Effect on Market Size in terms of Average Income and Demand: A Context Concerning Bangladesh

In a developing country, the income of most people is very low and some people earn a lot more than that. Bangladesh is not out of this rule. It is a very hard task to measure the demands of people due to the rising and falling of income suddenly. It is a very natural fact that the income ups and downs suddenly of a developing country due to the political issues, social issues, and naturals disasters. The average income is calculated according to all this. The size of the market depends on the purchasing power of the people. The greater number of people able to reach a minimum of purchasing power, the market size will increase.
