Third World is a term originally used to distinguish those nations that neither aligned with the West nor with the East during the Cold War.
These countries are also known as the Global South, developing countries, and least developed countries in academic circles.
WHAT İS İT MEAN OF THİRD WORLD COUNTRİES?
Also this term means that the economically underdeveloped countries of South Asia, Sub-Saharan Africa, and Latin America, considered as an entity with common characteristics, such as poverty, high birthrates, and economic dependence on the advance countries
South Asia
Sub-Saharan Africa
Latin America
The underdevelopment of the third world is marked by a number of common traits; distorted and highly dependent economies devoted to producing primary products for the developed world and to provide markets for their finished goods; traditional, rural social structures; high population growth; and widespread poverty.
Urbanisation is the process in which the number of people living in cities increases compared with the number of people living in rural areas. A country is considered to be urbanised when over 50% of its population lives in urban places.
Urbanisation is most rapid in Third World countries, where the world's largest cities occur
The process of urbanization has occurred differently in much of the developing world.
Historically many of these countries were former colonies. They have some of the highest rates of population growth and the largest urban areas. They are characterized as being poor having significantly less technology then the developed world, and a very rapid transition from rural to urban societies.
Population is placing pressure on urban areas and without having the benefit of industrialization the lack of employment opportunities for the mass of urban migrants is undermining the ability of cities to incorporate people.
The consequences of this lack of employment opportunities are growing urban areas a large percent of whose population is unemployed and living in poverty and forced to live in unsanitary squatter settlements(Slum ,Favela, Shantytown )
Slums form at edges of cities, not in the center
No infrastructure is provided (water, utilities, sanitation Pirated electricity
Small formal sector, so large numbers unemployed or, at best, in the informal sector
Squatter settlements = illegally set up settlements on land and do not pay rent.
These places have not sewer, water or electricity
Area of a city characterized by substandard housing and squalor and lacking in tenure security.
Also known as informal settlements found in cities in the developing world.
One billion people worldwide live in slums
Slum can seen mostly in India
Slum in Kolkata, India
Generally used term for a shanty town in Brazil or Mexico
This was the place where former slaves with no land ownership and no options for work lived.
Favela, Mexico City
Shanty towns, which are usually built on the periphery of cities, often do not have proper sanitation, electricity or telephone services.
Shanty towns are mostly found in developing nations
One-sixth of the world's population live in the shanty towns

Involution is capacity of service sector to absorb more and more labor in a finely expressed division of jobs
Two parts: Firm centered or formal and bazaar or informal economy
Firm centered consists of impersonal social institutions, specialized occupations for productive ends and is capital intensive
Bazaar economy consists of independent activities of highly competitive traders who relate to one another through complex
Informal-Bazaar economy is the most absorptive
Consist of carefully managed credit relationships, splitting of risks and sliding prices
Effect is to split trading activities to allow more to enter the system
Process of involution and absorption is characterized by tenacity of basic patterns, internal ornateness and unending virtuosity-special skills
Informal- characterized by small scale, easy entry, adapted technology, flexible hours, no set wages and family or local organization
Formal- large scale, more difficult entry requirements, often imported technology, fixed hours of operation, daily/weekly or monthly wage, distant ownership or management
Contaminated water Inadequate disposal of human wastes Wastewater and garbage Insects, pests (e.g. rats) and parasites in homes Inadequate-sized houses, poor ventilation and
overcrowding Children at risk from traffic, unsafe or contaminated

Traffic Fatalities and Rates, Selected Countries
Low wage jobs – shoe shine, begging, selling souvenirs.
Child labour Huge gaps between rich and
poor. Hard to offer services to public
Schools, transportation systems, social services
Social Problems Squatter settlements - Illegally set
up settlements on land and do not pay rent. Very poor living conditions – no sewers, water or electricity .
Slum Dwellers – pay rent Poor living conditions
High sick rates High Infant mortality Poverty Crime World Bank gives aid to assist in
educating and providing healthcare.
Natural Disasters hit them the hardest because of the poorly constructed buildings.
Sites next to industrial areas are very susceptible to toxins and air pollutants.
Developing countries usually have very poorly maintained vehicles and unregulated gas leading to pollution. (CO, CO2, lead, NO2,)
Infrastructure supplying clean drinking water is usually connected to infrastructure dealing with disposal of waste. (Much of the sewage in poor urban areas still runs
into ditches beside roads and flows into rivers used for drinking.)
3rd World Drinking Water Clean water
3 million people die every year due to waterborne diseases caused by unclean water, 90% are children under the age of 5.
Increase in demand of rural property can cause prices to rise
Young people cannot afford to buy homes in their own village
Newcomers to rural areas may not appreciate the traditional customs of village life
Original inhabitants may feel swamped by new-comers
The people who leave cities to live in rural areas tend to be skilled or be professionals. They are often well educated and earn god salaries.
People who are left behind tend to belong to the lower income groups, less skilled and less educated, and more likely to be unemployed
Due to population decline in urban areas the following may occur:
Funds diminish for transport, education, leisure and other services
Poorer unemployed people remain in the city
