The table presents data on four welfare indicators: annual income per person (in $US), life expectancy at birth, daily calorie supply per person, and adult literacy. The information is provided for 2 developed countries and 2 developing countries in 1994 by the United Nations.
Overall, Canada and Japan had higher results in all four indicators, showing their strength over developing countries, namely Peru and Zaire. Moreover, there is a direct relationship between income and other indicators of wealth.
Canada had the lead in daily calorie intake despite being outperformed by Japan in terms of annual income level. While their calorie consumption difference is roughly 500 calories, the earning amount was 15760 for Japan and 11100 for Canada, respectively. Japan had a life expectancy at birth of 78 years, followed by Canada at 76 years per person, and almost all adults in these countries were literate.
In stark contrast, citizens of Peru earned $160 annually and Zaire’s $130 only, which is much less than in the previous two countries. Similarly, their daily calorie consumption was between 1700 and 2000. One notable thing is that the adult literacy rate of Peru was exactly double that of Zaire: 34% in the latter and 68% in the former.
