How diverse are countries’ modern day food supplies? Each dot marks the estimated diversity level of each country’s current (2009 to 2011 average) national per capita food supply. Diversity is measured in terms of the total number of contributing crops in each country, and by two common diversity metrics (Shannon’s and Simpson’s) that account not only for the total number of crops, but also the relative abundance/evenness of each crop commodity contributing to the food supply (the more evenly all crops contribute, the more diverse the diet is considered to be). Countries are listed from most diverse to least.
Select a diversity index, and hover or click on calories, protein, fat, or food weight to filter for that measurement. Also view countries on the map and see the lists of most and least diverse countries in the tables.
