Generally, the unequal or unjust distribution of resources and opportunities in a society is studied in just one dimension, such as through income or education, says Maralani. Yet inequalities in income, wealth, education, health and access to technology are inter-related and differ by gender, race , ethnicity and geographical location in important ways. The root causes are multidimensional and dynamic.
