Social inequality. Social inequality is an area within sociology that focuses on the distribution of goods and burdens in society. A good can be, for example, income, education, employment or parental leave, while examples of burdens are substance abuse, criminality, unemployment and marginalisation. One approach is the study of the actual distribution of a good. For example, whether incomes are reasonably evenly distributed throughout a community or whether there are sizable differences between those that relatively little and those that earn relatively much.
