World Population Will Hit 7 Billion In 2011 Putting Pressure On Developing Nations

The world population will reach 7 billion by the end of 2011, according to a new study released by the Harvard School of Public Health. Accompanying the population growth is a shift in the “demographic center of gravity” toward poor nations. Wealthier countries will see their populations age, but their numbers will remain relatively stable. The less-developed world, however, will cope with 97 percent of population growth over the next 40 years — almost half of which will fall to Africa. — Sarah Bufkin
