In fact, in underdeveloped countries, the number of job seekers is expanding so fast that despite all efforts towards planned development, it has not been possible to provide employment to all.
Their income, as a consequence, is reduced and their capacity to save is diminished which, in turn, adversely affects capital formation.
There has been an increase in the number of slums, overcrowded houses, traffic congestion etc. Thus, we can conclude that labour force increases with the increase in population.
Rapid Population Growth creates Food Problem: Increased population means more mouths to feed which, in turn, creates pressure upon available stock of food. Overpopulation can only be solved by spreading awareness of and implementing measures like birth control and access to birth control devices.
This is the reason, the under-developed countries with rapid growing population are generally faced with a problem of food shortage. The above causes are interrelated to the various social issues in our country which are leading to over population.
Unemployment, underemployment and disguised employment are common features in these countries. In order to achieve a given rate of increase in per capita income, larger investment is needed.
