According to the United Nations' Department of Economic and Social Affairs, about 55% of the world’s population, or 4.2 billion people live in cities. The figure is expected to jump to 68% by 2050 due to the increased rate of urbanization.
A large population prefers urban centers and cities because of modern infrastructure, better economic, and improved health care. Although Latin America, North America, and the Caribbean are some of the most urbanized regions of the world, Asian cities have recorded outstanding population growth. Most of the largest cities in the world such as Chongqing, Shanghai, Beijing, Dhaka, Tokyo, and Karachi are situated in Asia.

What is City Proper?
City proper is a basic concept used to define an urban area and population (other basic concepts are metropolitan area and urban agglomeration). It can be defined as an area within the city limit or boundary. The UN’s World Urbanization Prospect defines the population of a city proper as people living within an administrative boundary of a city or under the jurisdiction of a single political authority. However, the term city proper has been a cause of recurring controversy since some countries have very wide or very narrow city limits.
