Trends in population, developed and developing countries, 1750-2050 (estimates and projections)
Click here, or on the graphic, for full resolution. Trends in population, developed and developing countries, 1750-2050 (estimates and projections). Each day 200,000 more people are added to the world food demand.
The world’s human population has increased near fourfold in the
past 100 years (UN population Division, 2007); it is projected to increase
from 6.7 billion (2006) to 9.2 billion by 2050, as shown in
Figure 4 (UN Population Division, 2007). 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 (UN Population
Division, 2007). 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 (annual growth of 2.4%
versus 1.4% in Asia, compared to the global average of 1.3% and only
0.3% in many industrialized countries) (UN Population Division,
2007). In sub-Saharan Africa, the population is projected to increase
from about 770 million to nearly 1.7 billion by 2050.
