The current (estimated) average birth-rate in the world is 20.3 births per 1,000 people per year. Going by estimates of a current world population of 6.5 billion people, that's about 132 million people being born each year, or 11 million each month.
Meanwhile the mortality rate is about 8.3 deaths per 1,000 people per year. Which means about 54 million dying each year, or 4.5 million a month.
The difference = (about) 78 million people being added to the population each year. Or around 6.5 million people a month.
The point? Nothing really. Just doomsday-mongering. And how's your day been?
