The Challenging Billions
While the human race took perhaps one million years to reach one billion people (around the year 1800), we have been adding successive billions every 10-20 years since 1960. Will we be able to meet the population challenge, just as we have met previous challenges, through technological and institutional innovation?

CAMBRIDGE – The world is in the midst of the greatest demographic upheaval in human history. Although the human race took perhaps one million years to reach one billion people (around the year 1800), we have been adding successive billions every 10-20 years since 1960. The world’s population now stands at seven billion and is projected to reach 9.3 billion by 2050.
