Availability of food across countries
Food is a basic human need. And we tried to estimate how much people pay for food in different countries. In general, price of 1000 Kcal goes up inline with per capita income. For example, in Greece, Belarus, Croatia, Japan and Macedonia people pay $2.8 (based on PPP) for 1000 Kcal. At the same time in Nigeria, Uzbekistan, China India and Kenya the price of 1000 kcal is less then $0.7. It is interesting, that the U.S. citizens pay for food noticeably less compared to other developed and many developing countries.
