People migrate to urban countries and developed countries in search of better employment , more opportunities , higher level of education and better living . Almost 3% of the world population are not living in the country they were born in. United States has the maximum number of permanent immigrants. Due to immigration it becomes difficult for the countries to maintain the population . Also the population density increases which makes it difficult to handle the country with such a huge population . It is also known that overpopulation is seen in developing countries rather than developed countries due to lack of awareness , no family planning , less education etc. migration created an imbalance in the population density of the overall world. Also it is said that in the next 45 years the population in the richer countries would shrink more and more and that in the poorer countries would increase immensely . some of the reasons are that the population in developing countries consist of a lot of young people from the age of 15 to 30 .So the rate of fertility is very high and gets higher every year . also there is poor education and lack of information and awareness about protection and family planning which adds to increase of births. It is difficult for humans to discuss reproductive control maybe because of shyness . Also many parents are not much open to their children to talk about such things as a result there is lack of information which leads to unplanned fertility
