It may be defined by the number of residents, the population density, the percent of people not depending on agriculture, or the provisions of public utilities and services as education and electricity. Each country has its own standards of a urban area.

Classification of metropolitan includes urban and rural areas
A city's population grows because of natural increase and of inmigration
The growth of urban agglomerations shows population growth in different cites. New York or London are cities in more developed countries which grew during the 1800s and 1900s, and now they are in a slow growth or decline. Some cities in less developed countries, such as Mexico City, grew very rapidly between 1950 and 1980, and now are growing more slowly. Other cities, specially Asian and African ones, are experiencing very rapid growth now and are projected to continue like this.

Growth of urban centers
Through most of history, the human population has lived in rural areas, depending on agriculture and hunting. In 1950, 30% of the world's population resided in urban centers. The world has experienced unprecedented urban growth in recent decades. In 2008 world's population was split between urban and rural areas. Developed nations were about 74% urban, while 44% of residents of less developed countries lived in urban areas. Urbanization is occurring rapidly in many less developed countries. Is expected that 70% of the world's population will be urban by 2050.
Urbanization
1st urban centers
The natural increase is the excess of births over deaths. This is way the population of a city grows.
Inmigration is the amountof people from other places who comes to a city, country,... Emigration is the opposite, the amount of people who go away from a place, city, ...
During the 19th and 20th century, urbanization resulted from and contributed to industrialization. New job opportunities in the cities spurred the mass movement of surplus population away of the countryside. Migrants provided cheap, plentiful labor for the emerging factories.

An example of a megacity
As population increases, more people will live in large cities. Cities with more than 10 million inhabitants are called megacities. In 1975 there were only three megacities around the world, one in a less developed country. In 2000 there were 16 megacities, and in 2025, there are projected to be 27 megacities, 21 in less developed countries.
