The world and territory totals are not always given. Why?
All the figures for the world, each region and every territory are available in the data sheet of the data file for each map. The cartograms convey the comprehensible relative proportions: if Angola is twice the size of Zambia then the variable in Angola is twice as large as in Zambia. This comparison between territories can be more informative than the absolute figures, which are frequently unimaginable large numbers (billions of dollars for instance).
