As countries industrialize and the average households becoming wealthier, it makes sense that households would begin spending less and less of their income on food and drink, and more on less necessary goods and luxury goods. Below is a breakdown of the percentages of total household spending on food. Notice that the light blue is food and drink, while the dark blue is alcohol and tobacco- thus the light blue is the important figure here. The United States has some of the lowest spending at roughly 7%, while many other countries still average near 50%. It is incredible to think that in Cameroon, households usually only have 53% of their income to spend on all other goods.
