Population trends --Looking out to the year 2025

About 8,700 people every hour, 146 people every minute, and 2.5 people every second are being added to the global population…
The key theme in population growth is stratification. In effect, many of the populations of developed countries will actually be smaller in 2025 than they are today. Over the same period, the developing world will experience an enormous youth bulge. Reconciling these two demographic movements is the primary challenge of the revolution in population.
The World Population: Currently at 6.30 billion, the total world population will grow by almost two billion by 2025. Eighty percent of the world's population will be in countries least capable of supporting further population growth.
Rate of Population Growth: The rate of population growth (i.e., the ratio of total increase in population each year to the mean population) has decreased drastically since the 1960s. It will continue to fall. By 2025, the world population will likely be growing less than 1% annually. According to the latest estimates from the United Nations, the global population could stabilize in the year 2100 at about 11 billion people.
Global Generation Gap: The population of the developed world is contracting. At least 33 countries across the world are expected to be substantially smaller than they are today. Populations in these developed countries are also getting old--and in the case of Germany and Japan and a few others, very old. In stark contrast, a number of developing countries will have very young populations that their economies may not be able to support.
Hyper-Urbanization: Another huge problem facing us is "hyper-urbanization." By 2025, the portion of the world's population living in urban areas will constitute nearly 60% of the total world population. Already, up to one-half of the populations in the largest cities in the developing world is living in unplanned and illegal squatter colonies that are highly vulnerable to disease and natural disasters.

Due to the combination of a high mortality rate and low birthrate, Russia is depopulating at the rate of 2225 people a day...

Eight countries--Bangladesh, China, India, Nigeria, Pakistan, the United States, Ethiopia, and the Democratic Republic of Congo --will account for one-half of all world population growth through 2050…

By 2025, the population of Bangladesh could reach 206 million people, China 1.45 billion, India 1.37 billion, Indonesia 272 million, Nigeria 202 million, and Pakistan 250 million…

By 2015, 21 cities will have populations above ten million. The top three are Tokyo (27.2 million), Dhaka (22.8 million), and Mumbai (22.6 million)...
