The table presented provides data provided by the United Nations statistics on 4 social indexes: annual income in SUS, life expectancy, daily calorie supply and adult literacy in Canada, Japan, Peru and Zaire in 1994.
Overall, a direct correlation between the annual income per person and such indicators of prosperity as life expectancy, daily calorie supply and adult literacy can be seen in all countries. The only exception was the daily calorie intake of the Japanese, ranking second while its annual income was the highest. Generally, Japan and Canada by far outperformed Peru and Zaire in all indicators.
Japan had the lead in terms of annual income of $15.760 and life expectancy at birth of 78 years, being closely followed by Canada with $11 100 and 76 years respectively.
However, Canadians consumed the highest number of calories per day, being 3326.
Almost all adults living in these countries were literate.
In stark contrast, people living in Peru earned annually only $160 and in Zaire $130
per person. Accordingly, citizens of these countries consumed not more than 1927 calories daily, and had a life expectancy of 51 years in Peru and 47 years in Zaire. Of note, adult literacy rates of these countries were very different as Peru had twice as many literate adults as Zaire (68 and 34 respectively)
