The main reason for overpopulation is the increased birth rate and decreased death rate. So that there is only 2 methods to lower the growth rate, decrease births or increase deaths. Because growth centralizes around ideas of improving superiority of life, and thus life is a central idea to development, advocating a strategy of causing death seems differing to the spirit of the project. So the viable option is lowering birth rates.India’s growth rate has noticeably enhanced over the past years, reducing from 2.2 in the 1980s to 1.47 in 2003. It remains over the world average of 1.33. A constant population (zero growth) by the year 2045 is the aim of India’s National Population Commission, but some call into question whether or not this is sufficient.There are diverse reasons for high birth rates; religious reasons, ignorance, attempts to ensure reproductive success, attempts to create a family labor pool—the list continues. But the measures being measured should not engage draconian laws aimed only at results which overlook the rights and potential usefulness of the people.Immigration is also a reason for increased population rate. If the inhabitants of different countries migrate to a particular part of the world and stay over there, the area is bound to suffer from the ill effects of overpopulation. If the rates of emigration from a certain nation do not match the rates of immigration to that country, overpopulation makes its way. Crowding of immigrants in certain parts of the world, results in an imbalance in the density of population.Higher population rate inversely affect each and every person.  Food, cloth, shelter etc are the important factor for a person. Overpopulation may cause problems like food shortage, shelter shortage problems etc. The main reason for the increased number of http://www.offlineproperty.com/Cochin-Flat.html - - flats in Cochin is the shelter problem due to overpopulation.
