, while the proportion owned by the poor increased. Nevertheless, rank differences persist over time with minor changes. Especially, being poor is stable: around 50% of households ranked as poor in 2001 continued to be so in 2018. In sum, results from this study indicate that pastoral wealth inequality follows the same patterns as all forms of wealth. Wealth accumulates over time, and because the highest earners can save much of their income (i.e., newborn livestock), low earners cannot. High earners can thus accumulate more and more wealth over time, leading to considerable wealth inequalities.
