Urbanization is a process of moving populations from rural to urban areas. As more people live in cities, their population growth creates new opportunities and challenges.
The Industrial Revolution sparked mass urbanization by creating factory towns where people lived near the factories that they worked in. These are called company towns and included cities like Detroit, Flint and Saginaw Michigan.
Industrial Revolution
The Industrial Revolution caused a shift away from agriculturally based societies to largely urban ones. This shift accelerated as new technologies enabled more efficient production and created jobs that required human labor. This demand for labor led many people to move from rural areas to cities, which became a draw for workers and their families. Urban centers grew due to the number of available jobs, better pay and higher quality of life, which included access to education and healthcare.
The pace of global urbanization has sped up over time and it is expected to continue at this rate for decades to come. By 2050, most countries are projected to have a majority population that lives in urban areas. This map allows users to toggle between high-income, lower-middle and upper-middle income countries to see if the majority of their population lives in urban or rural areas. Users can also use the time slider to view how the world's urbanization rates have changed with time.
Despite this positive change, urbanization brings with it challenges. The most obvious issue is a lack of infrastructure and resources for a growing city population. Urbanization also disproportionately affects low-income individuals, as they often find it difficult to afford housing in the cities where they live. These residents typically reside in slums, which can lead to poor health, overcrowding and exposure to infectious diseases.
Government leaders often find it challenging to manage these issues and provide sufficient services for urban populations. They must ensure that they plan for future growth by addressing issues like housing, transportation and water management. They must also consider devolving power to communities on the ground, including slum areas. This may allow them to make decisions more responsively and develop their own infrastructure.
Natural Population Growth
The world’s population has been growing rapidly and it is predicted that by 2050 over two-thirds of the world’s population will live in cities. This increase is mostly due to migration from rural areas and the high fertility rates associated with these demographics.
As the world’s population continues to grow, it will have a direct impact on the way we live in our cities. Urban growth will cause increased demands on city infrastructures such as road and public transportation, water supply, sewerage, clinics and schools. If this growth is managed wisely, then it will be possible for cities to keep up with the increasing needs of their residents.
However, if this process is not handled properly then it could lead to overcrowding and unsustainable living conditions within the city. In the past, urbanization has usually occurred at a manageable rate in developed countries as these communities are able to adapt to their own growing needs.
In many cases, this adaptation is achieved through the expansion of already existing cities. However, in developing countries this may not be as feasible and urbanization will happen through a different method. This method is known as de-ruralization and it occurs when people from rural areas move to the city center in search of work and education opportunities.
Regardless of how the urban population is created, it has a large ecological footprint on the surrounding landscape. Even small amounts of urbanization can impact stream ecosystems, especially when it involves riparian vegetation removal, channel modification and point or non-point wastewater inputs. These impacts reduce organic matter inputs, physical habitat and water quality in streams. Despite these negative impacts, urbanization has a positive effect on human health and economic development.
Commercialization
The growth of cities and the rapid increase in the number of urban dwellers around the world have had profound economic, environmental, societal and health implications. In many developing countries, unchecked urbanization - with people crowding into slums and overcrowded city centres - goes hand in hand with poverty. The ability of local businesses and government to work together to address these risks largely determines whether cities make the world more resilient or less so in a rapidly changing global economy.
Those who see the positive aspects of urbanization point to the productivity benefits of having business and industries concentrated in the same area. This leads to increased production, as companies can focus on the most efficient ways of doing things, learn from other similar firms, and share research and development. It also means that the cost of transporting goods and services is reduced, as companies are close to customers and suppliers. In addition, the concentration of educated and creative workers in one place supports innovation, which accelerates economic progress.
Urbanization also encourages lower fertility rates, which can lead to the enjoyment of a demographic dividend in which older generations can work and save more money than they would have been able to in rural areas. Finally, the availability of a wide variety of health care and education services are other positive effects of urbanization.
However, despite the benefits that cities can offer society, urbanization can present significant challenges for both businesses and governments. A major problem is the lack of adequate infrastructure, which can be difficult to provide in large cities. The solution lies in devolving more power to local authorities, so that business leaders and local communities can help to develop the right infrastructure for their city.
Infrastructure Development
The growth of cities brings with it a variety of infrastructure. Infrastructure is both soft and hard, but it provides the foundation for a city’s economy and quality of life. Examples of soft infrastructure include schools, hospitals and public support services, such as libraries and cultural institutions. Hard infrastructure includes utilities, such as water distribution and power generation, transportation networks and communication systems. Other infrastructure includes financial, such as banks and markets, as well as social and environmental infrastructure, including recreational facilities, parks and public space.
With the right planning, these infrastructure developments can help to mitigate health and environmental problems associated with urbanization. But to do so, it is important that the decision making process around these projects devolves down to a local level, with municipalities and district authorities, as well as communities in slum areas, being given a voice in this matter.
Many people see the attainment of a 50 percent urban global population as a positive development, with some citing its upsides, which include increased average incomes and healthier living conditions. However, critics have a number of concerns about the issue, such as the pressure on rural populations to migrate to urban areas and the increase in inequality, as seen in the development of slums.
In addition, rapid urbanization can lead to unsustainable land consumption and exacerbate existing ecological issues, such as pollution, waste management and climate change. A solution here may be to implement a green urbanization strategy, with sustainable infrastructure and the integration of a range of sustainable technologies. This requires a strong partnership between the private and public sectors and must be accompanied by a policy of devolution of power to lower levels of government.
Socio-Economic Divide
The growth of cities is a massive global phenomenon. It has led to a great deal of social, economic and environmental change. But it is also creating enormous risks, especially in poor countries that are undergoing rapid urbanization. Cities are centers for technological innovation and economic development, but they are also home to high concentrations of poverty, inequality and a growing spread of communicable diseases.
Across most rich countries, including most of Western Europe, the Americas, Japan and Australia, more than half the population lives in large cities. In many lower to middle income countries, that number is even higher. This is despite the fact that, on average, rural areas have better quality of life than their urban counterparts.
There are a variety of reasons why this is the case. One reason is that wealthier people tend to live in more desirable neighborhoods within cities, often closer to jobs and transit. This makes sense as they can afford to pay more for the convenience of living in these areas. But, this means that those in the bottom tier of the socio-economic ladder are left further out from the center and have a more difficult time finding affordable housing close to their job.
This leads to the other major problem associated with urbanization: inequality. It is not uncommon for a city to have higher inequality levels than its country as a whole, particularly if it has a large amount of low-income residents. This can be because of a range of issues, from poor access to education to the prevalence of crime and pollution. However, it can also be because the benefits of technology are not being distributed evenly.
