Abstract
The population issue is one of the most complex subjects to analyze since all the science dimensions are related to it in varied proportions. In this chapter, population is analyzed according to consumer income and expenditure. Both the dynamics and disparities among countries regarding population, income, and expenditure are studied and multiple analyses from different views are undertaken. Given the numerous categories of consumer expenditure, only the food and non-alcoholic beverage consumer expenditure category is researched, in this chapter, both from a general perspective and from a narrower viewpoint restricted to each class. Several forecasts of the consequences of increasing the rice, wheat, corn, and coffee consumption are made.
