Increasing Homogeneity

 
Watch as the food supplies in countries around the world become more similar over the past five decades. Each dot represents a country’s average per capita food supply in a given decade, including both the number and the relative abundance/evenness of the crops and animal products that contribute to calories, protein, fat, and food weight. The farther apart dots are, the more the countries’ food supplies differ, with countries at the edges varying most from the global average diet (center).
 
View all countries or select countries of interest, select a measurement and scroll through decades using the slider. Check the “Show history” box to track change across decades.
