• It is derived from the Latin ‘Urbs’ a term used by the Romans to a city. • spatial concentration of people whose lives are organized around non- agricultural activities. • Placed-based characteristic that incorporates elements of population density, social and economic organization, and the transformation of the natural environment into a built environment.
• An increase, as in size, number, value, or strength; extension or expansion.
• The (relative or absolute) increase in the number of people who live in towns and cities. The pace of urban population growth depends on the natural increase of the urban population and the population gained by urban areas through both net rural-urban migration and the reclassification of rural settlements into cities and towns.
• 79% of Americans and 50% of the world’s people live in urban areas.
• refers to people living in urban areas as defined by national statistical offices
TWO WAYS of URBAN GROWTH
• Natural Increase
• more births than deaths
• mostly from urban areas
• in search of:
• Educational opportunity
• Better health care
• Freedom from religious, racial, and political conflicts
• Factors Pushed People from Rural to Urban:
• Limited land for growing food
• Declining agricultural jobs
FOUR MAJOR TRENDS OF URBAN GROWTH
• The proportion of the global population living in urban areas is increasing. • The number and sizes of large urban areas is mushrooming. • Urban growth is much slower in developed countries than in developing countries. • Poverty is becoming increasingly urbanized, mostly in developing countries.
1. The Proportion of the Global Population Living in Urban Areas is Increasing. • Between 1850 and 2009, the percentage of people living in urban areas increased from 2% to 50% and could reach 60% by 2030. • About 88% of this growth will occur in already overcrowded and stressed cities in developing countries.
2. The Number and Sizes of Large Urban Areas is Mushrooming.
• 1 M people are added to the world’s urban areas each week.
• 400 urban areas have 1 million people or more
• 18 megacities with 10 million or more people each
• hypercities with 35 million people
• Greater Tokyo, Japan
• But according to UN projections by 2015,
• Mumbai in India
• Lagos in Nigeria
• Dakar in Bangladesh
• Sao Paulo in Brazil
3. Urban Growth is much slower in Developed Countries than in Developing Countries. • Developed countries, now with 75% urbanization, are projected to reach 81% urbanization by 2030.
4. Poverty is Becoming Increasingly Urbanized, Mostly in Developing Countries • The UN estimates at least 1 billion people in developing countries live in crowded and unsanitary slums and shantytowns within 30 years this number will double.
