Nowadays, health inequalities are emerging at short geographic distances, even among the districts of a city in developed and developing countries. In response to these conditions, it is important to study the role of socioeconomic structures and factors in the incidence and distribution of health outcomes.

The present paper examines the evidence of health inequalities at international and regional levels and explains its reasons.
