The rapid growth of population has posed many socio-economic problems in different countries. The main problems are:

1. Food problem: Growth of the population has led to shortage of foodgrains in many areas. Agricultural production has increased due to new technology, yet many countries have to import agricultural products.
2. Housing problem: Housing conditions are poor in over-populated countries. People live in slum areas. Skyscrapers are being built in many Metropolitan towns.
3. Unemployment: Rapid increase in population leads to unemployment. Migration of people from over-populated rural areas has added to Unemployment.
4. Low standard of living: Per capita income is low in overcrowded areas so living conditions are poor. People do not afford to have basic necessities of life. Population explosion leads to poverty and a poor standard of living.
5. Dependent population: A large percentage of young people become dependent on a small working population.
6. Social problems: Many social problems arise due to overcrowding. Poor health and bad sanitary conditions lead to epidemics.
