6.3 Cities and Globalization

Cities

Louis Wirth, an American sociologist, defined a city as a "permanent settlement of relatively large size, relatively high population density, and relatively diverse population with respect to social and economic status, race, and culture." Wirth's definition of a city is based on three characteristics that distinguish cities from rural areas: large size, high population density, and social stratification and heterogeneity.

According to Wirth, the large size and high population density of cities create a sense of anonymity and impersonality among residents, and the social stratification and heterogeneity of cities create a sense of diversity and complexity. These characteristics of cities, Wirth argued, have important social and psychological consequences for the people who live in them.

Some examples of cities that may fit the characteristics of Wirth's city could include:

• New York City
• London
• Tokyo
• Hong Kong
• Singapore

Wirth's definition of a city has been influential in the field of sociology and has shaped the way that scholars and policymakers have thought about the nature and function of cities. It has also been subject to criticism and revision by subsequent scholars, who have pointed out that it is based on a narrow and Western conception of cities and that it does not adequately capture the complexity and diversity of urban life in other parts of the world.

Importance Of Cities in Different Sizes

Cities of different sizes can play important roles in regional, national, and global economies and societies.

Mega cities, or cities with a population of over 10 million people, are often major economic, political, and cultural centers, and are centers of innovation and creativity. They can be engines of economic growth and development, and can provide a wide range of amenities and services for their residents. However, mega cities can also face challenges such as pollution, inequality, and the negative impacts of globalization.

Large cities, or cities with a population of over 1 million people, can also be major economic, political, and cultural centers, and can provide a wide range of amenities and services for their residents. They can also be hubs of innovation and creativity, and can play a key role in regional and national economies.

Small cities, or cities with a population of less than 1 million people, can also play important roles in regional and national economies and can provide a high quality of life for their residents. They can be centers of innovation and creativity, and can provide a range of amenities and services, such as healthcare, education, and cultural activities.

Regardless of their size, cities can be important centers of economic, social, and cultural activity, and can provide a range of benefits to their residents and to the wider region or country in which they are located.

The urban hierarchy of cities refers to the classification of cities based on their size and importance. At the bottom of the hierarchy are the smallest settlements, such as hamlets and villages, which are often rural and have a small population. Above these are towns, which are typically larger than hamlets and villages and may have more developed infrastructure and a larger population. Cities are even larger and more developed, with a population of at least 100,000 and a more diverse range of industries and occupations.

A metropolis is a large city or urban area that is the economic, cultural, and political center of a region. A megalopolis is an even larger urban area, typically consisting of multiple cities and their surrounding suburbs that have grown together to form a continuous urban region. New York City is an example of a megalopolis, as it is made up of five boroughs and has a population of over 18 million people in its metropolitan area.

New York City, London, and Tokyo are often considered to be the three main world cities, based on their economic, cultural, and political importance on a global scale. These cities are often referred to as "global cities" or "world cities," and are characterized by their high levels of economic activity, cultural influence, and connectivity to other global cities.

Other cities are often rated and ranked based on their economic, cultural, and political importance to the areas they serve, and are classified on a scale such as the Alpha, Beta, and Gamma scale. The Alpha scale is used to rank the most important global cities, while the Beta and Gamma scales are used to rank cities of increasing lower importance.

The Alpha scale includes cities such as New York City, London, and Tokyo, as well as other cities such as Paris, Hong Kong, and Singapore. The Beta scale includes cities such as Amsterdam, Barcelona, and Chicago, while the Gamma scale includes cities such as Adelaide, Bangalore, and Boston.

These scales are based on a variety of factors, such as the size and complexity of the city's economy, the level of cultural and political influence, and the extent of connectivity to other global cities. They are used to help understand the relative importance of cities in the global economy and to inform policy and investment decisions.
