ABSTRACT
The concept of demographic transition, which is as old as the human history, tells us that throughout the process of world evolution, human beings are relocating according to the circumstances that they need to day rather than live in a fixed place. As we look at the fertility control and demographic transition in developing and developed countries we can say that in developed countries fertility control strategies have been started before in developing countries, so fertility rates in developing countries are higher than developed countries. All in all, developing countries have problems on demographic transition and of course economic growth which is effected by demographic transition. Fertility rate is high on low-income countries and parents have not enough money to cover needing of their children, so labor force is high in these countries. Unemployment rates are high and because of highness of labor force can be employed in low wages. This situation has negative impact on labor market and economic performance, so educated and young people have to work in bad conditions with low wages. Mortality rates are high in these countries because of insufficiency of public health services that are provided by the state. Nonlinear dynamics in life is also available 148for countries as living systems, so any unexpected input like mass migration or mass deaths due to war or terrorist attacks affect the order of the system. Quality of life and high life conditions are more humane in developed countries, so all countries should complete the demographic transition period to live in more humane conditions. At this point, we wonder that dealing with chaos in that country is related to economic growth of that country or what? Are demographic transition and economic growth triggering each other?
