Suppose records show that the average income in a country has been increasing over a period of time. From this, can we conclude that all sections of the economy have become better? Illustrate your answer with an example.

If records show that the average income in a country has been increasing over a period of time. As we know that average income of a country is a way to determine the development of a country but it does not guarantee the progress of the economy. Few examples have been seen in which clearly it was shown that there are many other factors which are important for the overall development of a particular society. Some factors are infant mortality rate and literacy rate etc.
