The percentage of the population living in city areas is growing significantly. The leading reason may be the opportunities that rural areas do not offer, but cities do. It may result into overpopulation in the city areas.
The main reason of living in urban areas is the opportunities. Cities may offer a more advanced healthcare, higher-paying jobs, and better education . In many countries, top-tier universities and schools are located in major cities. So, families may move from the rural area to a city in order to provide better education for their children. For instance, in Uzbekistan most of the universities and the best schools are located in Tashkent, which is the capital city. Furthermore, most of the offices, business centers and places that offer high-paying jobs operate in cities. People may move to cities to earn more money and work for big companies. Health care is also a major factor, due to the concentration of the best healthcare services in big cities, some individuals move in cities to get treatment from the best professionals in the country.
Nevertheless, such movement towards urbanization leads to overpopulation in the urban areas. Due to the high concentration of people in cities, the air quality is relatively worse, moreover, most of the city residents travel by private vehicles, rather than public transport, which is also a reason for the air pollution. Furthermore, overurbanization causes noise pollution along with overcrowding. For instance, in Tokyo the streets are often overcrowded with people, due to the population of the city.
In conclusion, city provides various opportunities such as high salary, better healthcare and better education. As the result, overurbanization may occur, which can cause air contamination, noise pollution and overcrowding.
