It turns out that Google searches for the cost of something vary widely depending on the country of interest. For example, people are most interested in the cost of a passport or a patent in North America. As for Europe, many are concerned about practical things like the cost of living, studying, or buying a beer.
Google users are interested in basic necessities such as food, livestock, and fuel in Africa. But if you look closely, you will find some more controversial search results, such as prostitution in Brazil, Ukraine, Hong Kong, and Latvia; slaves in Mauritania; a kidney in Iran; in vitro fertilization in Australia; and rhinoplasty in Korea.
