State any two problems each of overpopulation and under population.

Two problems of overpopulation are-

1. Rapid population growth: In most of the under developed countries, population increases rapidly and family planning is not practised on a large scale due to illiteracy and ignorance.

1. Uneven distribution of population: Average population densities for underpopulated countries are low, and in many areas there are practically no people at all.
2. Slow growth of industry: The growth of industry is often slow in underpopulated countries because there is a shortage of labour, especially skilled labour
