Origins and historical transformation

Cities support regional trade

3700 BC - 1700

Before industrialization, urban economic activity was concentrated mainly in market exchange and small-scale manufacturing. Towns served as commercial centers within predominantly agricultural societies.

Early urban civilizations emerge

3700 BC

The earliest cities developed in the Indus Valley Civilization, Mesopotamia, and Egypt. These settlements formed the first major urban centers, while most people continued to live in rural communities engaged in subsistence agriculture.

Urban–rural equilibrium continues

3700 BC - 1700

From the emergence of the earliest cities until the eighteenth century, most people lived in rural agricultural communities while comparatively small towns supported markets, trade, and limited manufacturing.

Urban development is mapped across history

3700 BC - 2000

Yale University later published urbanization data covering the period from 3700 BC to 2000 AD. The data were used to visualize the development of cities around the world over thousands of years.

Industrial-era urban growth

British Agricultural Revolution begins

1700 - 1800

The British Agricultural Revolution helped transform production and rural society before and during the late eighteenth century. Alongside industrialization, it contributed to the breakdown of the older urban–rural equilibrium.

Industrial Revolution begins

1760 - 1840

The Industrial Revolution, beginning in the late eighteenth century, fundamentally changed the relationship between countryside and city. Expanding industry created urban employment and accelerated the movement of people into towns.

Urban–rural equilibrium breaks

1780 - 1800

The combined onset of the British Agricultural Revolution and Industrial Revolution finally disrupted the long-standing balance between predominantly rural populations and small urban centers.

Nineteenth-century urban population growth

1801 - 1900

Urban populations grew at unprecedented rates during the nineteenth century. Growth resulted both from continued migration from the countryside and from major demographic expansion.

England and Wales urban share reaches 17%

1801

In 1801, 17% of the population of England and Wales lived in cities with more than 20,000 people, providing an early benchmark for industrial-era urbanization.

England and Wales urban share reaches 54%

1891

By 1891, the proportion of England and Wales living in cities with more than 20,000 people had risen to 54%, illustrating the scale of nineteenth-century urban growth.

United States reaches 28% urbanization

1891

Under the broader definition cited for the period, the United States had an urbanized population equal to 28% of its total population in 1891.

Prussia reaches 41% urbanization

1891

Under the broader definition cited for the period, 41% of the population of Prussia was urbanized in 1891.

France reaches 37% urbanization

1891

Under the broader definition cited for the period, France had an urbanized population equal to 37% of its total population in 1891.

England and Wales reach 72% urbanization

1891

Using a broader definition of urbanization, 72% of the population of England and Wales was urbanized in 1891.

Urban class segregation is described

1962

Eric Hobsbawm’s The Age of Revolution: 1789–1848, first published in 1962, described nineteenth-century urban development as a vast process of class segregation that pushed newly industrial laboring poor into impoverished areas outside central government, business, and bourgeois residential districts.

The Age of Revolution is republished

2005

A 2005 edition of Eric Hobsbawm’s The Age of Revolution: 1789–1848 preserved and renewed attention to the book’s account of urban class segregation during the period of industrial transformation.

Modern urbanization trends

World urban population reaches 15%

1900

At the turn of the twentieth century, approximately 15% of the world’s population lived in cities, showing that global urbanization was still limited despite rapid industrial-era growth in some countries.

New urban forms receive multiple names

1991 - 2000

New metropolitan forms have been described with terms including edge city, network city, postmodern city, and exurb. These labels reflect increasingly dispersed and interconnected patterns of urban development.

Urban expansion accelerates globally

1992 - 2015

Globally, urban areas more than doubled in size between 1992 and 2015, expanding from 33 million hectares to 71 million hectares.

The global urban population majority is reached

2007

The United Nations identified 2007 as a turning point: for the first time in human history, more than half of the world’s population lived in cities.

Re-urbanization emerges in the United States

2011

Beginning in 2011, the United States experienced re-urbanization as suburban flight was associated with chronically high transport costs, reversing an earlier pattern of movement away from cities.

Urban areas reach 71 million hectares

2015

By 2015, global urban areas covered approximately 71 million hectares, up from 33 million hectares in 1992.

Urbanization data visualization is published

Jun 2016

In June 2016, Yale University published urbanization data spanning 3700 BC to 2000 AD. The data supported a video showing the historical development of cities around the world.

Urbanization reaches 56.2% globally

2020

The global urbanization average reached 56.2% in 2020, and most countries in the world were classified as urbanized.

Urbanization reaches high rates across major countries

2022

As of 2022, urbanization rates exceeded 80% in the United States, Canada, Mexico, Brazil, Argentina, Chile, Japan, Australia, the United Kingdom, France, Finland, Denmark, Israel, Spain, and South Korea.

Urbanization impacts and projections

Doha land-surface temperatures rise

2002 - 2023

A Qatar University study reported that land-surface temperatures in Doha increased annually by 0.65 °C from 2002 to 2013 and 2023, linking urban development with significant local heat changes.

Urbanization and depression are associated in Sweden

2004

A 2004 study of 4.4 million Swedish residents found that people living in cities had a 20% increased chance of developing depression.

Urban flood risks are illustrated in Jakarta

2007

The 2007 Jakarta flood was cited as another example of urban vulnerability to flooding and the environmental pressures accompanying city growth.

Stewart Brand argues urbanization benefits nature

2009

In his 2009 book Whole Earth Discipline, Stewart Brand argued that the effects of urbanization are primarily positive for the environment.

Urban flood risks are illustrated in Thailand

2011

The 2011 Thailand floods were cited as an example of hazards associated with urbanization and environmental change affecting cities and surrounding regions.

The United Nations projects food pressure

Jul 2013

In July 2013, a United Nations Department of Economic and Social Affairs report warned that 2.4 billion additional people by 2050 would require food production to increase by 70%, placing pressure on food resources, especially in countries already facing insecurity.

Key Facts

  1. The earliest known cities emerged in Mesopotamia around 3500 BCE, supported by agriculture, trade, government, and organized religion.
  2. Ancient urban centers such as Ur, Mohenjo-daro, Athens, Rome, and Teotihuacan developed systems of administration, infrastructure, and social organization.
  3. The Industrial Revolution accelerated urbanization during the eighteenth and nineteenth centuries as factories attracted workers to expanding cities.
  4. Rapid nineteenth-century urban growth led to major challenges, including overcrowding, pollution, poor sanitation, and infectious diseases, prompting modern public-health reforms.
