World Population to Reach 11 Billion by 2100: Study

Researchers at the University of Washington and the United Nations used modern statistical tools to estimate the number of people inhabiting the world by the end of the 21st century. According to their calculations, population growth will continue throughout this century and will reach a whopping 11 billion by 2100.
Previous estimates had suggested that population growth will slow down in the next few decades and reach around 9 billion people by the start of the next century.
"The consensus over the past 20 years or so was that world population, which is currently around 7 billion, would go up to 9 billion and level off or probably decline," said corresponding author Adrian Raftery, a UW professor of statistics and of sociology. "We found there's a 70 percent probability the world population will not stabilize this century. Population, which had sort of fallen off the world's agenda, remains a very important issue."
An expanding population is expected to put enormous pressure on the already limited food sources and healthcare.
