Seven billion

NPR reports on global population trends, which will bring us to seven billion strong in October or November. Several nice quotes by the eminently quotable David Bloom of Harvard are included.

I'm refereeing a paper on population momentum right now, which is responsible for a large part of the continuing increases in population levels. Even though fertility rates have fallen in many parts of the globe, age structures favoring the young mean that crude birth rates remain quite high and will continue for some time.
