Trends in population growth in Developing World
• The world’s human population has increased nearly fourfold in the past 100 years
• Each day 200,000 more people are added to the world food demand
• It is projected to increase from 6.7 billion (2006) to 9.2 billion by 2050
– It took only 12 years for the last billion to be added, a net increase of nearly 230,000 new people each day, who will need housing, food and other natural resources
•
The largest population increase is projected to occur in Asia, particularly in China, India and Southeast Asia, accounting for about 60% and more of the world’s population by 2050
• The rate of population growth, however, is still relatively high in Central America, and highest in Central and part of Western Africa. – In relative numbers, Africa will experience the most rapid growth, over 70% faster than in Asia
– In sub‐Saharan Africa, the population is projected to increase from about 770 million to nearly 1.7 billion by 2050

What is the cause of such population growth in Developing World?
• Intensified globalization
– Resulting in rapid urban‐industrial capitalism
– Clustering of producers and consumers results in urban agglomeration economies
– This process leads to greater productivity and technological innovation
– Thus, resulting in a snowball effect that stimulates urban industrial expansion
– While there are many positives, the negatives spill over creating societal challenges and environmental consequences
Population Pyramids
• A population pyramid is a graphical illustration that shows the distribution of various age groups in a population – also called age‐sex pyramid Males
• It typically represents a country or region of the world, and normally forms the shape of a pyramid

Expansive Pyramid
• A steady upwards narrowing shows that more people die at each higher age band
• This type of pyramid indicates a population in which there is a:
– high birth rate
– high death rate
– short life expectancy • This is the pattern of a economically developing country
Stationary Pyramid
• A population pyramid showing an unchanging pattern of fertility and mortality

Constrictive Pyramid
• A population pyramid showing lower numbers or percentages of younger people
• The country will have a graying population which means that people are generally older
