The US Census presents the latest estimates and projections of world population from the U.S. Census Bureau. The world population increased from 3 billion in 1959 to 6 billion by 1999, a doubling that occurred over 40 years. The Census Bureau's latest projections imply that population growth will continue into the 21st century, although more slowly. The world population is projected to grow from 6 billion in 1999 to 9 billion by 2040, an increase of 50 percent is expected to require 41 years.

In addition to growth rates, another way to look at population growth is to consider annual changes in the total population. The annual increase in world population peaked at about 88 million in the late 1980s. The peak occurred then, even though annual growth rates were past their peak in the late 1960s, because the world population was higher in the 1980s than in the 1960s.

'According to ECO, 30% of the world population is undernourished and that mostly concerns Africa, 29% of the population goes through chronic food lack.
