The given table illustrates data on four social and economic indicators for Canada, Japan, Peru, and Zaire in 1994, as reported by United Nations.
Overall, it is clear that developed countries such as Japan and Canada, performed best across all measures, whereas Peru and Zaire had the lowest scores in every indicator.
In terms of annual income, Japan led with 15,760 US dollars per person, followed by Canada with 11,100. By contrast, people in Peru and Zaire earned only 160 and 130 dollars respectively. Life expectancy showed a similar pattern: Canadians and Japanese lived around 76-78 years on average, whereas Peruvians and citizens of Zaire had much shorter lives, at 51 and 47 years respectively.
Among the four nations, calorie intake and literacy rates also showed clear differences. The biggest gap in calorie intake was between Canada and Zaire, where the figures were 3,326 and 1,749 respectively, while Japan and Peru remained in the middle at 2,846 and 1,927. A similar pattern was seen in literacy, with Japan and Canada reaching 99%, compared to 68% in Peru and 34% in Zaire.
