Urbanism

In the fifties, the number of population in developed countries was over 155 millions i.e., more than the number of population in developing countries .

In the seventies, the difference has become only 30.000.000 since that date. The developing countries have witnessed migration waves that were not preceded from the rural areas to cities. As a result, the number of population (has increased five or six times).

By the end of the past century, about half a million of world population lived in an urbanized environment and number of population in cities increased to 9.1 billion i.e., double the number of the developed countries. At the same time, the rural population which was almost 3.000.000.000 persons continued their migration to big cities.

Economists and socialists have cared long time ago for the perfect size of cities .

Some experts see that the perfect maximum limit of population should be 500.000 in regard to jobs. When the number reaches 2.000.000 inhabitants, the general standard of living becomes more difficult.

However, these estimations are on average and it is clear that it is impossible to specify an applicable perfect size for each city in the world. It is better to set a goal which is to achieve reasonable averages of urbanization along with medium growth and limited development for big cities. The crisis of urbanization and its social, technical, and economic problems impede the economic progress in the third world countries .

In short, rural development must be part of national development in the course of close cooperation between local communities and general authorities .

Accordingly, one has to exert efforts to decrease the focus on infrastructure, economic activities, and services in cities and capitals to create medium industrial areas to absorb the work power in the country .

We have to learn and train rural people if we want to decrease employment and the huge difference in income levels, as they are the most important reasons of abandoning the country, and increasing the populations in cities .
