Urbanization is a trend unique to the past few centuries. People tend to migrate from rural to urban areas as they become richer. Living standards tend to be higher in urban areas. All our charts on Urbanization Access to electricity, urban vs. Employment in agriculture vs. Urbanization across the world today. More than 4 billion people — more than half of the world — live in urban areas. How many people live in urban areas today?
Click to open interactive version. How does the share of people living in urban areas vary between countries? In the map shown here we see the share of the population that is urbanized across the world.
How urban is the world? What we know about urban populations and why it matters. How is an urban area defined? Sweden Built-up areas with inhabitants or more and where houses are at most metres apart. Japan Cities defined as shi. In general, shi refers to a municipality that satisfies the following conditions: 1 50, inhabitants or more; 2 60 per cent or more of the houses located in the main built-up areas; 3 60 per cent or more of the population including their dependents engaged in manufacturing, trade or other urban type of business.
India Statutory places with a municipality, corporation, cantonment board or notified town area committee and places satisfying all of the following three criteria: 1 5, inhabitants or more; 2 at least 75 per cent of male working population engaged in non-agricultural pursuits; and 3 at least inhabitants per square kilometre. Zimbabwe Places officially designated as urban, as well as places with 2, inhabitants or more whose population resides in a compact settlement pattern and where more than 50 per cent of the employed persons are engaged in non-agricultural occupations.
Singapore Entire population. Uruguay Cities officially designated as such. The European Commission applied a universal definition of settlements across all countries: Urban centre : must have a minimum of 50, inhabitants plus a population density of at least people per square kilometre km 2 or density of build-up area greater than 50 percent.
Urban cluster : must have a minimum of 5, inhabitants plus a population density of at least people per square kilometre km 2. Rural : fewer than 5, inhabitants. Will we ever reach a consensus on urban population?
This may, at least, bring us one step closer to agreement on how urban the world really is. Urban slum populations. Just under 1-in-3 urban dwellers live in slum households. From to , for example, the share of the urban population in slum households fell from: 44 to 25 percent in China; 55 to 24 percent in India; 37 to 22 percent in Brazil; 77 to 50 percent in Nigeria. Urban density. Urban agglomerations. Population in largest city.
City populations. Population of the capital city. Across the world the most common capital size was in the range of 1 to 5 million people. Population of cities. Long-run history of urbanization. Migration to towns and cities is very recent — mostly limited to the past years. How has urbanization changed over longer timescales — over the past years? Future urbanization. By , more than two-thirds of the world will live in urban areas.
By , close to 7 billion people are projected to live in urban areas. How do living standards change as people move to urban areas? Some examples include: in nearly all countries electricity access is higher in urban areas than in rural areas; access to improved sanitation is higher in urban areas; access to improved drinking water is higher in urban areas; access to clean fuels for cooking and heating is higher in urban areas; child malnutrition is lower in urban settings.
UN-HABITAT defines a slum household as a group of individuals living under the same roof in an urban area who lack one or more of the following 23 : 1. Durable housing of a permanent nature that protects against extreme climate conditions. Sufficient living space which means not more than three people sharing the same room.
Easy access to safe water in sufficient amounts at an affordable price. Sometimes a fifth criteria is included: 5. Security of tenure that prevents forced evictions. It usually incorporates the population in a city or town plus that in the suburban areas lying outside of, but being adjacent to, the city boundaries.
Whenever possible, data classified according to the concept of urban agglomeration are used. However, some countries do not produce data according to the concept of urban agglomeration but use instead that of metropolitan area or city proper. If possible, such data are adjusted to conform to the concept urban agglomeration. When sufficient information is not available to permit such an adjustment, data based on the concept of city proper or metropolitan area are used.

The development of human civilizations was supported by large numbers of people who lived in sparsely-populated rural areas defined by agriculture, fishing, and trade. Over time, as these rural populations grew, cities began to develop.
Urban areas are defined by dense populations, the construction of multiple and often large buildings, monuments and other structures, and greater economic dependence on trade rather than agriculture or fishing. Even the ancient Incan, Egyptian, or Chinese civilizations, changed their environment in order to urbanize. Modern urban cities like New York City, Beijing, Dubai, and Paris are bustling centers of business, entertainment, and trade. However, the modifications humans make to their surroundings in order to urbanize such places can impact the environment in negative ways: pollution, disruption of water flow, deforestation, and desertification.
Explore the effects of urbanization on the environment and help students explore how human cities impact the world around us with this curated collection of resources. This set of classroom ideas addresses worldwide urban growth and how to plan for it.
Throughout history, people have been attracted to cities as centers of culture, learning, and economic opportunity. But urbanization also has costs, especially when it happens rapidly.

In Lebanon , interventions to release tensions reached , people within a year — three times the initial target — particularly those in the host communities close to refugee camps, and also improved service delivery to more than one million Lebanese people.
The city governments are developing and implementing medium-term, integrated development and asset management plans with evidence-based prioritization for municipal infrastructure and services, resulting in increased revenue collection and reduced expenditures, providing financial headroom. Automated systems for public access to information and grievance redressal, as well as updated websites with information on budgets and procurements, are ensuring greater accountability.

Last Updated: Apr 20, Specifically, the Bank adopt integrated approaches to transform the fundamental systems of cities, focusing on four priorities as follows: 1.
Enhance Planning System and Local Capacity The first key strategy is to help cities strengthen their planning systems and local capacities to better design, plan, and manage city assets and urban environments. Strengthen Fiscal and Financing Systems The second strategy aims to maximize multiple financial resources for cities through enhancing fiscal and financial systems. Promote Territorial and Spatial Development The third key element is to promote territorial development in developing countries and cities.
Build Climate Smart and Urban resilience The last key strategy is to build resilience to disasters and climate change.
Research and analytical services Understanding urbanization at different scales: The World Bank is conducting a rich set of research on sustainable urban development. Beyond its huge health impacts, there are significant economic losses to households, firms, and governments as well as large-scale disruptions to lives and livelihoods as a result of lockdowns, disruption of supply chains, and a steep drop-off in commercial activity as a result of COVID This is because prevention and preparedness make economic sense, from strengthening infrastructure and other risk reduction efforts to developing policies and programs that help safeguard the poorest and most vulnerable against disaster impacts.
Innovative instruments such as our Development Policy Financing with Catastrophic Draw Down Option Cat DDO where, if a disaster due to a pandemic or extreme weather event strikes, countries that had previously prepared and approved a Cat-DDO would have quick access — less than 48 hours — to financing for emergency response. The CAT-DDO is a financing instrument that acts a little like a parametric catastrophe bond, in that they provide a source of capital contingent on a disaster being declared in the beneficiary country.
They are similar to an insurance or reinsurance policy, or a catastrophe bond, except that once triggered the contingent financing facility opens up a loan, or line of credit, to the World Bank.
Financing the New Urban Agenda The World Bank helps cities and national governments put in place the financial framework to attract investment and grow in a sustainable manner.
These characteristics include but are not limited to :. Urbanization and Biotic Integrity Numerous studies have examined relationships between land use variables and stream biota. Biotic responses associated with these land use variables include but are not limited to : ALGAE Increased abundance or biomass [Roy et al.
Catchment vs. Riparian Urbanization Where urbanization occurs in the watershed can affect its influence on stream ecosystems. Studies examining land use variables and stream characteristics typically consider land use at one or more of three general spatial scales:. King et al. They found that where development occurs can significantly influence its effects on benthic biota:. Stressor Identification Vol 2.
