The given table illustrates annual income per person(in US$), life expectancy at birth, daily calories supply per person and adult literacy rate for four countries measured in 1994 according to United Nations.
Overall, Japan was leading in three out of four metrics, while Canada had the largest calorie supply per person. At the same time, Zaire had the smallest figures in all of the indicators out of four countries. Judging by the indicators, Japan and Canada were the most developed countries, while Peru and Zaire fell behing drasticaly; therefore, they are rather underdeveloped.
Annual income per person varied the most, as Japan had it at $15,760, while Zaire only had $130, being more than a 100-fold difference. Canada had $11,100 per person, which is still much higher than Peru, as it had this metric at $160, still being around a 70-fold difference. Life expectancy varied significantly less, ranging from 47 for Zaire to 78 for Japan, while Peru and Canada had it at 51 and 76 respectively.
Country with a largest daily calorie supply per person was Canada, standing at 3326, while Zaire had the smallest number, being 1749. Japan and Peru had 2864 and 1927 calories respectively. Canada and Japan had the same 99% adult literacy rate, while between them and Peru there was a major 31% gap, as Peru had only 68% literacy rate. At the same time, Zaire fell behind every other country, as its 34% was half of the Peru’s rate.
