How much sex are people having, and how often do they get pregnant? All sizes.
Hans Rosling of Gapminder tweeted this: “Yearly 100 billion intercourses yields 200 million pregnancies resulting in 135 million births of which 127 million kids survive to year 5!”. I found it interesting and made the infographic above.
Only additions are to divide everything by 365, giving a daily figure. I somehow find it impossible to comprehend 100 billion intercourses.
What’s striking is how rarely sex leads to pregnancy (1 out of 500 times) and how much child mortality has decreased. I tried to make the whole thing a birthday cake, with sex as the platter. As you can see, however, the cake (babies) is not even visible. Have to do a little highlight and enlarge. It’s microscopic. Unless you’re having a baby, then it’s like OH MY GOD.
There are some other stats Rosling tweeted that are relevant:
World has 1 abortion/2500 intercourses, = 40 million abortions/year. Drop more likely from condoms than from ultrasound http://is.gd/sXH8R9
Births in the world now peaks at 135 million/year & life span is 70 years, hence by 2080 we will be 135×70=9.5 billions, so turn green fast!
Basically, people are still having enough sex to procreate plenty. At 100 billion hook-ups per year, that’s still around 17 intercourses for every man woman and child on earth (6 billion). While birth rates are slowing, they should (and probably will) slow more.
